Which is better gas arc welding or austenitic welding?
The coefficient of thermal expansion is lower than the austenitic types and is about the same as mild steel. Welding processes that tend to increase carbon pickup are not recommended. This would include the oxy-fuel gas process, carbon arc process, and gas metal arc welding with CO 2 shielding gas.See all results for this questionWhat kind of tungsten is used in arc welding?The gas tungsten arc welding process is widely used for thinner sections of stainless steel. The 2% tungsten is recommended and the electrode should be ground to a taper. Argon is normally used for gas shielding; however, argon-helium mixtures are sometimes used for automatic applications.See all results for this questionWhat kind of gas is used in arc welding?For gas tungsten arc welding (a.k.a TIG, or Heliarc®) the torch shielding gas is argon with a 2.5% addition of nitrogen, the range is 1 to 3% N 2.
