Laser Welding And The Equipment Used
Laser Welding is a fairly new way of fusing two pieces of metal together by using a laser heat instead of heat from a flame. This is a concept that has been accepted and used by many different industries, but especially in the automotive industry. The following paragraphs will briefly touch on the different type of equipment used during this process.
There are two types of equipment when it comes to fusing metal together using lasers instead of flames. One type uses gases while the other type uses solid media. Both methods let off protons to form the beams that actually weld the metal together.
Gas lasers are known to use higher voltage and lower current sources of power in order to supply the necessary energy to make the gas mixture that is used in the medium. Using this method, the lasers are able to perform in both pulsed and continuous modes. Power outputs can far supersede those of solid state equipment.
Solid state lasers operate on much shorter wavelengths than the gas ones. Because of this, operators are often required to wear eye protective gear in order to protect the retinas of their eyes from damage. They operate in pulsed mode, each pulse lasting about two milliseconds.
The most common gases used with gas metal fusing equipment are helium, carbon dioxide, and nitrogen. The most common solids used in the other method are synthetic ruby, neodymium commonly found in glass, and aluminum oxide. Both methods are being widely used by many different industries with their popularity continuing to grow.
We have learned so much about Laser Welding over the last decade while it was just in its infancy. There is a vast amount of information available to anyone with access to the internet. By using any search engine available, you can find the answers to any questions you may have regarding this very subject.
