Irizar Heavy Industries Inc., based in Edmonton, Alberta, Canada, designs, manufactures, and supplies specialized Tank Welding Equipment for the construction, erection, and maintenance of field-erected welded storage tanks. Our equipment is designed for welding horizontal circumferential seams, vertical shell seams, tank floors, and annular plate-to-shell joints, providing solutions for both the Traditional Construction Method (Bottom-to-Top) and the Tank Jacking Construction Method (Top-to-Bottom). Irizar Tank Welding Equipment includes Automatic Girth Welders, Motorized Shell Buggies, SAW Welding Tractors, FCAW Welding Oscillator Tractors, and welding accessories for field tank construction.
Automatic Girth Welders
Automatic Girth Welder (AGW) is a self-propelled frame with variable speed that applies efficient circumferential Submerged Arc Welding (SAW) on Field Erected Tanks (Vertical Tanks). SAW is primarily used on carbon steels, stainless steels, and certain nickel alloys, enhancing productivity and consistently producing high-quality welds. The AGW reduces the manual welding process up to 25 times. The AGW comes with a Power Source, Welding Head, Welding Controller, Flux Belt and Flux Recovery System. Girth Welders are also known as 3 O'Clock Welder, Automatic Girth Welder, AGW Welding, Automatic Tank Welder and Soldadura Arco Sumergido.
Available models include:
Motorized Shell Buggy
The Motorized Shell Buggy or Boggie provides quick access to vertical and horizontal welding seams on API field-erected tanks, eliminating the need for scaffolding. It facilitates welding inspections, repairs, and removal of tank fitting tools. It also allows the installation of FCAW welding oscillators for vertical welds. The Shell Buggy is compatible with the Traditional Construction Method [Down to Top] and the Tank Jacking Construction Method [Top to Down]—brochure page 19. The Shell Buggy is also known as a Self-Propelled Basket, Platform Shell Buggy,Shell Work Platform Buggy or Shell Boggie.
SAW Welding Tractor
SAW Welding Tractoris 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, and Lincoln LT-7 Tractor.
FCAW Welding Oscillator Tractor
The Welding Oscillator Tractor is used to apply vertical or circumferential flux-cored arc welding (FCAW) on steel tanks or pipes. Available in two options: a) Model 3000 applies FCAW on vertical seams on API Tanks up to 3,000 mm in length or pipes over 1,000 mm in diameter, and b) Model 150-1000 applies FCAW on pipes from 150 up to 1,000 mm in diameter. Available power source at extra cost. Welding Oscillator Tractor, also known as Welding Carriage, Welding Automation Carriage, Welding Oscillator Carriage and Track Welding Carriage with Oscillator.
Flux Belt & Accessories
Irizar also supplies Flux Belts and related components for Automatic Girth Welder systems.
The high-temperature-resistant Flux Belt is used during Submerged Arc Welding operations to support the welding flux around the circumferential tank seam.
CNC SAW Flange & Nozzle Welder
The CNC SAW Flange & Nozzle Welder is an automated circumferential Submerged Arc Welding (SAW) system designed for welding nozzles (pipe) and flanges with diameters ranging from 100 mm to 1,600 mm.
Applications:
• Pressure vessel-to-nozzle (pipe) welds
• Pressure vessel-to-flange welds
• Dished head-to-nozzle (pipe) welds
• Dished head-to-flange welds
