Problems encountered in welding thin wall stainless steel Problems encountered in welding thin wall stainless steel

Feb 19, 2018Problems encountered in welding thin wall stainless steel tubes. When welding thin wall stainless steel, the technical level requirements are very high, because in the welding of this kind of material, will face many problems, such as construction site problems, heat treatment problems, thermal expansion and cold contraction problems, the following to tell the solution to these problems. What causes discoloration on stainless steel welds?What causes discoloration on stainless steel welds?Figure 7A shows discoloration on a stainless steel weld caused by overheating, which not only affects a materials color but degrades its corrosion resistance and mechanical properties as well. Unfortunately, once this error is made, there is nothing that can be done to fix it except for scrapping the part and starting over.How to Solve 10 Common TIG Welding Problems [Guide]

What causes shrinkage in stainless steel butt welding?What causes shrinkage in stainless steel butt welding?Generally some shrinkage is typical of butt welding of pipes. Shrinkage due to butt welding could be more pronounced and significant in thin wall stainless steel pipes because the thermal expansion coefficient is roughly one and half times that of carbon steel.Simplified analysis of shrinkage in pipe to pipe butt welds What causes sugaring on a stainless steel weld?What causes sugaring on a stainless steel weld?Sugaring on stainless steel Figure 8 shows sugaring on the backside of a stainless steel weld. Sugaring (oxidation) occurs around the weld when it is exposed to oxygen in the air. The best way to prevent sugaring is to back purge the weld with argon shielding gas or reduce welding amperage. 9.

Assuming it welds just like carbon steel. Stainless steels have very different physical properties Using the same tools for both stainless steel and carbon steel. Stainless steel welding must be Not knowing the type/grade of stainless you are welding on. There are many grades of stainless, Using the shielding gas as used for carbon steel. Believe it or not this is extremely common. When Welding too hot. We see this specially with TIG welds. When you weld too hot you are essentially millerweldsImage millerweldsWhen welding thin wall stainless steel, the technical level requirements are very high, because in the welding of this kind of material, will face many problems, such asconstruction site problems, heat treatment problems, thermal expansion and cold contraction problems, the following to tell the solution to these problems.Problems encountered in welding thin wall stainless steel Problems encountered in welding thin wall stainless steel Was this helpful?People also askWhy does my stainless steel weld have too much amperage?Why does my stainless steel weld have too much amperage?Figure 8 shows sugaring on the backside of a stainless steel weld.
