Their weldability is considered worse through study. The method of preheat and post heat treatment is neccessary to adopt for removing welding cold cracks and plug welding& welding stiffener for improving the jointing strength of welded joint. 研究认为它们的焊接性较差,需要采取预热和焊后热处理的方法来消除焊接冷裂纹,并采用塞焊和焊接加强筋来提高焊接接头的连接强度。
The main welding methods of stainless steel carbody contain spot welding, ring welding, plug welding, etc. Due to the structure features, large stress concentration at welding position can induce the fatigue failure. 不锈钢车体的主要焊接形式有点焊、环焊、塞焊等,焊接部位存在较大的应力集中,容易发生疲劳破坏。
