Laser welding machines are growing in popularity because the laser welding process operates at very high speeds with low heat generation and little or no distortion. The process also requires no filler material and naturally lends itself to automation for a stable, repeatable weld process.
Laser Welding is perhaps the most modern technology available to be adopted by numerous industries for component fabrication. High intensity lasers can be tightly focused and produce controllable heat on the surfaces to be welded very quickly. If you have material that can be damaged by the heat or extreme heat, this is the best way. If you want small and accurate welds then you are going to want to use Laser welding as this is what its known for.
The opportunities can embrace a number of different aspects,such as very low weld ditorition; aesthetic appearance; simplified design and reduced component size; reduced material wastage; reduced post-weld machining; ease of automation; high production rates; and high production weld numbers in relation to time between equipment maintenance periods. It was applied in electronic, medical, domestic appliance, automotive,specialist tube, machine tool and control valve.However, because of the high capital cost involved in purchasing this equipment, the cost of welding is also high.
A laser welding machine system comprising a housing having an opening through which workpieces may be passed; means for generating and directing a laser beam into a welding station within said housing; light trap means for inhibiting light from passing from said welding station through said opening to the exterior of said housing andconveyor means for conveying workpieces with step by step intermittent motion between workpiece loading and unloading stations located externally of said housing and said welding station through said housing opening and said light trap means whereby workpieces may be loaded and unloaded from the conveyor means at the loading and unloading stations as another workpiece is simultaneously welded at the welding station while the conveyor means is momentarily stationary.
This system offers obvious welding methods, such as spot welding, overlap welding, seam welding, seal welding. Some of the most important parts are manufactured in UK and Germany to assure their quality. Moreover, the whole system is automatically controlled by PC which enables easy and high-speed operation.
