Abstract

Laser welding is one of the most important permanent welding operations that is widely used, especially in metal products. This type of welding provides some advantages and several technical properties such as minimum distortion around a welding link and minimum heat-affected zone. Therefore, the study aims to determine the technological requirements for the effective use of the operating laser beam welding in the production and assembly of metal products parts. It also aims to utilize and expand in the field of laser welding applications. One of the most important technological requirements that the study has achieved for using laser welding to connect product parts without affecting with welding heat used on the interface. Also, parts welding whether of similar or non-similar metals in terms of raw material. Also, it is not required in this welding use or non-use of intermediate material to connect product parts. And obtain connected required parts so that it does not require finishing after the completion of performing beam welding process. Also, joining thin and high-thickness parts of the product, high-precision welding, lower cost and speed. Using an automated way without human interference, get weld joints for product parts in large quantities in record time. However, the disadvantage of this technique is the high cost of equipment and machines it compared with the known conventional welding methods. The study made recommendations and results.
