These cast tungsten carbides are added to the wire during the production process. Ideal for laser applications By using laser welding technology, the wire melts in the laser-formed weld pool without damaging the tungsten carbides. As this process has a low heat input and a fast cooling rate, the tungsten carbides are trapped during the solidification, ensuring an even distribution throughout the deposit. In contrast, using a different process with higher energy levels could damage the carbides or cause them to settle at the bottom of the weld pool.
