本文从转轮设计、制造和使用的角度提出了不锈钢转轮焊接材料选择与焊接工艺确定的基本准则。文章指出,正确认识和掌握被焊母材的焊接特性,根据转轮焊缝位置的特殊性,从焊接冶金因素入手,从接头受力状况着眼,才是正确选择材料与工艺的有效途径。 This paper presents the basic criteria for the selection of welding materials and the welding process of stainless steel runner from the perspective of the design, manufacture and use of the runner. The article points out that correctly understanding and grasping the welding characteristics of the base metal to be welded depends on the particularity of the position of the weld of the rotor and starting from the welding and metallurgical factors. It is an effective way to choose the material and the process correctly from the stress situation of the joint.
