How to solve the problem of stainless steel pipe weld size?

Problems with stainless steel pipe weld seam in welding will lead to a reduction in the bearing capacity of stainless steel pipe, shorten the service life, and even cause brittle fracture.

Stainless steel pipe weld seam problem:

Weld seam size does not meet the requirements mainly refers to the weld residual height and residual height difference, weld width and width difference, the amount of misalignment, post-weld deformation, etc. does not meet the dimensions specified in the standard, the weld seam is uneven, the width is not uniform, the deformation is large, etc..

Weld width inconsistency, in addition to causing the weld formation is not beautiful, but also affects the weld and base material bonding strength.

The weld is too high, resulting in stress concentration, and the weld is lower than the base material, you can not get enough joint strength; wrong edge and deformation is too large, it will make the force transmission distortion and stress concentration, resulting in a decline in strength.

Causes: stainless steel welded pipe bevel angle is not appropriate or blunt edge and assembly gap is not uniform; welding process parameters are not reasonable; welder's operating skills level is low.

Preventive measures: select the appropriate bevel angle and assembly gap; improve the quality of assembly; select the appropriate welding process parameters; improve the welder's operating skill level.
