Stainless steel material welding polishing wiredrawing method and welding device used by stainless steel material welding polishing wiredrawing method

Abstract

The invention relates to a stainless steel material welding, grinding and wire drawing method and a welding device used. The steps include: 1) placing the thin stainless steel plate to be welded on a welding stand, and the surface of the welding position of the thin stainless steel plate is located on the left air guide Between the block and the right air guide block; 2), the external inert gas passes through the diverter valve along the pipeline, respectively passes through the left and right ventilation blocks, the left and right air guide blocks along the trachea, and finally reaches the surface of the thin plate stainless steel to be welded; during the welding process , the imported inert gas on the left and right sides forms two independent airflows on the welding surface, forming a pressure difference in the middle, so that the inert gas will completely discharge the air near the welding site, so that the welding pool is completely in the range of inert gas protection; 3) Use a polishing sheet to polish the welded part to remove fish scale spots; the present invention solves the situation that the surface of the product is oxidized due to the high temperature generated by the laser by using an external air blowing process.

Description

technical field [0001] The invention belongs to the technical field of stainless steel material welding, and in particular relates to a stainless steel material welding, grinding and drawing method and a welding device used therefor. Background technique [0002] Although the name is stainless steel, like many other metals, it will be oxidized and rusted when it is touched by hand or exposed to the air and affected by the environment. In addition, the surface of the stainless steel workpiece is processed by machining such as welding, stamping, crimping, heat treatment and other processes. A layer of black oxidized and degraded hardened layer is generally difficult to remove by mechanical means, which affects the performance of the material of the workpiece itself. [0003] In the prior art, laser welding and gas shielded welding are mainly used for welding thin-plate stainless steel. Laser welding has the advantages of high efficiency, non-contact, small thermal impact, lar...
