Problems solved by technology

[0002] During the construction of the maintenance project in the electrolysis workshop of the aluminum plant, it is often encountered that some steel components need to be welded without stopping production. Because there will be a large electromagnetic field in the electrolysis workshop during the production process, during the welding process Arc deflection will occur due to the action of the magnetic field, resulting in difficult welding, poor welding quality, and low construction efficiency

Abstract

The invention relates to a method of welding under electromagnetic action. The method includes the steps that firstly, a protective cover for welding is made, wherein the protective cover is characterized by being formed by processing 1 mm steel plates, two side vertical faces of the protective cover are in a right trapezoid shape, the upper flat face and the rear vertical face of the protective cover are in a rectangle shape, an inspection port is formed in the upper end of the front inclined face of the protective cover, electrowelding protective glass is installed on the inspection port, aU-shaped welding hole is formed in the lower end of the middle of the front inclined face of the protective cover, and a handle is installed on one side square face of the protective cover; then, theprotective cover is placed on a to-be-welded portion, and a welding gun stretches into the protective cover for welding. The method has the advantages that the structure is simple, operation is convenient, the phenomenon of arc bias caused by electromagnetic action in the welding process is effectively prevented, and the welding quality and the construction efficiency are improved.

Description

1. Technical field: [0001] The invention relates to a welding method under electromagnetic action, which belongs to the field of steel structure engineering construction. 2. Background technology [0002] During the construction of the maintenance project in the electrolysis workshop of the aluminum plant, it is often encountered that some steel components need to be welded without stopping production. Because there will be a large electromagnetic field in the electrolysis workshop during the production process, during the welding process Arc deflection will occur due to the action of the magnetic field, resulting in difficult welding, poor welding quality, and low construction efficiency. 3. Contents of the invention: [0003] Aiming at the deficiencies of the prior art, the present invention proposes a welding method under electromagnetic action which is simple to operate and convenient to use. [0004] The technical scheme adopted in the present invention: [0005] Th...
