Seam Welding

Automated Longitudinal Seam Welding

Longitudinal Seam WeldingLongitudinal Seam Welding at Superior Joining technologies, Inc. is an automated process that produces full penetration welded seams in sheet metal components with the Gas Tungsten Arc Welding (GTAW) method.

  • Thicknesses range from .010” to .188”
  • Diameters from 2.00” to 48.00” (and beyond with special consideration) and flat sheet as well.
  • Lengths can vary up to 60.00” long.
  • Post-Weld Planishing is available as required.
  • Materials include, but are not limited to, carbon steel, stainless steel and aluminum.

Superior Joining Technologies is offering Longitudinal Seam Welding in combination with our well-established support services such as Certified Weld Inspection (CWI) in compliance with the AWS, as well as two Non-Destructive Testing processes fully NADCAP accredited by PRI. Let us provide Longitudinal Seam Welding of your roll-formed, flat sheet and strip materials, or let us form it for you here. We are ready to serve you with high level quality and rapid response times.

Circumferential Resistance Seam Welding

Circumferential seam weldingResistance Seam Welding is a process that joins two or more members of an assembly in a lap joint configuration by producing a series of overlapping resistance spots. It can be used in a circumferential, cylindrical application as well as flat assemblies. It has proven to be a valuable companion service to the rolling department here. Our system is most suited to use on stainless steel assemblies. Our process performs welding in compliance to AWS D17.2.

Sheet Rolling

Sheet rollingSheet rolling is a value-added service we offer in conjunction with our automated linear seam welding and circumferential resistance welding services to fabricate custom pressure vessels as used in aerospace applications. We can handle materials from 0.010" thick stock 60" wide, for diameters from 2.00" to 48."
