Advantages of Laser Welding Process
1) Narrow deep penetration welds capable of being produced in atmosphere.
2) Low thermal distortion - due to less heat input and parallel sided fusion zone.
3) Narrow heat affected zone.
4) No contamination of filler or flames and hence environment friendly.
5) No filler metal required - it is possible to have filler materials, if necessary.
6) Welding can be done in inaccessible or hostile environments.
7) Multistation operation is possible using time sharing and beam splitting techniques.
