SAFETY TIPS FOR YOUR STEEL FABRICATION BUSINESS

For Stainless Steel Pipe Supplier In Mumbai Contact Maha Bhairav Stainless Steel

Someone who fabricates plate products in the world of structural steel has to have an open mind. Think about it. “Structural” applies to beam and columns for steel-framed buildings; framing accessories such as clip angles.

Whether a deformed bar or an angle bar, it is of utmost importance that safety always is the main priority. And whether you are an amateur or professional, there are a few basic rules that you need to be aware of and well-acquainted with when working with steel materials and steel pipes.

Base plates, and angle bracings; and ornamental fabrications are meant to accentuate a building design and support it. Basically, you need to know a little about everything.

Using steel material and fabrication tools is one of the most vital components for construction projects here in the Philippines.

Trade and welding schools give you the basics about structural steel fabricating, but you definitely learn more on the job. That is why most young men and women face problems when they hit the shop floor as they are not fully aware of the various structural steel lessons related to structural steel fabrication.

Whenever possible, use a well-mounted vice to grip your piece while you’re working on it. This may not always be practical, but consider it whenever you can. Use a rag or piece of scrap leather to cushion the metal and keep from marring it.

This is one of the most necessary steps before starting any project. Your tools and materials should be meticulously checked for malfunctioning in order to ensure that they are in good working condition. Steel and metal fabrication utilizes many hand-operated tools such as shears with sharp edges that could easily cut through skin and tissue.

One of the biggest dangers of working with sheet metal is the potential for cuts and lacerations. Finished pieces of sheet metal are typically smoothed out on the sides to reduce the chance of cuts.

When a piece of sheet metal is still being fabricated in the factory, however, the edges may be sharp. Running your bare hand or fingers across the edge of a piece of sheet metal can easily cut into your flesh, creating an open laceration.

Before welding solid, it’s time to put the quality hat back on. Always check holes and framing accessories after tack welding. That way you won’t have to spend all day removing solid welds if something is out of place. Just breaking three or four tack welds is a lot easier.

Attention is the most fundamental principle for a successful and accident-free steel construction project. Many large machines are used in steel and metal fabrication projects, sheet metal workers are required to push and pull metal sheets into a machine while executing complete caution in order to prevent clothes from getting sucked in.

That led to an important lesson. When picking up a plate, lay the plate down and use spreader chains with bent plates on the chains to grab all four edges. Do not use hooks on the ends of chains to move the plate, and do not use clamps on painted material to avoid paint buildup.

This is where it is important to first know the past experience of the vendor in sectors that are relevant to yours. This check will ensure that the projects are submitted on time and as per the standards.

This is necessary before starting the project. The tools should be checked for malfunctioning and inspected to ensure that they are in good working condition.

This is because sheet metal fabrication workers use various types of manual or hand-operated tools. For instance, if there is a pair of shears with blunt edges, your workers may have a hard time cutting with them.

The engineering services sector is extremely wide. You may find a number of vendors who deliver steel detailing services, and also are well-recognized in the industry. But choosing them without knowing their past experience can put you at risk again.

The vendors might be good at handling the steel detailing for a small structural project, but may fail to meet the deadlines, or understand the project entirely, if the requirement is of detailing a complex building structure, such as hotels, airports or even ports.

This is where it is important to first know the past experience of the vendor in sectors that are relevant to yours. This check will ensure that the projects are submitted on time and as per the standards.

How to Prevent Rust on Metal

For Carbon Steel Pipes Suppliers In Mumbai Contact Maha Bhairav Stainless Steel

Rust is a form of iron oxide. It occurs when iron combines with the oxygen in the air causing it to corrode. Rust is the orange-brown discoloration that builds upon metal.

For example, iron tools are prone to rust from long-term exposure to moisture, while a copper roof will tarnish under the effects of the weather. While some metals stand up to corrosion better than others (depending on the environment), none are free from every type of corrosion.

Rust can affect iron and its alloys, including steel. Whenever you have iron, water, and oxygen together, you get rust. The main catalyst for rust to occur is water.

Although iron and steel structures seem solid to the eye, water molecules are able to penetrate microscopic gaps in the metal. This starts the process of corrosion.

If salt is present, for example in seawater, the corrosion will be more rapid. Exposure to sulfur dioxide and carbon dioxide will also hasten the corrosive process.

Each type of metal has different electrochemical properties. These properties determine the types of corrosion the part is vulnerable to.

Rust is a form of iron oxide which forms when iron or iron alloys (such as steel) interact with oxygen in the air and cause corrosion.

The primary cause for rust is water, which can penetrate microscopic gaps in metals and begin slowly causing them to simultaneously expand and weaken. If salt is present, the process only accelerates. Several other factors can cause rust, however. Let’s take a look at a few.

There’s a reason people use the iron for tools, machines, and buildings — iron is abundant, strong, and an essential part of nurturing life on earth.

However, as powerful as this metal is, it can be destroyed by the simple combination of oxygen and moisture. Yep, rust. Read through our rust prevention guide to learn how to stop rust on metal surfaces.

So does this happen to every metal that gets exposed to the elements? Not exactly, because technically only iron rusts. We know, you may be thinking: 

But everybody’s seen rusty copper pennies, and silver jewelry definitely looks rusty when it’s left in the water.” That’s because of metals like copper, aluminum, silver, and even gold experience corrosion. Corrosion is the result of a chemical reaction to an oxidant, and rust is a specific type of corrosion caused by water and oxidation.

The best method will effectively remove surface rust, but minimize impact to the bulk stainless steel substrate. Abrasive techniques like sandblasting, abrasive pads, or abrasive rubbing compounds can damage the surface finish and embed particulates into the surface.

Coatings can provide a layer of protection against corrosion by acting as a physical barrier between the metal parts and oxidizing elements in the environment. One common method is galvanization, in which manufacturers coat the part with a thin layer of zinc.

So, what’s the biggest difference between a green patina on a penny and rust on creaky iron chains? The patina on a penny is tarnished, meaning it doesn’t penetrate the materials below the surface.

Tarnish only affects the top layers of metal, and actually works as a seal to protect the deeper layers from oxygen that leads to more damage.

Ferrous metals like iron and steel can oxidize to form rust. This weakens the metal and can cause the failure of the part. To avoid rust and corrosion, a variety of different coatings can be applied to the metal. Coatings are designed to prevent oxidation by keeping the part from exposure to oxygen and water.

Many environmental factors impact the likelihood of corrosion. It helps to keep metal parts in a clean, dry place when not in use. If you intend to store them for a long time, consider using methods to control the level of sulfur, chloride, or oxygen in the surrounding environment.

Putting iron through different processes is one of the major causes of corrosion. It could be the cleaning process, or it could be a fabrication process like cold working, heat treating, machining, or handling. Protecting iron in this stage is crucial — and many manufacturers consider rust prevention at this stage.

Red rust is caused by the combination of moisture and a contaminant like salt, which is why it so often occurs near faucets, docks, tractors, cars, and ships. When you experience red rust, you’ll also notice uniform corrosion.

Drier than red and yellow rust, brown rust is caused by high oxygen and low moisture in the atmosphere. It can also be caused by contamination during the manufacturing stage. Brown rust is usually non-uniform, appearing in just some areas of the surface.

Clean the metal part or surface. It is important to remove any dirt or corrosion before applying any rust-preventative coating. Make sure the part is clean and dry.

Additional preparation may be necessary depending on the coating you are applying. Follow the coating manufacturer’s directions for further preparation.

Your overlap joint certainly has two sides, and possibly four. The idea of a seal weld is to seal up the overlap area. This means putting a weld bead along the edge opposite the main weld and along any other open edges.

The thing to remember though is that these aren’t structural welds. Their purpose is to seal up the gap between the two plates.

Galvanic corrosion is what happens when two metals of different potential come into direct contact and exchange electrons like a battery, resulting in the weaker metal corroding.

Also known as dissimilar metal corrosion, the corrosion increases with the increased difference in metal materials. Simply put, the greater the difference in the potential of two metals, the greater the corrosion.

When a current flows through a path other than the one it is intended for, that’s when stray current corrosion occurs. With stray current corrosion.

The corrosion only occurs at the point of discharge — so there is no corrosion along with the system that carries the current, or at the point of entry. Because of this, many “cases” of stray current corrosion are misdiagnosed cases of another type of corrosion.

Important Metal Drilling Tips to Remember

For Stainless Steel Round Bar Contact Maha Bhairav Stainless Steel In Mumbai

Many applications, usually involving either mounting parts or routing wiring and other materials, require holes to be drilled or punched into sheet metal. As with any other typical fabrication task, there isn’t always a right or wrong way to do the job. But, sometimes there is a better way. 

If possible, use a vise to secure the metal you’re going to drill. If that’s not possible, you need to have some means of keeping the metal stable so that it won’t move, as you’ll need both hands to operate the drill properly.

Slowly pull the trigger until the bit gains rotational speed being careful to keep it on target. Ultimately, the drill bit will win the contest and you’ll have bored that hole.

Switch bits and begin again if needed to finish off the final hole.  Add more lubrication often.  Stainless does not conduct hear well so the tip of the “drill bit” will get very hot, very quickly.

When drilling metal, the surface is often slippery. There’s a good chance your drill bit might slip off on your first try, leaving a big scratch and making you angrily throw away your drilling machine. In order to prevent this, first use a sharp object to make a dimple.

When the heat stays in the drill, the tool itself will begin to break down. In high-speed steel (HSS) drills, this heat will cause the tool to lose its hardness. In solid-carbide drills, microcracks can form on the cutting edges, which will eventually cause the drill to fail.

Run out is when the drill bit does not spin perfectly on the axis. Usually its the result of the drill bit being slightly crooked relative to the spindle so the longer the drill bit or the farther out in the chuck it held, the worse the run out becomes. 

Every drill press has some degree of running out. High-quality drill presses generally have less run out on average than cheap drill presses. Excess runs out shortens the life of your drill bits and causes oversized or out of round holes.

You’ll achieve a much more accurate hole when metal drilling if you punch the hole first. This eliminates the possibility of the drill slipping on the metal, putting the hole in the wrong place.

The punched hole doesn’t need to be large. It just needs to be big enough for the tip of the drill. This will act as a guide and will help ensure that you have a square hole.

Once the hole centers are marked with ink or scribed crosshairs, use a center punch to strike each location. The dimples left by the center punch serve to guide drill bits and punch tips to prevent them from walking or wandering across the sheet metal surface.

Much of the time you need to drill slowly, as this gives more control and allows you to hold the drill more steadily. Because it’s easy for metal surfaces to buckle, the control is important.

As a general rule, you should never go faster than the middle speed when metal drilling. Going more slowly is also safer as the drill is less likely to slip and cause an injury.

Never ever hold a sheet-metal workpiece in your hands when drilling, and always clamp it down when you can. When setting up clamps or hold-downs, anticipate that a drill bit will catch and grab the workpiece.

And adjust your clamps to ensure that the metal cannot spin. What do you get when spinning sheet metal meets human flesh? A bad day if you’re lucky, a trip to the hospital if you’re not.

Knowing the correct bits to use when metal drilling will make the job a great deal easier. For soft metals, you should ideally use a step drill bit or a cone drill bit for the best results.

Both of these allow you to drill to different diameters; it all depends on how deep you drill. Where you’re not using one of these types of drill bits, start with a thin bit and work up to larger ones to increase the hole’s diameter.

Cooling is very important, especially when drilling hard metals like stainless steel since one property of stainless steel is that it gets harder when heated.

Drilling metal gets both the drill bit and the material extremely hot If you’re not cooling, the material will harden and drilling will get tougher and tougher. By using special cutting oil, you’ll be cooling both material and drill.

You should never drill metal without having proper safety equipment. Safety goggles, not glasses, are vital to stop small slivers of metal from entering your eyes; the glasses don’t offer adequate protection.

Not only is a backer board a good idea for reducing tear out, but it helps guide a hole saw’s pilot bit, keeping the tool aligned. When using larger saws on tougher material.

Cutting fluid can help make the job go easier and prolong the saw’s life. Manufacturers will usually provide a table of recommended RPMs according to hole size and the material being cut.

Gloves also help to protect your hands, although they’re not always compatible with the kind of fine control you need when metal drilling. Whenever possible, you should wear them.

To use a portable hand punch, first select and install a matching punch and die set. Align the point of the punch over a soon-to-be-hole’s center, and squeeze the tool’s handles together.

Once the punch clears through the sheet, a small slug will drop free and then the tool can be removed. Punched holes have relatively clean edges that require little to no finishing.

Rigidity in this application is the strength of the drill press to hold the drill bit and the shoe in the same position relative to each other. A good illustration of the lack of rigidity is when a drill bit “walks”. Poor rigidity makes run out worse, makes the setup prone to chatter, and makes it difficult to drill a hole where you want to drill a hole.
