Although welding temperature field and stress, strain field are bi-directional couple, because stress and strain field have little influence on temperature field, this paper only considers the single couple which temperature field effects on stress and strain field.
虽然焊接温度场与应力应变场是双向耦合的，由于应力应变场对温度场的影响非常小，加上计算条件的限制，所以本文只考虑温度场对应力应变场的影响这一单向耦合。
