Resistance Welding Fundamentals - AMADA WELD TECH
power supply. The resistance of the workpieces (R) is a function of the weld force and the materials used. The thermal constant “K” can be affected by part geometry, fixturing and weld force. The bulk and contact resistance values of the workpieces, electrodes, and their interfaces both cause and affect the amount of heat generated.

Laser Welding Fundamentals - AMADA WELD TECH
amadaweldtech.com1.3.1 Nd:YAG laser The laser rod used in Nd:YAG laser welders is a synthetic crystal of yttrium aluminum garnet (YAG). The YAG material is the “host” material, containing a small fraction of neodymium, the active element. The YAG crystal is an ideal host for the lasing material Nd3+, because it is physically hard, stable, optically
