旋搅摩擦焊新技术用熔焊法焊接铝及铝合金必须使用惰性气体保护熔池。由于热裂等原因，有些铝合金不能采用熔化焊。铝的固相焊接技术是克服熔化焊缺点的有效方法，它主要包括扩散焊、摩擦焊、磁控弧对焊、闪光焊等，但这些固相焊接都不太适用于铝合金板带的对接焊和搭接焊... Friction stir welding new technology Welding welding with aluminum and aluminum alloy must use inert gas to protect the weld pool. Due to hot cracking and other reasons, some aluminum alloys can not be welded by melting. Aluminum solid-state welding technology is an effective way to overcome the disadvantages of fusion welding, which mainly includes diffusion welding, friction welding, magnetron arc welding, flash welding, etc. However, these solid-state welding are not suitable for the butt joint of aluminum alloy strip Welding and lap welding ...
