Tool for semi-automatic welding of arc-shaped welding seam

A limiting device and an adjusting device are arranged on a semi-automatic submerged arc welding machine body, the tool is suitable for welding of H-shaped steel wing plates and webs of different models, the problem that arc-shaped H-shaped steel is difficult to weld is mainly solved, but the tool can also be suitable for H-shaped steel of other shapes, and the welding efficiency is improved. The application range is wide and the practicability is high. The device adopts a semi-automatic mode, so that the welding efficiency is improved, and the time cost and the material cost are also saved. Meanwhile, the device is convenient to disassemble and assemble, simple to operate and easy to learn. 本实用新型公开了一种弧形焊缝半自动化焊接用工装，在半自动埋弧焊机本体上设置限位装置和调节装置，适用于不同型号的H型钢翼板和腹板的焊接，主要解决了弧形的H型钢在焊接时候的困难，但该设置还能够适用其他形状的H型钢，适用范围广泛，实用性强。该装置使用半自动的方式，提高了焊接的效率，也节约时间成本和材料成本。同时该装置拆装方便，操作简单，容易学习。
