这台焊机可焊接直径在150～350毫米的各种弯曲半径的虾米腰接管,见图1。该机是用现有的半自动电焊机头加上管上转动装置组合而成。经实际操作测定,可提高工效13倍,且焊缝质量好,美观整齐,并改善了工人劳动条件。操作时先将切割好的虾米腰分段用手工焊点固定型(焊缝不需开坡口),再用夹紧装置将其固定、找正焊缝平面后卡紧。而后,通过平衡铁和升降手轮调整焊机头位置, This welder can weld shrimp lumbar tubes of various bending radii of 150-350 mm in diameter, see Figure 1. The machine is the use of existing semi-automatic welding head with tube rotating device combination. The actual measurement, can improve work efficiency 13 times, and the weld quality, beautiful and tidy, and improve the working conditions of workers. The first operation of the shrimp sliced ​​shredded waist with a manual welding fixed type (weld without beating), and then use the clamping device to be fixed, to find the welding plane after clamping. Then, by balancing iron and lifting hand wheel to adjust the welding head position,
