Energy beam welding
As the name suggests, the welding is done with the help of an energy beam. The beam of energy can be laser or an electron beam. This is a relatively new process that has gained a lot of popularity because of the high efficiency and the less amount of time that is consumed in the welding process. When talking about a laser beam, a highly focused beam of light is used for welding. In an electron welding setup, the metals to be joined is placed in a vacuum and a focused electron beam is used for welding the two pieces together. Both the laser and the electron beam have high density and this makes a deeper penetration possible. The processes are extremely fast and also can be automated easily. This makes the processes good for increasing the production rate. The initial costs and the cost of such equipment however are some drawbacks which has hampered its entry for regular use in the market.
