Abstract

The invention belongs to a welding procedure and a device, particularly to a steel grid plate edge welding procedure and a device, and solves the problems with prior art including low working efficiency and insufficient strength of the steel grid plate end head. The technical proposal adopted is as follows: placing bound flat steel on the end heads of flat steel which is formed on the two ends of the steel grid plate and arranged longitudinally using a steel grid plate welder; pressing the intermediate electrode of the steel grid plate welder on the steel grid plate; and pressing a side electrode on the edge flat steel to conduct welding. A rectifier is connected with the side electrode linked with a lifting device, and a hold-down device is arranged on the outer side of the side electrode. The procedure and the device can be used for welding the steel grid plate edge, obviously improve production efficiency, reduce labor intensity and improve the strength of the steel grid plate end head.

Description

Technical field: [0001] The invention belongs to a welding process and equipment, in particular to a welding process and equipment for edge wrapping of steel gratings. Background technique: [0002] The steel grating is made of a number of flat steel bars arranged vertically, and several rows of cross bars are vertically welded on the side of the flat steel bars. Therefore, the two ends of the steel grating form the ends of the flat steel longitudinally arranged, and the flat steel needs to be welded to make it neat and beautiful and convenient to use. In the prior art, a portable welding machine is usually used to weld a welding spot every 3 to 4 longitudinal flat steels. Obviously, this method has low work efficiency, and the strength of the end part of the steel grating is not ideal. Invention content: [0003] The purpose of the present invention is to propose a steel grating edge wrapping welding process and equipment technical solution to solve the problems in the ...
