A Guide To Welding Stainless Steel

Welding is a process where two pieces of metal are joined together by a heat and welds the two pieces together. Welding is typically done with metals such as stainless steel because it is strong, corrosion-resistant, and easy to work with. There are many welding processes available, but the most common is shielded gas tungsten arc welding (SGTW).

There are many factors to consider when welding duplex stainless steel, such as the type of weld, the quality of the Stainless Steel, and the welding equipment.

Here are some general welding guidelines for welding stainless steel:

  • Always use a shielded gas atmosphere when welding stainless steel. Argon or helium are two common gases used for shielding.
  • Use a filler metal that is compatible with stainless steel, such as MIG or TIG Welding. Avoid using aluminum or other metals with a high content of silicon because they will cause inconsistent welds.
  • Use a penetration depth greater than the thickness of the material being welded to avoid thermal distortion and create a strong joint.
  • Clean the work area and surrounding surfaces before beginning welding to avoid contamination and unexpected problems.
  • Weld slowly and carefully to prevent heat distortion and warping of the material.

Keep all your welding materials organized and always have a fully charged battery on hand. This will help you stay on schedule and avoid wasting time trying to find an elusive tool.
