Embodiment Construction

[0015] The embodiment provided by the present invention is described in further detail:

[0016] A kind of argon arc welding process of iron plate, comprises the following steps:

[0017] (1) Processing of weldments and selection of welding materials

[0018] First, remove the dirt on the surface of the parts to be welded to ensure the dryness of the welded parts;

[0019] Second, the selection of welding materials, the selection of welding wire;

[0020] (2) Temporary spot welding

[0021] First, argon arc welding is used for temporary spot welding, the welding current is 160-200A, the welding voltage is 20-24V, and the length of spot welding is 10-80mm;

[0022] Second, pay attention to temporary spot welding. The height and width of temporary spot welding must not exceed the size of the future weld. It should be a part of the future weld. The arc crater should be filled. Spot welding on the back side. After the front side is welded, the spot welding on the back side sho...

Abstract

The invention discloses an argon arc welding process for an iron plate. The argon arc welding process for the iron plate comprises the first step of processing of a welding part and selection of welding materials, the second step of temporary spot welding, the third step of welding, and the fourth step of postweld treatment. By means of the argon arc welding process for the iron plate, the welding steps are simplified, the welding mode is simple, material selection is accurate and standard, the welding quality of the iron plate can be guaranteed, the standard welding mode is provided for the iron plate, and rapid and safe welding of the iron plate is facilitated.

Description

technical field [0001] The invention belongs to the field of welding, in particular to an argon arc welding process for iron plates. Background technique [0002] At present, 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, ...
