The main parts of the laser machine are described below. Equipment of Laser Beam Weldingįollowing are the main equipment of laser beam welding:Ī laser beam machine is a machine that is used to generate lasers for welding. This process continues and we get a focused laser beam that is used on the desired location for welding multiple pieces together. This light photon again stimulates the electrons of the atom and produces two photons. When they return to their low energy state or ground state they emit a photon of light.

The energy of light photons is absorbed by the atoms of ruby crystals and electrons are excited to their higher energy levels. It starts the machine’s flash lamp and it emits light photons. CAM is used to control the speed of the laser and workpiece table during the welding process. The lens is used to focus the laser into the area where welding is required. Later setup, a high voltage power supply is applied to the laser machine to perform an operation. Initially, the welding machine is setup (between the two metal pieces to join) at the desired location. Laser welding is used in the electronics, communications and aerospace industries, for the manufacture of medical and scientific equipment, joining small components.

In laser welding (LBM) the joint is made either as a sequence of overlapped spot welds or as a continuous weld. Laser Beam Machining (LBM) Working Principle.How Arc Welding is Done? Types of Arc Welding.Since the time the molten metal is in contact with the atmosphere is low, there is no contamination and therefore no gradient (neutral gas, flow) is required. The solidification of the weld pool surrounded by cold metal occurs as rapidly as the melt. The energy of a narrow laser beam is highly concentrated at 10 8-10 10 W/cm 2, so a weak weld pool is formed very rapidly (for about 10 -6 sec). The laser beam heats and melts the edges of the workpiece, forming a joint. Laser Beam Welding (LBW) is a welding process, in which heat is generated by a high energy laser beam targeted on the workpiece. Applications of Laser Beam Welding Process
