How to relieve stress in weldingThe FabricatorMetal
The welding gun deposits filler metal that becomes molten and expands from its previously cool state as wire or rod. Immediately after being deposited and subsequent fusion between the base and weld metal the metal cools quickly. The high-yield-strength weld filler metal contracts or shrinks pulling the lower-yield base metal with it.

Continuous castingWikipedia
Continuous casting also called strand casting is the process whereby molten metal is solidified into a "semifinished" billet bloom or slab for subsequent rolling in the finishing mills. Prior to the introduction of continuous casting in the 1950s steel was poured into stationary molds to form ingots.Since then "continuous casting" has evolved to achieve improved yield quality

How the fiber laser changed the rules of metal fabrication
Molten metal needs to be evacuated. A short focal length of the focusing optic means that the power density drops dramatically as you move away from the focus point position. This narrows the kerf and it also means the focus spot has to be in just the right place especially as the metal gets thicker.
