Seam welding machine is a form of a permanent combination of metal welding. Welding, weldment pressed between two welding wheel, turn the welding wheel drive weldment and power, welding current through localized heating of the weldment has overlapping joints so as to constitute a continuous weld to achieve a permanent connection. Widely used in the cabinet, such as automotive, motorcycle fuel tank; barrel, such as oil drums and forming sheet metal workpiece, such as wheels, muffler, radiator seam welding.

Seam welding machine is usually from the rack, pressure welding wheel (electrode), trimmer, welding power, speed rotating mechanism and controller.

Pressurizing mechanism: transmit pressure evenly adjust the pressure and can compensate for electrode wear welding wheel.

Welding wheel and trimming knife: welding wheel inside and outside the water-cooled, conductive block with silver brush structure, electrical conductivity and automatically compensates for silver brush wear; the the trimmer butt round cylindrical molding cutting, to ensure that the work of the welding wheel the shape of the surface is good.

Welding power source: min exchange and secondary rectification DC two. The object of the workpiece, the welding process requirements selected.

Governor rotating mechanism and controller: frequency control, rotation of the gear reducer; controller is used as an important unit of the welding process. Seam welding machine, AC the secondary rectification DC seam welding two categories. The former applies to welding uncoated low carbon steel and alloy steel workpiece; latter is applicable for welding stainless steel, aluminum, aluminum alloys, titanium, titanium alloy, coated steel, and other materials of the workpiece. The basic types of the welder is divided into horizontal position (H) and vertical welding (Z).
