Laser Welding (LW) is a welding process, in which heat is generated by a high energy laser beam targeted on the work piece. The laser beam heats and melts the work pieces edges, forming a joint. Laser Welding is used in electronics, communication and aerospace industry, for manufacture of medical and scientific instruments, for joining miniature components.
Advantages
Dissimilar metals can be welded
Easily automated process
High weld quality can be achieved
Very small delicate work pieces may be welded
Disadvantages
Low welding speed
High cost equipment
