ISO16433:2006 specifies requirements for resistance seam welding in the fabrication of assemblies of uncoated and metallic coated low carbon steel comprising two sheets of metal, where the maximum single sheet thickness of components to be welded is within the range 0,4 mm to 3 mm for the following materials: uncoated steels; hot-dip zinc or iron-zinc alloy (galvannealed) coated steel; electrolytic zinc, zinc-iron, or zinc-nickel coated steel; aluminium coated steel; zinc-aluminium coated steel.

Overview

ISO 16433:2006 - Resistance welding - Procedure for seam welding of uncoated and coated low carbon steels specifies requirements and guidance for resistance seam welding of two-sheet assemblies made from uncoated and metallic-coated low carbon steels. The standard applies where the maximum single sheet thickness is 0.4 mm to 3 mm, and covers materials such as uncoated steels, hot‑dip zinc (galvanized/galvannealed), electrolytic zinc/zinc‑iron/zinc‑nickel, aluminium‑coated and zinc‑aluminium coated steels. Organic‑coated or primer‑coated steels are excluded.

Key topics and technical requirements

Materials and surface condition: Steel must be flat‑rolled and free of contaminants (grease, scale, paint, corrosion). Thin phosphate pre‑treatments and some passivations are allowed with parameter adjustment.

Process types: Defines continuous‑current and interrupted‑current seam welding and other seam processes (wide/thin wheel, mash, wire, wide‑electrode, foil).

Component design: Requirements for flange width, electrode access, edge distance and joint geometry to ensure consistent weld formation. Notes on pitch: minimum centre‑to‑centre distance between parallel seams is 16 × sheet thickness (t); for t ≤ 1.5 mm the inter‑weld pitch ≈ 3 × tread width (W).

Welding equipment and electrodes: Guidance on machine capabilities, electrode materials, dimensions and cooling to suit process and coated surfaces (see Annex A).

Weldability and qualification: Procedures for weldability assessment and establishing welding parameters (welding lobes, parameter windows).

Testing and acceptance: Type tests (peel, mechanized peel, pressure, metallurgical assessment), routine tests and quality‑control checks covering weld dimensions, nugget width, failure modes, surface appearance and distortion.

Non‑conformance: Reclamation procedures for assemblies that do not meet requirements.

Practical applications

ISO 16433 is intended for manufacturers, welding engineers and quality managers involved in:

Automotive body-panel fabrication and assembly

Appliance and HVAC sheet‑metal fabrication

General light‑gauge steel assemblies where continuous or intermittent seam welds are used The standard helps ensure repeatable seam weld quality on coated and uncoated low carbon steels, improving joint integrity, corrosion protection retention and production efficiency.
