The more repairs are made to the defects in the welds of 310 pipes, the more cracks appear

Defects in the welds of 310 pipes: re-welding leads to further cracking; cracking easily occurs at the start and end points of welding. How to deal with this?
Thermal stress in welds is inevitable. By using polymer materials for weld repair and protection, such situations can be avoided. Of course, the medium and operating conditions also play a role.
What welding material is being used? Cracks and defects must be completely removed. .
There’s no issue with the material when using 310 welding wire; let’s check if it’s a problem with the welding process
It’s TIG welding, right? Weld more slowly and give it a try; make sure to provide protection and cooling
Is rapid cooling or slow cooling required?
It should cool down slowly, but I haven’t tried it
Cool naturally at room temperature. How is the weld evaluation?
Is it a new pipe or an old one? Are the cracks caused by delay cracking or by stress cracking resulting from intergranular corrosion?
