Stainless steel tube combination welding technology

Combination welding methods include: argon arc welding and plasma welding, high frequency welding and plasma welding, high frequency preheating and three torch argon arc welding, high frequency preheating and plasma and argon arc welding. The combination welding increases the welding speed significantly.

 

The welding seam quality of the combined welded steel pipe with high frequency preheating is equivalent to that of conventional argon arc welding and plasma welding. The welding operation is simple and the entire welding system is easy to be automated. This combination is easy to connect with the existing high frequency welding equipment, and the investment cost is low and the benefit is good.

 

Each welding method of stainless steel welded pipe has its own advantages and disadvantages. How to develop strengths and avoid weaknesses and combine several welding methods to form a new welding process to meet people's requirements for the quality and production efficiency of stainless steel welded pipes is a new trend in the development of stainless steel welded pipe technology.
