利用有限元法对激光焊接时保护气体在小孔内部和表面气流状况进行了数值模拟，通过对不同焊接条件下模拟形成的小孔气动扰流的气流场和压力分布云图的分析，解释了采用逆向侧吹保护气体吹除等离子体的方法，可以更有效地抑制等离子体云的产生，防止小孔塌陷，有利于维持小孔的稳定性。

At the age of 72 Weld passionately undertook to continue the tradition of his father Joseph, a founder member of the Royal Yacht Squadron and the owner of two former Lulworths.

维尔德的父亲是皇家游艇舰队的创设者之一，同时也是前两艘Lulworth的拥有者。虽年近72岁，他却充满热情地投入了父亲约瑟夫的事业。

The relationships between welding pool width, wire extension and welding parameters including welding current duty ratio, base current, peak current, welding speed and wire-feeding speed were studied. Through large numbers of welding experiments, aluminum alloy pulsed MIG welding dynamic process were identified by the curve fitting method, and the mathematical models between welding current duty ratio, base current, welding speed, wire-feeding speed and wire extension were obtained, succeeding the model between the above parameters and weld pool width.
