Embodiment Construction

[0021] An aluminum plate welding process is characterized in that: comprising the following steps:

[0022] (1) Preparation before welding

[0023] First, check whether the surface of the workpiece is wet. If the surface of the workpiece is wet, wait for it to dry before welding;

[0024] Second, use acetone and a rotary file to remove oil stains, aluminum chips, and oxide films on the end face and edge of the aluminum alloy plate within 20mm of the welded part to reveal the metallic luster;

[0025] Third, the welding method and the selection of welding materials, Ar gas shielded welding is used for welding, and the welding wire of H08Mn2SiA steel grade; the purity of Ar is 99.999%;

[0026] Fourth, paste a protective film on the plate, there must be no air bubbles in the protective film, and no protective film is attached 80mm inward from the weld;

[0027] (2) Temporary spot welding

[0028] First, according to the size of the welded structural parts, the lengt...

Abstract

The invention discloses an aluminum plate welding process, and relates to the technical field of welding processes. The aluminum plate welding process mainly includes the four steps of pre-weld preparation, tack weld, welding and post-weld treatment. By the adoption of the aluminum plate welding process, welding steps are simplified, the welding mode is simple, materials are accurately and standardly selected and used, the welding quality of steel pipes can be guaranteed, the standard welding mode is provided for aluminum plates with the thickness being 4 mm, and quick and safe welding of the aluminum plates with the thickness being 4 mm is facilitated.

Description

technical field [0001] The invention relates to the technical field of welding technology, in particular to an aluminum plate welding technology. 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, voltage, type of welding power supply,...
