Laser Seam Steppers (LSS-5M) have been optimized for overlap welding of different materials such as aluminum, stainless steel, coated or hot formed steel as well as mixed joints. For more than 10 years Laser Seam Steppers have been established as an alternative for resistance spot welding. One area of application is automotive manufacturing, where millions of cars have already been welded with IPG Laser Seam Steppers. Laser Seam Stepper 特點：
Consistent higher-strength welds provide high quality joints and potential for lightweighting
Less heat-induced distortion for superior product finish
Compared to RSW, no electrodes to replace and no tool downtime
Integrated clamping technology for simplified production line integration
Shorter cycle time reduces number of systems required and takes less production floor space
