Description
Technical field
The present invention relates to welding field, the method for specifically a kind of multi-layer sintering net Gas Tungsten Arc Welding.
Background technique
Multi-layer sintering net is formed by composite steel silk screen sintering, main filtration, for the filter screen of filter, due to
Phenomena such as filter has shape need to sintered meshwork, and while being sintered net forming is easy to happen fracture of wire, delamination, limits sintered meshwork
Shape needs to realize the molding of sintered meshwork by welding.
Since sintered meshwork is layer structure, every layer of steel wire diameter is also different, is easy to burn when directly being welded, make
Fracture of wire into the net, and welding process is high to the skill requirement of welder, welding efficiency is low, and qualification rate is low, weldquality stability
Difference needs to improve welding technique.
Summary of the invention
The present invention aiming at the above shortcomings existing in the prior art, provides a kind of multi-layer sintering net Gas Tungsten Arc Welding
Method carries out tape edge to sintered meshwork welding edge by the method for preset welding rod in advance.
The present invention is achieved by the following technical solutions, a kind of method of multi-layer sintering net Gas Tungsten Arc Welding, including
Following steps:
The first step processes the preset welding rod as packing material；
Second step assembles welding rod in sintered meshwork edge fit to be welded；
Third step carries out positioning welding using tungsten argon arc soldering method；
4th step carries out tape edge to sintered meshwork welding edge using Tig Welding welding rod and the sintered meshwork of not filling silk；
5th step will be assembled into docking form by the sintered meshwork of tape edge, and use argon tungsten-arc welding positioning welding；
6th step, Tig Welding pass through the sintered meshwork of tape edge processing, sintered meshwork are welded into certain shape.
Further, preset welding rod of the processing as packing material in the first step, it is desirable that material and sintering net materials one
It causes, for welding rod with a thickness of 1.5mm, welding rod length is consistent with sintered meshwork welding edge lengths, and welding rod width is 3mm；
Further, welding rod is compressed using tooling in the second step, welding rod end face need to be aligned with sintered meshwork welding edge, weldering
Item need to expose 1.5~2mm；
The method of multi-layer sintering net Gas Tungsten Arc Welding of the invention, compared with prior art, the advantage is that:
One, sintered meshwork welding edge is carried out by tape edge by using preset welding wire, then realizes the welding of sintered meshwork, it can be effective
Solder yield is improved, sintered meshwork is improved and directly welds the problem of burning.
Two, the method for multi-layer sintering net Gas Tungsten Arc Welding proposed by the present invention, it is easy to operate, it is adaptable, it is high-efficient.
