Heavy Duty Welding

Boardman is a leading metal fabricator in Oklahoma City, OK. With more than 1,000 qualified weld procedures, we are prepared to handle any heavy-duty welding specification to bring your custom fabrication to life. We are focused on continuous improvement and efficiency while maintaining the highest level of quality. Our welders are experienced in working with a variety of materials including stainless steel, carbon steel, nickel, and hastelloy.

Boardman has 40 different welding machines in-house including two circles submerged arc welding (SAW) machines that automatically weld nozzles in the shell. Contact us today to begin your welding project.

Our 40 welding machines allow one of seven welding processes. Some of these processes include:

SAW (Sub Arc): This process uses a solid electrode submerged in flux. When the wire touches the metal, current is passed through the wire and melts, or "welds", the joint together and the top of the weld is covered in flux. Sub Arc is most commonly used for long seams and round seams.

FCAW (Flux Core): Flux Core is a hollow tubular wire filled with flux. In this welding process, the flux comes out of the center of the wire and covers the top of your weld with "slag". Slag is a protective cover that helps keep the impurities out of the weld. Flux core is commonly used for nozzle insertion welds, skirts, and/or support clips and other attachments. Flux core is great for fillet welds. 

GMAW (MIG): This process uses a solid electrode. There is no flux, crust, or slag associated with this welding process. It only requires a shielding gas that protects the weld. Short circuit MIG is most commonly used for open groove root welding only- pipe to pipe, pipe to flange, or root welds. Spray mode is used for filling grooves, nozzle insertion welds, and fillet welds. Pulse mode is used for groove welding and attachment welding.

GTAW (TIG): This welding process uses a piece of tungsten that is inside of a "cup". A shielding gas covers the tungsten while welding. While the tungsten is "hot and arcing", the filler metal is dipped into the weld pool. TIG welding is good for root pass welding and groove welding on pipe.

SMAW (Stick): This process requires someone to manually put the electrode into a stinger and is one of the oldest forms of welding.

Strip Overlay:  This is a SAW or ESW process. At Boardman, we can use 30 mm, 60 mm, 90 mm, or 120mm wide solid flat wire for the clad restoration or overlay process.
