Problems solved by technology

[0006] In the existing technology, most of the spot welding used in the steel grating manufacturing process adopts traditional power frequency welding and intermediate frequency welding; the upper and lower poles of the electrode must bypass the product, and the greater the distance between the product, the greater the current loss; if In the automatic production line, the lower electrode will hinder the passage of the transmission line, so the method of using the upper and lower electrodes is inefficient and the current loss is large, especially when welding large products, the farther the electrodes are, the greater the current loss

Description

technical field [0001] The invention relates to the technical field of steel grating manufacturing, in particular to an intermediate frequency welding machine and a welding method for steel grating manufacturing. Background technique [0002] Steel grating, also known as grid plate, is a kind of steel product that is cross-arranged with flat steel according to a certain spacing and cross bars, and welded into a square grid in the middle. Steel grating is mainly used as a gutter cover, steel structure Platform boards, steel ladder pedal boards, etc. Steel gratings have ventilation, lighting, heat dissipation, anti-skid, explosion-proof and other properties. At present, the production of steel gratings is mainly produced by large-scale professional welding equipment. When welding, spot welding is a commonly used one. Welding method. [0003] When the workpiece and the electrode are fixed, the resistance of the workpiece depends on its resistivity. Therefore, resistivity is a...
