Laser Beam Welding Process Pdf

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.

Laser beam welding process pdf.

Laser beam welding is a fusion welding process in which two metal pieces are joined together by the use of laser. Laser beam welding lbw is a fusion joining process that produces coalescence of materials with the heat obtained from a concentrated beam of coherent monochromatic light impinging on the joint to be welded. During this process the laser beam melts the material and also creates a deep. 116 00 this document presents recommended practices for laser beam welding cutting and allied processes.

A ruby laser rod is used for machining process. The process is frequently used in high volume applications using automation as in the automotive industry it is based on keyhole or penetration mode welding. Laser beam welding lbw is a welding process in which heat is generated by a high energy laser beam targeted on the workpiece. This process is characterized by high efficiency and high welding speeds thanks to which the heat affected zone is small and the deformation is slight.

Laser is an acronym for light amplification by stimulated emission of radiation. Electrochemical machining ecm the subsystems of electro chemical machining. The intensity of the laser radiation is around 1 mw per square centimeter. Introduction and submerged arc welding process.

Laser welding is a process used to join together metals or thermoplastics using a laser beam to form a weld. Here the lasing material is in the form of a solid ruby rod doped with chromium with the end faces made parallel to each other within 1 20 of the. Being such a concentrated heat source in thin materials laser welding can be carried out at high welding speeds of metres per minute and in thicker materials can produce narrow deep welds between square edged parts. It is intended to cover common applications of the process.

Please refer to the branson tooling brochure for more information. The laser beams have enough energy and when it strikes the metal pieces produce heat that melts the material from the two metal pieces and fills the cavity. The laser beams are focused to the cavity between the two metal pieces to be joined. The laser beam heats and melts the edges of the workpiece forming a joint.

Printed hard copy download pdf. Laser beam welding is a welding process that uses a laser beam to melt and vaporize material. Laser welding process radial weld absorptive part converts laser to heat heat conducts across interface to melt both parts. C7 2m 2010 recommended practices for laser beam welding cutting and allied processes formats.
