SAW Welding Tractor is a self-propelled Tractor with Electric Flux Recovery System and Magnetic Device. The Tractor applies Submerged Arc Welding, more commonly abbreviated to SAW or Sub Arc Welding. SAW is mostly used on carbon steels, stainless steels and some nickel alloys; it improves productivity and consistently enables high-quality welds. SAW Welding Tractor, also known as Submerged Arc Welding Tractor, SAW Tractor, LT-7 Tractor, LT-7 Submerged Arc Welding Tractor and Lincoln LT-7 Tractor
Applications:
- Apply SAW Butt or Fillet welds on API Tank's Floors
- Apply SAW circumferential Fillet welds on Annular-Plate vs API Tank-Shell Bottom
- Apply circumferential SAW Butt weld on Tanks or Pressure Vessels while the tank rotates in the opposite direction then Tank Welding Rotators
