Ommeren Metaaltechniek has Cold Arc welding equipment available since February 2020.
This welding process is more efficient than other GMAW methods when the metal is thinner than 10 mm. The welding equipment detects a short circuit that sends a signal that causes the filler material to retract, cooling the seal time before each drop is placed. This leaves a smooth weld which is stronger than that of a hotter weld.
