中文摘要: 现代焊接生产效率对焊接速度提出了越来越高的需求,但伴随而来的驼峰缺陷也成为限制焊速进一步提高的“瓶颈”。本文综述了高速焊接驼峰的形成机理,分析了其各自的特点,并明晰了高速焊接驼峰方面需要进一步研究的内容。
英文摘要:The welding speed has increasingly demands in production efficiency of modern welding, accompanied by humping defects which has become a "bottleneck"to further improve the welding speed. The formation mechanism of humping at high speed welding and its features were analyzed, and the develpment of further research in humping at high speed welding was investigated.
