Pipe Welding Techniques to Avoid 9 Common Issues

8 mins Cutting corners with cutting. When working with materials like stainless steel that are sensitive to Forgetting to grind the joint during weld prep. Operators may use plasma or oxy-fuel cutting to Improper tacking. Tacking is critical to pipe fit-up, and best practices recommend cutting out or Treating joint prep the same for MIG and stick. Training welders is a priority for many shops and Using the wrong shielding gas flow rate or mix. There is a misconception that more shielding gas is Misunderstanding porosity. Welding power sources typically dont cause porosity. To find the Using the wrong drive roll or nozzle. Its important to choose the proper type of drive roll for the Choosing the wrong MIG gun for the application. If pulsed MIG welding will be used, the MIG gun Buying a machine that cant handle the work. Pipe welding is its own animal.

Introduction to Welded Pipe Manufacturing - The Process

Electric Resistance Welding (ERW) ProcessSubmerged Arc Welding (Saw) ProcessElectric Flash Welding ProcessLap Welding ProcessIn Electric Resistance Welding (ERW) process, pipe is manufactured by cold-forming a flat sheet of steel into a cylindrical shape. Then current is passed between the two edges of the steel cylinder to heat the steel to a point at which the edges are forced together to form a bond without the use of welding filler material. Several Electric Resistance Welding (ERW) processes are available for pipe production. The two main types of ERW are 1.

The coatings and any metals containing these elements can give off toxic fumes if welded.
