Welding treatment process for steel structure made of cold-rolled steel

Abstract

The invention relates to a welding treatment process for a steel structure made of cold-rolled steel and particularly relates to a welding clamp for the steel structure made of the cold-rolled steel.The clamp comprises a clamp table, an adjustable steel part supporting mechanism, an alignment clamping mechanism and a pressing mechanism, wherein the adjustable steel part supporting mechanism comprises two supporting tables capable of moving in the opposite directions or moving in the opposite directions, each supporting table is provided with two aligning and clamping mechanisms, and each aligning and clamping mechanism comprises a clamping sliding plate, a clamping air cylinder, an aligning air cylinder and an aligning plate. The clamp can automatically clamp and align channel steel and T-shaped steel to be spliced and welded, manual adjustment is not needed, the time and labor are saved, an operation risk of workers during operation is reduced, in addition, the T-shaped steel can beautomatically pressed after alignment, the tightness of the attaching position is guaranteed, manual additional pressing is not needed, and welding dislocation can be prevented.

Description

technical field [0001] The invention relates to the technical field of steel structure processing, and specifically proposes a welding process for manufacturing steel structures from cold-rolled steel. Background technique [0002] Cold rolling is made of hot-rolled coils as raw materials, which are rolled at room temperature below the recrystallization temperature. Cold-rolled steel plates are steel plates produced through cold-rolling processes, referred to as cold plates. The thickness of the cold-rolled plate is generally between 0.1-8.0mm. Cold-rolled is to further thin the steel plate to the target thickness at room temperature and below the recrystallization temperature. Compared with hot-rolled steel sheets, the thickness of cold-rolled steel sheets is more accurate, and the surface is smooth and beautiful. [0003] Sectional steel is a bar-shaped steel with a certain cross-sectional shape and size. It is one of the four major types of steel (plate, pipe, profile, a...

Problems solved by technology

[0003] Sectional steel is a bar-shaped steel with a certain cross-sectional shape and size. It is one of the four major types of steel (plate, pipe, profile, and wire). Common section steels include channel steel, T-shaped steel, I-shaped steel, and H-shaped steel. In the actual processing of steel structures, simple section steels are often used for assembly and welding to obtain steel structures that meet the needs of different occasions. For example, channel steel and T-section steel are assembled and welded to obtain new steel structures. In actual assembly In the welding production process, hoisting equipment is u
