Embodiment Construction

[0022] A welding process for steel plates, characterized in that it comprises the following steps:

[0023] (1) Preparation before welding:

[0024] First, remove the dirt on the surface of the parts to be welded, such as iron filings, oil stains, etc.;

[0025] Second, choose the welding method and welding materials, use tungsten inert gas shielded welding, use H08Mn2SiA steel wire as the welding wire, and use an AC welding machine as the flux;

[0026] Third, clear the accumulated water and snow on the surface of the welded parts to ensure the dryness of the welded parts;

[0027] (2) Temporary spot welding:

[0028] First, the height and width of the temporary spot welding shall not exceed the size of the future weld, and shall be part of the future weld;

[0029] Second, according to the size of the welded structural parts, the length of spot welding can be selected as 50mm;

[0030] Third, fill the arc crater;

[0031] Fourth, the important welding structure should b...

Abstract

The invention discloses a welding technology for a steel plate and relates to the technical field of welding technologies. The welding technology includes four steps of preparing before welding, tack welding, welding and processing after welding. According to the welding technology for the steel plate, the welding steps are simplified, the welding mode is simple, material selection is accurate and standard, the welding quality of a steel pipe can be ensured, a standard welding mode is provided for the steel plate 1 millimeter in thickness, and the steel plate which is 1 mm in thickness can be easily, rapidly and safely welded.

Description

technical field [0001] The invention relates to the technical field of welding technology, in particular to a welding technology for 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 welding power supply...
