Based on the self-developed "small core diameter" laser technology, the STR-HW series handheld laser welders adopt a new dual circuit refrigerant direct cooling system and integrated structural design. These welders can provide customers with such experiences as high effectiveness, large penetration, high energy-efficiency, and high convenience. Because these welders can weld various metal materials, they find broad applications including welding building materials; welding materials used to make home electrical appliances, kitchen hardware and bathroom hardware; sheet metal processing and pipeline processing.

The laser-plasma coaxial hybrid welding technology independently developed by STR eliminates the shortcomings of laser welding or plasma arc welding, and is widely used for precision welding of precision parts in aviation and space applications, of products in high-speed railway, subway and other rail transit applications, and of electronic products, etc. It has been certified that the welder adopting this technology can weld 6mm Series 7 aluminum plates and produce welded joints meeting Level I weld acceptance requirements.

Based on its independently developed passive components, STR Laser has achieved innovative breakthroughs in pumping technology. The 2kW narrow linewidth single mode fiber laser is its a mass-produced model utilizing the innovative 976nm pumping technology and adopting modular design. Featuring compact structure, good reliability and environmental adaptability, this model meets the requirements for ultra-high power beam combination and finds wide applications in industrial, medical, aerospace, and military fields.
