Application - Laser Welding

Laser welding is the process of welding materials together, whether this is one piece or multiple pieces of similar or dissimilar materials. Renowned for the increased strengths of welds, laser welding is an application that businesses simply can’t afford to ignore for quality and cost reasons.

Industrial uses

The laser welding process is most frequently used in high volume industries, such as the automotive industry and in manufacturing. The process is extremely popular where the same welding operations are performed repetitively / continuously and can easily and seamlessly be integrated into other processes. This also makes laser welding extremely popular in other industries too, such as in electronics, engineering, medical, automotive, jewellery and manufacturing. Welding using lasers can also be used for other processes such as manufacturing fuel cells, batteries and fine wires for medical devices.

Benefits

There are many benefits associated with laser welding. Unlike with traditional welding, lasers guarantee the same accuracy consistently everytime, absolutely seamless and cosmetically attractive joints whilst also delivering the ability to weld even the most complicated of requirements. The process is also popular for the production of micro-precision parts, especially in the medical and electronics industries. The extremely low levels of thermal distortion can’t be emulated traditionally, which is another attraction of laser welding, as is the ability to weld in “difficult to reach” places. In general, there is no need to use flux or filler materials as welding joins can be programmed to work without the need for these.
