Weld thermal cycle simulation was used to reproduce the structure in the HAZ of single run and multi-layerwelding.
采用焊接热模拟再现了单道焊和多层焊haz的组织。
2
The properties of the welded joint may be effectively enhanced by adopting neat multi-layerwelding and technical welds.
多层焊和附加工艺焊缝是提高焊接接头性能的有效途径。
3
The temperature field and residual stress field of 3d single-layerwelding and multi-layerwelding were obtained, and the calculation results were discussed.
