Embodiment Construction

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

[0016] A kind of argon arc welding process of T-shaped steel, described T-shaped steel is 16Mn, 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 10-100mm;

[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...

Abstract

The invention discloses a T-type steel argon arc welding process, which comprises the steps: 1 treatment of welding parts and selection of welding materials; 2 temporary spot welding; 3 welding; and 4 post-weld treatments. The T-type steel argon arc welding process simplifies welding steps, simple in welding mode, accurate and regulate in material selection, can guarantee welding quality of T-type steels, supplies a regulated welding mode, and is beneficial for rapid and safe welding of the T-type steels.

Description

technical field [0001] The invention belongs to the field of welding, in particular to an argon arc welding process for T-shaped steel. 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 suppl...
