Combination of a Nd:YAG laser and a liquid cooling device to (Zr53Cu30Ni9Al8)Si0.5 bulk metallic glass welding

▶ A liquid cooling device (LCD) helps to produce a lower initial welding temperature. ▶ A lower initial welding temperature leads to a faster welding thermal cycle (WTC). ▶ A faster WTC produces a crystallization free weld for a laser welded Zr-based BMG.
