Lasers provide contact-free, high-speed metal welding solutions for advanced manufacturing. Laser welding operates in two fundamentally different modes: conduction limited welding and keyhole welding. The mode in which the laser beam will interact with the material it is welding will depend on the power density across the beam hitting the workpiece.
With GW fiber lasers, laser welding has become a highly reliable, easily automated process that provides the highest part quality, typically at the lowest processing costs, and virtually maintenance free.
Staying competitive today requires cost reductions, efficiency gains and repeatable part quality that cannot be met by traditional techniques that rely on increasingly scarce, highly-skilled craftsmen. Enabled by unprecedented no-maintenance, high-reliability and low-cost GW fiber lasers, laser welding systems have become the preferred welding solution for the manufacturing industry.
GMAW or MIG is a traditional technique using a consumable electrode that works well for larger, badly fitting parts.
Fiber laser welding does not use consumable electrodes, requires less edge preparation, is easily automated and is up to 5x faster. Fiber lasers also provide more precision, and lower heat input.
GTAW or TIG uses a non-consumable electrode and provides better process control than GMAW but any filler has to be added separately.
Fiber lasers are up to 10x faster with higher precision, lower heat input, and are more easily automated.
PAW is faster than GTAW, but much slower than laser welding. Having a large melt pool, PAW is good for badly aligned parts, but creates too much heat for many applications.
Fiber lasers offer higher precision, are faster, and have lower heat input in a non-contact process. Laser Wobble Welding is as effective on misaligned parts and does not require daily maintenance of the process head.
RSW is typically used for joining two pieces of material that are stacked on top of each other.
Fiber lasers only need single-side access, are much faster, and produce higher-strength welds. Fiber lasers do not require electrodes and eliminate the costs and time for electrode replacement.
EB welding provides excellent weld quality and a low heat affected zone. Because the process is in a vacuum chamber, contaminant levels are very low.
Fiber laser welding speed is similar to electron beam, but because lasers do not require part transfer through a vacuum chamber, laser cycle time is dramatically shorter.
