To get the temperature field of discontinuouswelding exactly, thermocouple and IR-image equipment were used.
为了准确、全面地得到间断焊的温度场分布规律，采用了热电偶和红外热像仪两套数据采集系统。

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。

Welding process get worse with an increase in chromium content and smooth bead turn to be discontinuous.
