Orbital Welding Solutions

Arc Machines offers a complete range of power supplies/controllers—from portable units to production-volume workhorses—as well as weld heads to meet every GTAW need and a comprehensive line of accessories to maximize equipment performance and efficiency. Applications for our products and systems include:

  • Butt welding with filler wire for austenitic, duplex and super duplex stainless steel, and titanium.
  • Fusion butt welding using liquid-cooled weld heads for high-production usage and heavy-wall applications.
  • Narrow groove welding to reduce hoop shrinkage and residual stresses for thick-wall pipes and vessels.
  • Socket/fillet welding that maintains the tungsten angle in line with torch movement.
  • Tubesheet welding using automatic orbital fusion or wire-feed for flush, recessed, or projected tubesheet configurations.
  • Fixtured welding using computerized controls for weld head positioning and travel.
  • Weld overlay or cladding for corrosion and wear resistance.
  • ID welding/cladding where pipe welded outside a vessel is clad with corrosion-resistant filler to match cladding used on the ID of the vessel.
