Problems solved by technology

[0003] When using alloy powder to improve spot welding quality, it is necessary to prepare the alloy powder into a high-viscosity mixture with a volatile solvent, and then coat it on the surface of the metal material. The existing technology is to use a brush to brush the alloy powder on the welded lap At the joint, this treatment method is inefficient, and the quality of manual brushing is difficult to guarantee, and it is easy to cause spot welding quality problems due to uneven thickness

Abstract

The invention discloses a point welding alloy powder roll coating device comprising a base. A lifting pressing seat is arranged above the base, a roll coating groove is formed in the lifting pressing seat, and a linear sliding piece in parallel with the roll coating groove is fixed to the lifting pressing seat. A coating roll is arranged on the linear sliding piece, extends into the roll coating groove and rolls along the roll coating groove. The point welding alloy powder roll coating device has the remarkable effects that the surface of a metal plate can be efficiently, stably and uniformly coated with alloy powder in a multi-point mode; and operation is easy and rapid, abrasion is small after long-time using, the coating quality of the alloy powder is high, long acting and stabilization are achieved, and the point welding quality of brittle metal is improved advantageously.

Description

technical field [0001] The invention relates to a spot welding auxiliary device, in particular to a spot welding alloy powder roller coater. Background technique [0002] When spot welding metals such as Mg and Al, due to their high brittleness, it is difficult to form a solid solution during spot welding, so the welding quality is not good. In an earlier study, the researchers found that for spot welding between homogeneous metal Mg, by using Cu-Al-Zn three metal powders, a microalloyed zone can be formed at the welded joint of metal Mg, thereby harvesting the nugget Regular symmetry, the excellent effect of increasing the size of the nugget; and in the follow-up research, it was found that for the spot welding between dissimilar metals, the use of appropriate alloy powder can also form a micro-alloyed area at the welded joint, improving the spot welding. welding quality. [0003] When using alloy powder to improve spot welding quality, it is necessary to prepare the allo...
