本文介绍了2103铝合金良好的焊接性能,接头机械性能及龙门号工作艇的建造工艺。着重阐述了控制焊接变形的工艺措施——采用半自动熔化极脉冲氩弧焊及带刚性夹紧装置的回转胎架。
This article describes the good weldability of 2103 aluminum alloy, the mechanical properties of the joint and the construction process of the Longmen working boat. Emphatically elaborated the technological measure that controls the welding deformation - uses the semiautomatic melting pole pulsed argon arc welding and the rotational carcass with the rigid clamping device.
