the weld defects of incomplete fusion and burn through always occur when the electro-slag welding is used between the outside thin metal plate and the inner clapboard in a box-section member.
箱形截面构件薄壁板与内隔板电渣焊接时,易产生壁板烧穿和焊缝未熔合现象。
according to it place position, incomplete fusion may divide into groove incomplete fusion, layer between the root department incomplete fusion of incomplete fusion 3 kinds.
按其所在部位,未熔合可分为坡口未熔合,层间未熔合根部未熔合三种。
c , . incomplete fusion prevent adopting greater welding current, use correctly to weld the cleaning of operating, notice groove position.
