Product Overview
Portable, handheld laser welding system designed for precise spot and seam welding across a range of metals. Compact unit providing low heat input and minimal distortion, suitable for micro components and assemblies with limited weldability.

Product Description
Laser welding uses a focused laser beam to generate heat at the weld zone. Due to its optical focusing properties, laser welding is ideal for small parts and materials with challenging weldability. The Senfeng portable handheld laser welding machine features low thermal input, reduced welding deformation and stable operation unaffected by electromagnetic fields.
