The sourcing platform buyers use to find verified welding suppliers, indexed by process, certification, and material. Free to start.
Welding is one of manufacturing's most specification-driven, skill-dependent processes. Finding a supplier who is actually certified to your weld procedure and has experience with your material is not something you can figure out from a website. TandemOne gives buyers a better way. Our platform profiles verified welding and joining suppliers by process (MIG, TIG, laser, friction stir, robotic), material capability, weld certifications, and industry experience, so you can identify qualified weld shops before you share a drawing.
TandemOne captures weld certifications (AWS D1.1, ASME Section IX, MIL-STD), process capability, and NDE methods so you can filter for suppliers already qualified to your specification.
Find a robotic MIG shop for high-volume structural frames, a TIG specialist for precision aerospace assemblies, or a laser welding supplier for hermetic sealing. TandemOne makes the distinction.
Provide your base material, joint configuration, applicable code, and volume in one RFI. Suppliers respond with real capability, not a generic confirmation.
