It can be concluded that the local high temperature can be reduced effectively using the technique of discontinuouswelding and smaller residual stresses are obtained.
结果表明，采用间断焊可以有效降低焊接时的局部高温，而且其残余应力也略低于连续焊。
2
Welding process get worse with an increase in chromium content and smooth bead turn to be discontinuous.
随铬含量的增加焊道由光滑到不连续，焊接工艺性能变差。
3
The steel with discontinuous flowline microstructure has lower grooving corrosion susceptibility and only single corrosion groove exists along the welding line.
