Mountain Welding is an established manufacturer of industrial production systems with more than three decades of experience in the design and production of resistance welding systems.
The company currently focuses on fully and semi-automatic shock absorber lines and rim wheel assembly lines, drawing on extensive experience serving customers across diverse industrial sectors.
In 1992, Mountain Welding started with one core fundamental technology: the welding machine.
Since then, Mountain Welding has expanded and manufactured more than 2,000 welders for the automobile, agriculture, household appliance, architecture, and railroad industries. This manufacturing depth reflects long-term capability in delivering production systems built for consistent quality, reliable operation, and strong production performance.
The company’s resistance welding systems are used in the production of shock absorbers, wheels, fuel tanks, ring gears, drive shafts, drive bearings, rear axles, and other critical components. With proven application across high-demand industrial environments, Mountain Welding has built its market presence through experience, equipment volume, and adoption in a wide range of end-use industries.
Resistance seam welding is a variation of resistance spot welding with the main difference being that the welding electrodes are motor driven wheels rather than stationary rods. Ideal for sheet metal fabrication, this welding method passes an electric current through the sheets of metals to be joined while they are held together by a mechanical force in a lap configuration between shaped copper electrodes. As with other types of resistance welding, fusion is produced where the sheet surfaces come into contact due to this being the point of highest electrical resistance and thereby the place where heat generation is at its greatest.
The heat from the disc-shaped electrode wheels creates a continuous weld as the work pieces are fed between them, resulting in a rolling resistance weld or a non-hermetic seam weld.
Resistance seam welding can either use an intermittent motion, where the speed of the roller is not predetermined, or continuous motion seam welding where the speed of the electrode roller is predetermined before the current is supplied.
Resistance seam welding has the advantage of creating clear welds with no gas formation or welding fume. There is also no need to use filler materials to make the join, which can be made to be both gas and liquid tight, offering a number of applications.
The process can be fully automated, making it a highly repeatable process. In addition, resistance seam welding can create both a single seam weld and a parallel seam weld at the same time.
Due to the ability to make gas or liquid-tight joins, this process is well suited for creating items such as steel fuel tanks for vehicles, as well as tin cans, radiators or steel drums. Resistance seam welds can also be found on many types of barrel and exhaust systems.
Widely used for joining aircraft tanks, refrigerators and oil transformers, this process can be used for welding stainless steel, nickel alloys, and magnesium alloys.
