针对高强度结构钢母材,选用低匹配焊接材料,通过焊接工艺性试验,确定了最佳的工艺参数,焊接接头性能满足了设计要求,为今后焊接此类钢种,提供了有益的参考。
For the high strength structural steel base material, low matching welding material is selected, and the best technological parameters are determined through the welding process test. The performance of the welded joint meets the design requirements and provides a useful reference for the future welding of such steel.
