SAW Welding Tractor is a self-propelled Tractor with an Electric Flux Recovery System and a Magnetic Device. The Tractor applies Submerged Arc Welding, more commonly abbreviated to SAW or Sub Arc Welding. SAW is primarily used on carbon steels, stainless steels, and certain nickel alloys. It enhances productivity and consistently produces 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 the API Tank's Floors.
- Apply SAW circumferential Fillet welds on Annular-Plate vs API Tank-Shell Bottom.
- Apply a circumferential SAW Butt weld to tanks or pressure vessels while the tank rotates in the opposite direction, then use the Tank Welding Rotators.

Notes:
Our company recommends consulting a Certified Welding Engineer (CWEng) to design the welding procedure in accordance with the relevant national and provincial codes and standards. In Canada, CWEngs are certified by the Canadian Welding Bureau (CWB). In contrast, in the USA, they are accredited by the American Society of Mechanical Engineers (ASME), the American Welding Society (AWS), and the American Petroleum Institute (API), among other prestigious organizations worldwide. A CWEng is responsible for designing and selecting the appropriate welding parameters, which include plate beveling, wire and flux specifications, amperage, voltage, and welding speed, among other factors.
Irizar does not offer training, as the machine is straightforward to operate. However, it must be operated by an experienced Submerged Arc Welding (SAW) Operator. Certification is required for this trade, meaning the operator holds a certification as a journeyperson. Irizar rental facility is available in Wetaskiwin, AB, Canada, where customer welder operators can familiarize themselves with the equipment and obtain coupons for qualifying Welding Procedure Specifications (WPS), Procedure Qualification Records (PQR), and Welder Qualification Tests (WQT). Otherwise, we recommend purchasing the machine in advance and making it work in your shop before setting it up on the jobsite
