LASER WELDING


the worst of the smoke and splatter of welding. “Keeping things clean is vital,” he said.


Kugler makes the point that laser welding is best when the part is designed for it. The fit up and metallurgy of the weld joint is easier to specify correctly if the design engineer knows that lasers are going to make it. “We are also going to see more in the very small sizes in low-power lasers,” he said. “We have the beam quality now to make very fine welds” with beam spot sizes down in the 20–50-mm range. With such fine quality, there is more difficulty in designing the equipment to move and guide the laser beam than in the sources itself. This includes imaging and fixturing components, as well as robust welding heads.


One such head is the new Fiber-


Weld head from Laser Mechanisms. Designed for harsh welding environ- ments the FiberWeld couples to fiber lasers of up to 8 kW and boasts all in- ternal wiring and simplified plumbing of coolant. It can be configured a number of different ways, with straight or right- angle fiber input, camera viewing, wire
