Virtual Welding
Train - Simulate - Perfect
The welding education of the future has a name: Virtual Welding. Trainees
learn to weld under realistic conditions of torch, work-piece and welding Realistic 3D simulator
parameter combinations. The arc and weld seam are created based on the
technique of the student and allows progressive improvement.

Steelers fans may not appreciate our specialty capabilities for
heavy-duty fabrication, but steel fabricators and others pick
us for project work because we’re a valuable team player.
Whether we’re fabricating 38 specialized steel raker girders for the seating
