Problems solved by technology

[0006] The present invention can solve a: the existing sheet metal parts with a certain angle are easy to cause pressure on the opened sheet metal parts in the process of welding seam processing, so that the sheet metal parts are squeezed or stretched to cause cracks at the weld seam, or the sheet metal parts Deformation of metal parts, etc.; b: It is difficult to clean the weld seam of sheet metal parts with a certain angle, and the welding slag generated during the cleaning process is scattered around the weld seam, which increases the difficulty of weld seam cleaning and is easy to clean. Problems such as weld influence

Abstract

The invention provides an automobile sheet metal welding post-treatment process. The automobile sheet metal welding post-treatment process can solve the following problems that a, in the welding seamtreatment process of an existing sheet metal piece at a certain angle, pressure is prone to be caused on the sheet metal piece which is opened, then due to the fact that the sheet metal piece is extruded or stretched, the welding seam is cracked, or, the sheet metal piece is deformed and the like; and b, the welding seam of the sheet metal piece with the certain angle is difficult to clean, moreover, welding slag generated in the cleaning process is scattered around the welding seam, so that the welding seam cleaning difficulty is increased, and the cleaned welding seam is prone to be influenced and the like.

Description

technical field [0001] The invention relates to the technical field of sheet metal processing, in particular to a process for post-welding automobile sheet metal. Background technique [0002] The interior sheet metal parts of automobiles are mostly welded. According to the needs of the structure of automobile interior parts, multiple sheet metal parts are welded into a whole sheet metal part with a certain inclination angle; but when welding a sheet metal part with a certain inclination angle, the welding The weld seam is prone to bulge and there is welding slag around the weld seam, so it is necessary to perform subsequent grinding and other processing on the weld seam, but the following problems mainly exist in the existing processing: [0003] a: Existing sheet metal parts with a certain angle are easy to cause pressure on the opened sheet metal parts during welding seam processing, causing the sheet metal parts to be squeezed or stretched, resulting in cracking at the w...
