由于不同垮度和吨位的双梁吊的大梁上拱度和旁弯是不同的,同时上下盖板出来的檐也很窄,我们根据这一具体情况,改革了一台焊接大梁用的万向臂埋弧自动焊机。这种埋弧自动焊机,结构简单,操作方便,只要将嘴子固定在万向臂上利用嘴子卡在上下盖板和腹板之间的船形焊缝上就能进行自动焊,见图1。 Due to different degrees of collapse and tonnage double girder beam camber and side bends are different, while the eaves of the upper and lower cover is also very narrow, according to this specific situation, we have to reform a universal beam Arm submerged arc automatic welding machine. This submerged arc automatic welding machine, simple structure, easy to operate, as long as the mouth fixed to the universal arm on the use of the mouth card stuck in the boat between the upper and lower cover plate and the weld will be able to weld automatically, shown in Figure 1.
