The Quasi-continuous fiber laser welding machine developed by Friends ranges from 150W to 1500W, with higher electro-optical conversion efficiency, better optical quality and lower maintenance cost. This series product is a perfect alternative of existing light-pumped YAG laser and is an ideal choice for spot welding, seam welding, boring and other industrial applications，which requires wide pulse and high peak out power due to its diversified compatibility and the convenience for most YAG systems to use with simple transformation. Friends laser has a R&D teams with outstanding innovation ability and it can meet diversified demands of the customers. This series product, with rate output power of 10-100%，electro-optical conversion efficiency higher than 25% and modulation working frequency up to 5kHz，can meet the demands of most application scenarios.

The LWF series fiber laser welding machine is widely used in optical communication devices， IT device, Precision welding of aviation components, fuel injectors, Diesel supply system, solenoid valves, precision clock parts, automotive headlights, and other products.

The equipment can also meet the stringent welding requirements of medical devices, new energy battery components and micro-joints of 3C electronic products, and is especially suitable for high value-added products that require aseptic environments or vacuum sealing scenarios.
