[0003] In steel plate wall welding construction, there is a very troublesome problem, the steel plate wall is super long and super wide, and the stability is very poor. Due to the asymmetric arrangement of weld, the local heating is uneven during welding, which causes unbalanced welding internal stress in the weldment.
