    What Welding & Metal Joining suppliers provide

    Suppliers in this category join metal parts using MIG, TIG, spot, or specialised welding processes, alongside brazing and other joining methods where appropriate, to build fabricated assemblies and structures. Their core competence lies in matching welding process and joint design to the material, thickness, and structural requirements of the assembly. Many also provide fixturing, post-weld machining, and non-destructive testing. In the pre-selection phase, compare which materials, welding processes, and certifications each supplier holds rather than individual equipment lists.

    Relevant standards

    Quality requirements for fusion welding of metallic materials follow ISO 3834. Steel and aluminium structural fabrication follows EN 1090, which applies particularly to load-bearing structures. Supplier quality management is typically certified to ISO 9001.

    Frequently asked questions

    Which certification should a structural welding supplier hold?
    ISO 3834 covers quality requirements for fusion welding generally, while EN 1090 governs the execution of steel and aluminium structures, including CE marking requirements, and is relevant when the assembly is a load-bearing structural component.
