The classifications of cage welding machine

According to the different joint methods, the welding can be divided into lap welding, flat welding, foil parts butt welding, copper electrode welding, auxiliary fixture welding, etc

1. Lap seam welding is the same as spot welding, the lap joint can be stopped by a pair of rollers or a roller and a mandrel electrode, and the minimum lap amount of the joint is the same as spot welding. In addition to double-sided seam welding usually used for lap seam welding, there are single-side single-seam seam welding, single-side double-seam seam welding and small-diameter circular seam welding, etc., when the plate is wide or other reasons limit the rolling disk from both sides to the workpiece, single-side seam welding can be used. When small parts such as device seats are welded on the surface of large parts and there is a certain air tightness request, the roller rim welding placed vertically with each other can be used.

2, the lap amount of flat roll welding is much smaller than that of ordinary roll welding, about 1 to 1.5 times the thickness of the plate, and the joint is flattened at the same time of welding, and the thickness of the welded joint is 1.2 to 1.5 times the thickness of the plate. Usually a cylindrical surface roller is used, and its width should fully cover the overlap part of the joint, and large welding pressure and continuous current should be used when welding.

3. In order to save metal, reduce weight, reduce deformation of welding structure, and improve fatigue strength, butt seam welding with foil gasket can be used. The foil strips used can be stainless steel or titanium alloy foil strips, and can also be similar metals.

4, copper wire electrode seam welding is an effective way to deal with coated steel plate when the coating is stuck to the roller. When welding, the round copper wire is sent between the roller and the plate from time to time, the copper wire is continuously transmitted in the original state, and it is continuously wound out after the roller and does not pollute the roller.

5. When welding bellows and diaphragm boxes, due to thin parts, small stiffness and narrow welding, auxiliary fixture welding is used. Under normal conditions, the fixture is made of copper alloy to ensure good electrical conductivity and heat dissipation.
