What is the seam welder?
seam welder is a device that uses a variant of the welding technique of spot welding to weld continuous seams. The seam welders usually consist of two rotating wheels, each of which forms a separate electrode with a gap between them. The workpiece leaves are stretched by this gap, while the electric current is pulsated between the wheels. This electric pulse weld both leaves along with overlapping a series of "point" welds. The seam welders can melt both workpieces together or use another element of wire or metal foils to achieve various results. This causes the release of intense localized heat that melts both materials together in the "place". In conventional welding weld, where continuous welds are not required without gaps, these places are regularly distributed according to the specifications of the task. The seam router uses the same technique, but overlaps the places, and the gaping of the gap immediately, continuous welded seam.
The seam weld wheels used as electrodes are usually made of copper alloy and mounted on spindles that allow them to rotate freely. They remain stationary in relation to the workpieces that move between them. Between the wheels at the point where they meet, there is a pulse electrical discharge with a high voltage that connects two pieces. The intervals between the pulses are calculated according to the speed at which the workpieces progress, giving the overlapping range of point welds.
seam welding techniques differ according to welded materials, their thickness and possible use of the welded item. The steel coated with light used for fuel tanks and tin can cans is often welded by the seam using another element of copper wire powered between the two leaves at the weld point. Water radiators and tanks are usually welded without other materials used in the seam. The length of the copper wire can also be powered between the seams and the workpiece in the so -called welding of consumer DRag.
welding seams on Mash uses a technique where two leaves of steel with light are partially crushed during welding. The welding of the seams on the foil uses a strip of stainless steel foil located above and below the assing of the buttocks in the leaves. This foil strip maintains resistance to corrosion coated steel leaves. The seam welder holds several different advantages over other arc welding techniques. These include high welding speed and very small smoke formation.
