熔化极自动氩弧焊具有电流密度大、电弧穿透力强、焊接速度快、焊件变形量小、焊缝成形美观、接头质量高等优点。随着纯铝、紫铜及铜合金板材厚度的增大,焊接工作量显著增加,但采用自动操作,可在一定程度上改善焊工的劳动强度并降低了成本。纯铝的熔化极自动氩弧焊,在国内已有若干厂可进行正常生产,但厚度达30毫米的纯铝板的熔化极自动氩弧焊工艺则未见介绍。我厂为某项急需产品,进行了这方面的试验工作,并顺利地完成了三台87m~3 Melting automatic argon arc welding with current density, arc penetration, welding speed, weldment deformation is small, weld appearance, the advantages of high quality joints. With the increase of the thickness of pure aluminum, copper and copper alloy plates, the workload of welding has increased significantly. However, using automatic operation can improve the labor intensity and reduce the cost of welders to a certain extent. Pure aluminum melting electrode automatic welding, there are a number of factories in China can be normal production, but the thickness of 30 mm pure aluminum melting electrode automatic welding process is not introduced. I plant for a much-needed product, carried out in this area test work, and successfully completed the three 87m ~ 3
