Efficient full-automatic steel structure welding technology and method

Abstract

The invention relates to the technical field of steel structure welding, and discloses an efficient full-automatic steel structure welding method. The method comprises the following steps of selectinga welding mode, wherein the welding cost, the welding technology and modern mechanical and automatic production conditions are considered, and electric resistance welding can be selected as the welding mode. The efficient full-automatic steel structure welding technology and method have the advantages of achieving high efficiency, full automation and the like, and the problems that in the prior art, most of steel structures are welded in an electric resistance welding mode, although the characteristics of electric resistance welding in all aspects are suitable for large-batch large-scale production and automatic production, the defects that lack of fusion and incomplete fusion, shrinkage cavities, cracks, inward stretching of bonding wires, splashing and excessively deep indentation are generated in overlap joint welding, and butt joints are prone to dislocation, surface burn, incomplete penetration, gray spots, ferrite strips, lamellar tearing and brittle structures exist in the electric resistance welding process, and consequently automatic production is greatly hindered are solved.

Description

technical field [0001] The invention relates to the technical field of steel structure welding, in particular to an efficient and fully automatic steel structure welding technology and a method thereof. Background technique [0002] Steel structure welding manufacturing (that is, welding structure production) begins with the preparation of welding production, which includes structural review, process plan and process specification design, process evaluation, preparation of process documents (including quota preparation) and quality assurance documents , order raw materials and auxiliary materials, outsource and design and manufacture assembly-welding equipment and equipment, and then start the welding structure manufacturing process from material storage, including material re-inspection storage, material preparation and processing, assembly-welding, post-welding Heat treatment, quality inspection and finished product acceptance, which also interspersed with the whole proces...

Problems solved by technology

[0005] Aiming at the deficiencies of the existing technology, the present invention provides a high-efficiency fully automatic steel structure welding technology and its method, which has the advantages of realizing high-efficiency fully automatic, etc., and solves the problem that in the prior art, most of the steel structure welding adopts the resistance welding method, Although the characteristics of resistance welding are suitable for large-scale large-scale production and automatic production, in the process of resistance welding, lap joint welding is prone to incomplete fusion and incomplete fusion, shrinkage cavity, crack, joint line extension, spraying, etc. If the spatter and indentation are too deep, butt joints are prone to misalignment, surface burns, incomplete penetration, gray spots, ferrite bands, lamellar tearing and brittle structures, which pose a huge obstacle to automated production.
