Terminal (negative and positive) are the two parts connecting between connector and circuit. It can also be welded to make a module or pack in a certain design. These parts should also be well handled to have good current transmitting property. Therefore, fiber laser/hybrid wave welding is the best.
Laser heat treating is a surface modification process designed to change the microstructure of the metals through controlled heating and cooling. The advantage of utilizing a laser for this process is the ability to heat treat localized areas without affecting the entire workpiece. Due to minimal heat input, most processes are effectively used for self-quenching of products, saving time and money associated with quenchants.
