Material preparation is so critical that it is often documented to ensure consistency in the procedure, regardless of the material. Removing coatings such as paint, oils, greases, and rust (oxides) ensures that the area to be welded is in the best possible condition.

The classification of pipes is the schedule and nominal diameter. The pipe is typically ordered using the Nominal Pipe Size (NPS) standard and by specifying a nominal diameter (pipe size) and schedule number (wall thickness). The schedule number can be the same on different size pipe but the actual wall thickness will be different.

When working with carbon steels, it is critical to remove any rust and other impurities such as mill scale. Oil-based coatings and acidic pickling chemicals also must be removed before welding takes place. Removing chromium oxide to produce a decorative finish on stainless steel alloys often is achieved in a direct process.

Three important issues to consider when buying stainless steel are first and foremost a competitive price. When you buy a lot the mills and service centers give the best prices and that is a key concern for any buyer.

Operating speed is another critical component of proper weld preparation and cleaning. A good rule of thumb to remember when preparing a surface for welding is “slower is often faster.”

Using slow speeds to control friction helps to reduce surface and weld area contamination. High surface contact speeds can generate excess vibration, causing the abrasive material or brush tips to skip over surfaces, allowing impurities to remain. Fast operating speeds also can reduce your ability to control the tool.

Avoid removing too much of the parent material or creating deep scratches around the weld area. Removing too much material, also known as undercutting, may result in inclusions or poor arc control during the welding process. This is a serious concern if you are working with stock that has been reworked with plasma or torch cutting.

Typically, excess plasma dross or slag is removed with a chisel or ground off with a very coarse abrasive product. This can leave deep marks in the workpiece and drive surface impurities deep into the material to be welded, increasing the likelihood of weld porosity or poor coating adhesion at a later stage in the fabrication process. Any of these errors could result in costly rework.

In some instances the terms may be used interchangeably, however, there is one key difference between tube and pipe, particularly in how the material is ordered and toleranced. Tubing is used in structural applications so the outside diameter becomes the important dimension. Tubes are often put into applications such as medical devices that require precise outside diameters.
