Automatic Roll Welding Equipment

Automatic seam welding machines can be classified according to different specifications. Roll welding machine, also known as seam welding machine can be divided into lap roll welding, flattening roll welding, pad foil parts butt roll welding, copper electrode roll welding, auxiliary fixture roll welding, etc. Lap seam welding is the same as spot welding, depending on the joint method.
The weld of automatic seam welding machine consists of a weld joint, which is divided into roll spot welding or airtight seam welding according to the different condensation stack of the center. There are three stages of pressure, heating and solidification and cooling crystallization in the composition process of each solder joint, but it is quite different from spot welding. Due to the unavoidable shunt phenomenon, the current field and thermal field in the welding zone have their own characteristics. The pressure transmitting and electrified heating rollers rotate from time to time to change the welding position, so that the current field, the dispersion of the thermal field and the crystallization characteristics of the condensation zone are related to the speed of the changing position.
Lap joints can be roll welded with a pair of rollers or with a roller and a mandrel electrode, and the small overlap of the joint is the same as spot welding. Lap roll welding is usually used in double-sided roll welding, there are single-sided single-seam roll welding, single-sided double-seam roll welding and small-diameter circumferential roll welding, etc., when the plate is wide or other reasons limit the roller plate from both sides of the workpiece, roll welding machine is also known as seam welding machine can use single-sided roll welding. When welding small parts such as a device seat on the surface of a large part and there is a certain airtightness request, the butt welder can use a roller disk peripheral roll welding placed perpendicular to each other.
