Flexibility of the SISMA SWA Class 4 system! The "SWA" is designed for welding and repairing small and large pieces and molds. The laser transport in optical fiber provides great flexibility without significant power loss.

Designed and constructed for making modifications and repairs on molds damaged by wear or use. The SISMA SWA 150 and SWA 300 are lasers revolutionizing the conventional mold welding techniques. Material is added allowing repairs to be make without preheating the dies and with minimal heat transfer during the deposit process. Laser welding avoids classic damage caused by TIG welding such as: geometric distortions, burning of the edges and decarbonization. The properties of the laser beam make it possible to weld complex molds with deep and narrow grooves or inner and outer edges. All steels, bronze and copper alloys, aluminum and titanium can be welded. The hardness of the welding layers can reach very high values depending on the type of filler wire used.

Simple operating procedures and accurate visual control of the weld material using a stereomicroscope make this technology accessible to everyone, not just qualified engineers. The SWA 150 and SWA 300 units are powered by a flash lamp-pumped Nd:YAG laser generator with laser pulse transmission through optical fiber and is equipped with a system for movement along the motorized x, y, and z axes controlled by a joystick and button panel.

The laser source has been designed to guarantee high operating stability at both low and high power; fiber transport of the laser pulse provides a smaller beam diameter along with high stability of the laser spot, both in the initial transients and at various thermal loads of the laser source. The fully integrated cooling system is suitable for extended use. Motorized welding box for dies reparation complete with optic head with focal lens F120 and 10X stereomicroscope. Quick selection/setting of work by means of a color touch-screen display and with a memory up to 250 welding parameters. Axis X-Y Z motorized; Axis X stroke 300 mm; Axis Y stroke 150 mm and Axis Z stroke 500 mm. Axis Z is controlled by means of a joystick rotation. Made in Italy.
