Resistance Heating Machine utilizes electrical resistance to generate heat.
Resistance heating machines are used to soften metals by controlled heating and cooling, improving ductility and reducing hardness. Parmo's machines heat metals to high temperatures, followed by quenching, to increase strength and wear resistance. Resistance heating machines help in reducing internal stresses in metals after welding or mechanical work, enhancing their performance and longevity.
Resistance heating machines are an integral part of resistance welding techniques, including spot welding and seam welding, which rely on heat generated by electrical resistance to join metal parts. This involves joining two metal parts end-to-end by heating them with electrical resistance and applying pressure.
