A laser welding equipment that slows down the cooling rate of welding liquid

Abstract

The invention relates to the field of welding mechanical devices, in particular to a laser welding device for slowing down the welding fluid cooling rate. The laser welding device for slowing down thewelding fluid cooling rate includes a machine body, a laser head, a controller, a motor, tungsten plates, a first reflecting module, a second reflecting module, a first welding part, a second weldingpart, and a heat conducting block, wherein the laser head is connected to the side wall of the machine body through a fixing block; the controller is fixedly connected to the side wall of the machinebody and is located below the laser head; and the motor is fixedly connected to the left side of the machine body top. According to the laser welding device for slowing down the welding fluid coolingrate, a set of tungsten plates is arranged and light holes are formed in the tungsten plates to transfer heat generated by laser penetrating through the light holes to the first welding part and thesecond welding part to insulate an insulation zone and effectively slow down the cooling rate of welding fluids, bubbles in the welding fluids are fully discharged through air holes to the outside ofthe machine body, welding lines after welding are firm, and thus the laser welding quality is improved; and the laser welding device for slowing down the welding fluid cooling rate is simple in structure, convenient to operate, and good in welding quality.

Description

technical field [0001] The invention relates to the field of welding machinery and equipment, in particular to a laser welding equipment for slowing down the cooling rate of welding liquid. Background technique [0002] Laser welding is one of the important aspects of the application of laser processing material processing technology. In the 1970s, it was mainly used for welding thin-walled materials and low-speed welding. The welding process belongs to the heat conduction type, that is, the laser radiation heats the surface of the workpiece, and the surface heat diffuses to the interior through heat conduction. By controlling the laser pulse width, energy, peak power and repetition frequency and other parameters, Melt the workpiece to form a specific molten pool. Since laser welding is a high-quality, high-precision, low-distortion, high-efficiency and high-speed welding method, with the improvement of high-power CO2 and high-power YAG lasers and optical fiber transmission...

Problems solved by technology

[0003] However, the cooling speed of the welding liquid in the weld seam is fast after traditional laser welding equipment is welded, and the residual bubbles in the welding liquid cannot overflow in time, so that there are bubbles inside the welding liquid after cooling, the weld seam is not stable, and the welding quality is poor
