Laser Welding

Laser welding utilizes a beam of laser light to melt and fuse material across the weld joint.  The molten metal solidifies on cooling to form a weld.  Laser welding is a non-contact process and does not require any electrical connection to complete the circuit as with arc welding.  As with all other welding processes, laser welders come in all shapes and sizes; from the jewelry welder where the parts are presented manually to the laser light to high-power 6 kW machines that can weld thick sheets of steel.  Compared to other welding processes, laser welding is relatively new and continues to gain ground with new opportunities and applications.  When it comes to welding of small parts, lasers are utilized for applications where access is difficult and contamination is unacceptable.  For large scale applications, laser welding works really well where distortion and welding speed are an issue.  There are multiple issues related to laser welding and some of them are discussed below:
