It is to weld two stainless steel plates into one tank.
For the two welding methods, there are different opinions. Some people think that the effect of single-sided welding is actually better than double-sided welding. Some equipment with double-sided welding is because the wall thickness is too large, and single-sided welding is not easy to use. Double-sided welding, some people think that double-sided welding is worse than single-sided welding, single-sided welding is not as strong as double-sided welding, beautiful
1. The deformation of single-sided welding is larger than that of double-sided welding.
2. Single-sided welding, the appearance of the backside weld cannot be effectively controlled, and the double-sided welding mostly has the backside clear root, which can better control the weld quality.
3. The center layer of the thick plate is coarser and the strength is slightly lower than that of the surface of the plate. When the back side of the double-sided welding is welded, the front side is a tempered weld bead, which can better refine the metal grain of the blunt edge. It also releases part of the weld stress of the weld
4. The use of double-sided bevels for slabs is first and more economical in terms of savings compared to single-sided bevels. Secondly, the appearance of the weld surface directly affects the stress distribution of the weld.
