Description

Technical Field

[0001] The invention relates to the field of pole and disc welding equipment, in particular to a device capable of welding discs required on discs and poles to steel pipes according to requirements. Background Art

[0002] There are two ways to weld poles in the market. The first is manual welding, which can weld 50-60 poles at most every day. The efficiency is low, and the welding quality varies with the manual welding level. There are great hidden dangers when using it. The second is mechanical welding with a pole welding machine. The welding efficiency is 8-10 times that of manual welding. Usually, six or eight electric welders are used to weld at the same time. Although the welding efficiency is improved, the safety hazards during welding are greatly increased. The thickness of steel pipes on the market is uneven, and the thickness of the wheel is different, which will affect the welding effect.
