Large Tonnage Press Brake Bending

The extreme tensile strengths of duplex stainless steels require extra large equipment for proper bending and forming. Northern's 24' press brake offers 660 tons of crushing force.

Hybrid Laser Welding

GMAW wire feed + Laser Welding

Hybrid laser welding is useful for very specific applications when filler metal is required. The laser beam is combined with the MIG welding weld puddle to push the molten filler metal deep into the weld joint. This process adds more heat and distortion than autogenous laser welding. It is generally used when the alloying filler metal is required for corrosion or strength, but can also be used to increase the weld speed or depth of penetration.
