This paper combines within the characteristics and problems of welding of the high strength aluminum alloys,introduces several advanced thickness plate aluminum alloy welding techniques and methods:friction stir welding,tandem MIG welding,laser-arc hybrid welding.
结合高强铝合金焊接的特点、难点,介绍了几种目前国际上焊接高强厚板铝合金的新工艺,新方法——搅拌摩擦焊、双丝MIG焊、激光-电弧焊;与传统电弧焊相比,它们在厚板高强铝合金焊接方面更具优越性。
The high-speed camera system and data acquisition system of welding parameters were created for tandem MIG welding of high strength aluminum alloy.
建立了高强铝合金双丝MIG焊熔滴过渡高速摄像系统以及焊接参数采集系统,获取了不同工艺规范下的脉冲熔滴过渡形式。
Because the heat input quantity during double-wire MIG welding thick plates was great,the welded joint was in the high temperature state for a long period of time and the former solidified metal experienced an "involuntary" aging treatment,which mean that the weld metal had reached the "peak aging" or sub-"peak aging" already.
试验发现20 mm厚2519铝合金双丝MIG焊接接头存在时效弱化问题,这是由于厚板双丝MIG焊热输入量大,接头长时间处于高温状态,已凝固焊缝金属相当于已经接受了一次时效处理,接头在焊后已经达到“峰失效”或接近“峰失效”的欠时效状态。
