【摘要】 在船舶、核电、汽车制造、压力容器、重型机械等行业中,大型结构件由于变位困难、成本高,不可避免的要采用立焊技术。同时,由于较大的焊接工作量,传统手工焊接已经不能满足实际生产中对效率的要求,因而迫切需要能够满足质量需求同时达到效率要求的高效立焊技术。更多还原

【Abstract】 It is inevitable to use vertical-weld cause of difficult displacement of the work which have large structures,in industries such as shipbuilding,nuclear power,automobile manufacturing,pressure vessel,heavy machinery and so on.Meanwhile,traditional manual weld can not meet the efficiency needed in the actual production,since the heavy welding work.Therefore,the highly efficient vertical-weld has become an urgent need that can reach the requirements of quality and efficiency at the same time.更多还原
