Laser welding is a welding process that uses high powered concentrated laser light to melt the material being welded. During the welding process light is absorbed by the material heating it up to form a small welding puddle.
ADVANTAGES of Laser Welding
Range of Applications and Materials
Laser welding can be used for a large number of applications to achieve faster and better results. The high welding speed can provide savings, especially when processing thin sheet metal. The minimal distortion and the beautiful weld appearance ensure post-processing costs can be kept to a minimum.
Speed 4 to 6 times faster than TIG
The progress rate with laser welding is considerably higher than with TIG welding. With laser welding, a welding speed can be achieved that is at least four to six times faster than TIG welding.
Less welding skill required and easier to learn
The basic skills of laser welding can be learned within a few hours. The welder must develop a feeling for the high speed and properly position the laser spot in the right place. Welding I-seams is often easier when a stop is used. The welding gun can then easily be advanced in the correct line.
Less post processing, grinding and polishing
Due to the high speed and the small melt pool, the surface area affected by the heat is also small. In almost all cases the weld seam can be cleaned in one go with a non-woven abrasive.
Due to the very low heat input during laser welding, the deformation of material is often negligible. By applying manual laser welding, you can save the time required for clamping the product. Less time will also be required to align products after welding.
