Nd:YAG laser welding machine W150G

buttseamspot

Overview
W150G is a YAG laser spot welding system engineered for precision repair and micro-welding of jewelry and small components. The unit combines a user-friendly interface, co-axial microscope observation and adjustable illumination to ensure accurate positioning with minimal thermal impact. It supports spot, butt and overlap sealing welds and delivers fine, smooth results that typically require little post-weld finishing.

Key features

• High aspect ratio with narrow weld width and limited heat-affected zone to minimize deformation and speed up cycles
• Smooth, clean weld seams with minimal or no post-processing
• High weld strength with low porosity; metallurgical refinement can match or exceed base metal strength
• Very small laser spot for precise positioning and easy automation
• Capability to weld certain dissimilar metals
• Multiple welding modes: spot, butt and overlap sealing
• Compatible with gold, silver, platinum, stainless steel, titanium and their alloys
• Adjustable spot size and ergonomic work chamber with adjustable LED illumination; optional extendable worktable
• Integrated water-circulation heat exchange plus forced-air cooling for stable operation

Applications

• Repair and assembly of gold, silver and platinum jewelry
• Stainless steel and titanium small-part welding
• Repair of dentures and dental components
• Micro-welding of battery nickel tape, integrated circuit leads, clock springs, picture tube parts and similar small components
