SUPER ULTRASONIC WELDING MACHINE A welding machine is a device that joins metal or plastic parts by applying heat, pressure, or both, typically to create a strong, permanent bond. These machines generate the necessary heat, often through electric arcs or gas flames, to melt and fuse the materials. Welding machines come in various types, including arc welders (MIG, TIG, stick), laser welders, and resistance welders, each suited for specific applications and materials. Key aspects of welding machines: Heat Generation: Welding machines produce the heat needed to melt or soften materials for joining. This can be achieved through various methods, including electric arcs, gas flames, high-frequency electromagnetic waves, or ultrasonic vibrations.
