Abstract

The invention relates to the technical field of welding, in particular to a laser recognition device and method for welding. The laser recognition device comprises a welding device, a clamp, a sensor unit, a protective cover, a shielding part and a gas flow path, wherein the sensor unit is installed on the welding device through the clamp, a welding torch is arranged at the lower end of the welding device, a welding wire is arranged at the lower end of the welding torch, the welding torch is provided with an arc-shaped buffer plate, and a workpiece is arranged at the lower end of the welding wire.The sensor unit comprises a containing box, a gas supply port, a first connecting terminal, a second connecting terminal, a light transmitting plate, a light projection part, a detection part and a first gas flow path. By arranging a cooling gas chamber, pressures of gases entering the cooling gas chamber from two upper end runners are equalized, so that the speeds of gases exhausted from deflation holes of two shielding parts are basically the same, and therefore, the stability of the system is improved.

Description

technical field [0001] The invention relates to the field of welding, in particular to a laser recognition device and method for welding. Background technique [0002] Conventionally, when butt welding or the like is performed by arc welding or the like on workpieces such as a pair of iron plates having a groove shape, the welding torch is brought close to the workpiece (the butted groove-shaped portion). In this state, a voltage is applied between the tip of the welding wire supplied from the welding torch and the workpiece, and an arc is generated between them. In this way, the welding wire melts, the workpieces are heated and melted, and the workpieces can be welded together. [0003] When welding, the distance between the welding torch and the workpiece or the shape of the workpiece has an impact on the welding quality of the workpiece. Therefore, in the welding process of the prior art, a sensor needs to be used to measure the distance between the welding torch and the...
