Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to a welding tool for doors used in civil air defense projects. Background Art

[0002] Civil defense, also known as civil defense, is an activity that takes measures to prevent air raids, resist disasters and provide relief, implements rescue operations, and prevents and mitigates disaster hazards. Civil defense door frames belong to civil defense protection equipment. Civil defense door frames include civil defense door frame bodies and civil defense door frames. At present, civil defense door frames are mostly welded from angle steels. During welding, most of them are manually positioned, clamped, and welded. Due to the large volume and weight of the angle steels that make up the civil defense door frames, the workload of the entire positioning, clamping, and welding is huge. The proportion of manual operation is too large, which can easily cause fatigue to the operators, resulting in low production efficiency. In addition, the quality of the welds produced by manual welding is unstable, and it is not easy to control the welding deformation of the workpiece, which affects the product qualification rate and increases the difficulty of subsequent workpiece correction.
