This paper has simulated the driving force of solidification crack of stainless steels, namely the, stress strain field in the trail of molten weld pool.

对不锈钢凝固裂纹的驱动力即熔池尾部应变场进行了模拟。

Weld spatter consists of particles of metal unintentionally ejected from the molten pool during welding and deposited on the surface of base or weld metal.

焊接溅落包括无意地从熔融池中溅出的金属颗粒并落到了母体金属或焊缝金属的表面。

By increasing the weld heat input, the distribution of martensite becomes more dispersive and glomerate due to the molten pool stiring, the welding stress and the burning loss of alloy elements.

随着焊接热输入量的增加，由于熔池搅拌、焊接应力、合金元素烧损等原因，马氏体的分布更加散乱和密集；
