Laser Welding Diagram

A laser welding device amplifies an input of light producing an extremely narrow and intensive beam on the weld surface with deep penetration. When two component plastic parts need to be joined laser welding employs four basic steps to accomplish the task. Laser beam welding lbw is a welding technique used to join pieces of metal or thermoplastics through the use of a laser the beam provides a concentrated heat source allowing for narrow deep welds and high welding rates.

Laser welding is a process developed and patented by branson.

Laser welding diagram. Laser stands for light amplification by stimulated emission of radiation. The temperature required for this phenomenon is around 300c above the surrounding temperature. In arc augmented laser welding the arc from a tig or mig torch is mounted close to the laser beam interaction point. Laser beam welding is a fusion welding process in which two metal pieces are joined together by the use of laser.

If the beam is focused on a metal surface it can raise the temperature to melting. 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 surfaces of the workpiece melt bonding the two parts together. Combining laser and gas tungsten arc gta welding can produce deeper weld penetration.

Results in a narrow weld zone and haz. The laser beams are focused to the cavity between the two metal pieces to be joined. Laser beam welding with diagram. 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.

The tig torch will automatically lock onto the laser generated hot spot. Heat is generated by a concentrated high energy laser beam directed at the joint to be welded. Arc augmented laser welding diagram. Waveguides direct and distribute laser energy simultaneously and homogeneously along the weld line.

On this channel you can get education and knowledge for general. In this video we will discuss about what is laser beam welding we will also discuss its principle of operation of this welding.
