Fiber laser welding machine SF1500HWM

manualfor metalfor carbon steel

Product overview
Fiber laser welding uses a high-intensity focused fiber laser beam to form metallurgical joints with high penetration and welding speed. Senfeng handheld fiber laser welding machines are designed for welding metal plates and tubes in industrial production and maintenance contexts. They combine compact gun ergonomics with centralized power units suitable for workshop use.

Main features

• High efficiency: welding productivity typically increases 2–10× compared with conventional arc methods.
• High quality: narrow, smooth weld seams often requiring little or no post‑grinding.
• Lower operating cost: replaces multiple arc welders and can reduce power consumption by 80%–90%.
• Flexible operation: 360° maneuverability of the hand gun; operable after brief operator training.
• Multifunctional: multiple welding modes (with or without filler wire); optional thin‑steel cutting capability.
• Multilingual UI: supports many interface languages for global deployment.
