Principle of Laser Welding
Laser welding is the process of joining materials by laser lightwithout using additional materials.
The solid state laser delivers a controlled energy into the material within a short time resulting in a minimal heat input.

SEAM versus SPOT Welding
Ø Percent overlap determines strength of weld and seal quality
Ø Structural welds 50%-60% overlap
Ø Hermetic welds 85%-95% overlap
Ø Cross section at interfacedetermines strength of weld
Ø Multiple spot welds for higher strength
ØWelding depth determined by peak power of laser pulse
