Embodiment Construction

[0020] A kind of tungsten inert gas shielded welding process of aluminum plate, the thickness of aluminum plate is 4mm, it is characterized in that: comprise the following steps:

[0021] (1) Preparation before welding

[0022] First, remove the dirt on the surface of the welded parts, such as iron filings, oil stains, etc. If there is water or ice and snow, remove the accumulated water, ice and snow to ensure that the welded parts are dry;

[0023] Second, when welding below zero temperature, it is necessary to ensure that the weld can shrink freely during the welding process, and it is not allowed to hit the welded structure with a heavy cone;

[0024] Third, the choice of welding materials, choose the welding wire of H0Cr21Ni10 steel grade, the diameter of the welding wire is 3mm, the diameter of the tungsten pole is 4mm, the diameter of the nozzle is 8-12mm, and the welding machine adopts the AC mode;

[0025] (2) Temporary spot welding

[0026] First, use an AC ...

Abstract

The invention discloses a tungsten electrode inert gas shielded welding process of an aluminum plate and relates to the welding process technical field. The tungsten electrode inert gas shielded welding process mainly comprises four steps of preparation before welding, temporary spot welding, welding and treatment after the welding. According to the tungsten electrode inert gas shielded welding process of the aluminum plate, the welding steps are simplified, the welding method is simple, the material selection is accurate and standard, the welding quality of the aluminum plate can be ensured, a standard welding way is provided for the aluminum plate, and the rapid and safe welding on the aluminum plate is facilitated.

Description

technical field [0001] The invention relates to the technical field of welding technology, in particular to a tungsten inert gas shielded welding welding technology for aluminum plates. Background technique [0002] Different welding methods have different welding processes. The welding process is mainly determined according to the material, grade, chemical composition of the workpiece to be welded, the structure type of the weldment, and the welding performance requirements. First of all, it is necessary to determine the welding method, such as manual arc welding, submerged arc welding, argon tungsten arc welding, gas metal arc welding, etc. There are many types of welding methods, which can only be selected according to specific conditions. After the welding method is determined, the welding process parameters are formulated. The types of welding process parameters are different. For example, manual arc welding mainly includes: electrode type (or grade), diameter, current...
