Laser Welding And Its Advantages

Laser Welding is made use of in joining multiple metal pieces using laser beams. The beam gives a concentrated source of heat that gives provision for deep welds and high rates of joining. The expertise is made use of in applications that require a lot of welding, notably the automobile industry. It is a very efficient way of welding.

The knowledge was discovered by an American scholar of physics, Theodore Maiman in 1960. He obtained the first emissions using ruby crystals. Industrial uses were first implemented in the 1980s in France. It was applied in machining and micro machining.

The beam is very dense in terms of power, giving rise to minute heat affected regions of the material being welded. This results in very high rates of cooling and heating. The depth to which the beam penetrates is in proportion to the supplied power and where the focal point is located. The versatility of the process enables the joining of aluminium, steel, carbon steels and titanium.

There are several advantages of lasers. Whereas other types of joining require transmission through vacuum, it can be transmitted through the air. Secondly, the technology can easily be automated with robots, further enhancing its efficiency. Unlike other methods, x rays are not generated in the use of the technology. It also results in high quality welds.

In its use, the gases utilized are carbon dioxide, nitrogen and helium that provide the requisite media for joining. Solid media in use are aluminium oxide, chromium and ruby. There are two types of equipment used; gas and solid state lasers.

The concentrated beam emitted may be visible or invisible; hence care should be taken in the course of its use. The beams should not be focused on the skin or eyes as this would lead to damages on the organs. Instructions of use should be carefully read during Laser Welding for the sake of safety.
