SYSTEM DESCRIPTION

STW-F series laser welding system uses Nd3 +: YAG solid-state laser. After beam expander and reflection (or optical fiber transmission), the pulsed laser focused on the object. Work pieces can be hand-held or fixed by fixture, then the laser is triggered and fall on the work piece. Also, we can connect it with an external control system for automatic welding. Frequency, pulse width, worktable speed and the moving direction of the welding would be controlled by computer. By adjusting the frequency and pulse width of laser power, we can control the laser pulse energy.

FEATURE

  • With a high ratio of welding depth and width, weld width is small, small heat-affected zone, small deformation, and high welding speed.
  • Smooth and beautiful, no need to process after the welding.
  • High welding qualities, no pores, and can reduce and optimize the original impurities; it can be refined after welding. Weld strength and toughness are at least equal to or even stronger than the original metal.
  • Precise controls, small focused spot, high-precision positioning, easy for automation.
  • Able to weld some dissimilar material.
  • Able to process spot welding, butt welding and seal welding.
  • Compact size with embedded water chiller.

APPLICATION AREA

STW-F series welding machines can weld the materials like titanium, nickel, tin, copper, aluminum, chromium, niobium, gold, silver, steel and their alloys. And it also can weld compound materials like copper-nickel, nickel-titanium, titanium-molybdenum, brass-copper and low carbon steel-copper.
It is widely applied in the industries of mobile phone batteries, sensors, clocks, watches, jewelry, electronic components, eyeglasses, crafts, precision instruments, medical apparatus, etc.
