Embodiment Construction

[0019] A kind of argon arc welding process of 16Mn steel plate, the thickness of 16Mn steel plate is 4mm, it is characterized in that: comprise the following steps:

[0020] (1) Processing of weldments and selection of welding materials

[0021] First, remove the dirt on the surface of the parts to be welded, such as lumps of rust oxides, oil stains, etc. If there is water or snow on the surface of the welded parts, remove the accumulated water and snow on the surface of the welded parts to ensure that the welded parts are dry;

[0022] Second, the selection of welding materials, choose the welding wire of H10MnSi steel grade;

[0023] (2) Temporary spot welding

[0024] 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;

[0025] Second, pay attention to temporary spot welding. The height and width of temporary spot welding must not exceed the size of ...

Abstract

The invention discloses a 16 Mn steel plate argon arc welding process, and relates to the technical field of welding processes. The 16 Mn steel plate argon arc welding process mainly includes the steps of preparation before welding, tack weld, welding and treatment after welding. By means of the 16 Mn steel plate argon arc welding process, the welding steps are simplified, a welding mode is simple, material selection is precise and standard, the welding quality of 16 Mn steel plates can be guaranteed, the standard welding mode is provided for the 16 Mn steel plates, and quick and safe welding of the 16 Mn steel plates is facilitated.

Description

technical field [0001] The invention relates to the technical field of welding technology, in particular to an argon arc welding technology for 16Mn steel 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, voltage, type of weld...
