Heavy Plate Fabrication

  • Heavy Plate Fabrication

heavy plate fabricationBoardman is a leading heavy steel plate fabricator for a variety of applications including petrochemical and marine. We fabricate steel plate using one of our four plate rolls to roll the plate into cylinders to fabricate pressure vessels, trayed towers, etc., or to bend and shear the plate to complete projects such as coke chutes or ducting. We have extensive experience with pressure vessel rolling and working with plate materials including carbon steel, stainless steel, clad material, nickel alloy, monel, Inconel and chrome moly. We also have experience with steel plate forming. 

Our heavy plate fabrication capabilities include:

  • A circle burner to burn holes in the plate
  • Two circle sub arc welding machines that automatically weld nozzles in the shell
  • 40 different welding machines
  • 1,000 welding procedures to weld almost any type of material

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 os 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 supports 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.

Our fabrication capabilities are endless and can span across industries including oil & gas, gas processing, cryogenics, chemical, petrochemical, aerospace, power generation, emission control, and carbon black. We can fabricate almost anything that’s up to 4” thick and 350 tons. We provide the highest quality according to the QA/QC department and standards.  Contact us today for your heavy plate fabrication needs.
