Laser spot welding

Application

• Nd:YAG laser spot welding of platinum coated stainless steel blades to stainless steel sprung support bars
• requirements for very high reliability and production rates
• produce 117 000 spot welds per hour
• alternative processes include resistance welding (electrode sticking problems), adhesives (long curing times), and CO ₂ laser welding (beam delivery difficult)
• estimated manufacturing cost £0.00002 per twin blade cartridge

Benefits

• flexibility of using a robotically manipulated, fibre delivered laser beam
• precision welding of 13 spot welds per blade
• minimum distortion
• good cosmetic appearance
