Describe the use of the following processes: LBO LBW, and LBC.

To determine

The use of laser beam drilling, laser beam cutting and welding.

Answer

LBD, LBW and LBC are laser assisted processes to drill, weld and cut the materials with precision and speed.

Explanation

Laser beam drilling is used for very hard materials with high precision and speed. The process of drilling holes is by shooting short bursts of high energy lasers at the required spot of drilling.

Laser beam welding is used to weld thin materials by concentrating the laser on the region. The main advantages of LBW are; it does not result in a little or no heat affected zone; deep penetration and high speed.The material needs to be electrically conducive.

Laser beam cutting is like laser beam welding as far as localized heating is considered. In addition, a jet of assisted gas is applied at the spotto expel the molten metal out of the hole.

Conclusion:

Thus, LBD, LBW and LBC are high energy laser assisted processes to drill, weld and cut materials with high precision and speed.
