Welding Copper Radiator. Laser welding can be used to weld thin brass radiator tubes that are superior to the thinnest conventional lock-seam or high-frequency welded tubes. Applications include automotive radiator cores and tanks lamp fixtures locks plumbing fittings and pump cylinders.
During the last several years Modine Manufacturing Company has been developing a high reliability durable heavy-duty class 7 and 8 truck radiator. The air-side of the tube-to-header joints are soldered to provide a dual bond that reinforces and seals the weld joint. This development work has culminated in the Beta-Weld radiator which was commercially offered to the heavy duty truck markets beginning.
