It is no secret that aluminum, along with many other non-ferrous materials, has been welded successfully by the Thermatool High Frequency welding method for many years now. As material costs change and aluminum is substituted for copper in many heat exchange applications new process requirements emerge. While the basic HF welding process varies from the method used to weld carbon steel, attention to material characteristics is necessary to ensure that a high-quality weld is achieved.
Recently, Thermatool has perfected impederless welding of small diameter aluminum tubing with an enhanced ID, with very high statistical quality levels.
