Embodiment Construction

[0018] The embodiment provided by the present invention is described in further detail:

[0019] A plate welding process, the thickness of the plate is 5mm, comprising the following steps:

[0020] (1) Preparation before welding

[0021] 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;

[0022] Second, clean the oil stains, aluminum chips, and oxide films on the welding parts to reveal the metallic luster;

[0023] Third, the selection of welding methods and 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%;

[0024] Fourth, stick a protective film on the board, and there must be no air bubbles in the protective film;

[0025] (2) Temporary spot welding

[0026] First, according to the size of the welded structural parts, the length of spot welding is selected from 10 to 90mm;

[0027] Second, pay atte...

Abstract

The invention discloses a plate material welding process, wherein the thickness of a plate material is 5mm, and comprises the steps: 1 preparation before welding; 2 tack welding; 3 welding; and 4 postweld treatments. The plate material welding process has the beneficial effects that the plate material welding process simplifies welding steps, simple in welding mode and accurate and normative in material selection, can guarantee welding quality of plate materials, supplies a normative welding mode for plate materials which are 5mm in thickness, and is beneficial for rapid and safe welding of aluminum materials which are 5mm in thickness.

Description

technical field [0001] The invention relates to the technical field of welding technology, and more specifically relates to a 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 s...
