A kind of welding process and welding structure

Abstract

The invention relates to the technical field of welding processes, in particular to a welding process and a welding structure. The welding process is suitable for butting joint between a first welding piece and a second welding piece and comprises the following steps that a plurality of first notches are formed in the first welding piece; the second welding piece comprises a folding edge, and a plurality of second notches are formed in the folding edge or the area corresponding to the folding edge on the second welding piece; the first welding piece and the second welding piece are assembled, and a sawtooth-shaped structure formed by the first notches of the first welding piece and a sawtooth-shaped structure formed by the second notches of the second welding piece are engaged correspondingly; and the first welding piece and the second welding piece are welded along the engaged lines of the first welding piece and the second welding piece. Meanwhile, the invention further provides the welding structure adopting the welding process to conduct welding. The sawtooth-shaped structures of the two welding pieces are mutually engaged, thus the contact area between the two welding pieces can be increased, and the structure strength between the welding pieces is improved accordingly; and meanwhile, the folding edge or a body covers a weld seam, so that the process of removing a crater is omitted.

Description

technical field [0001] The invention relates to the technical field of welding technology, in particular to a welding technology and a welding structure. Background technique [0002] Sheet metal processing is a key technology that sheet metal technicians need to master, and it is also an important process for forming sheet metal products. Sheet metal processing includes traditional cutting and blanking, processing blanking, bending and forming and other methods and process parameters, as well as various cold stamping die structures and process parameters, various equipment working principles and operating methods, as well as new stamping technology. and new technology. Part metal sheet processing is called sheet metal processing. [0003] Specifically, for example, using plates to make chimneys, iron drums, oil tanks, ventilation pipes, elbows, round places, funnel shapes, etc. The main processes include cutting, bending buckle, bending, welding, riveting, etc. Some know...
