Currently, magnesium welding presents stringent requirements: conventional magnesium alloy welding wires must be identical to the base metal. The company’s newly developed universal magnesium welding wire boasts excellent weld performance and broad applicability, enabling compatible welding of different grades of magnesium alloys as well as cast and extruded profiles (including tubes). This technology sets a pioneering precedent both domestically and internationally; it not only delivers superior weld quality but also exhibits outstanding compatibility, a small heat-affected zone, and excellent fluidity, thereby providing a reliable guarantee for high-quality magnesium alloy welding.
