摘要
厚度为1mm的304奥氏体不锈钢回转钢带,其边缘在运行中开裂,不能使用,需要焊接修复。通过焊接工艺试验和理化试验,筛选出了较适宜的焊接工艺参数。按照筛选出的工艺参数施焊,焊后经锤击及抛光,获得了较满意的修复质量,也为此类回转钢带裂纹的焊接修复提供了成功的经验。
A welding repair is required for the crack on the edge of Austenitic stainless steel ro- tary belt during its operation and fail in service. Through weld process test and physical testing and chemical analysis,a suitable wilding process is chosen for repairing the crack of austenitic stainless steel rotary steel belt.The weld was performed according to the process parameters, and hammering and polishing the post weld is an important for improving the quality of crack re- pair,and a successful experience of ...
