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

EN ISO 16433:2007 (ISO 16433:2006 adopted by CEN) specifies a procedure and requirements for resistance seam welding of uncoated and metallic-coated low carbon steels. It applies to assemblies of two sheet components where the maximum single-sheet thickness is 0.4 mm to 3 mm. Covered surface types include uncoated steels and metallic coatings such as hot-dip zinc/galvannealed, electrolytic zinc/zinc-iron/zinc-nickel, aluminium-coated, and zinc‑aluminium steels. Organic- or primer-coated steels are excluded.

Key Topics

Scope and applicability: Seam welding of two-sheet assemblies of low carbon steel (0.4–3 mm), listing applicable coated and uncoated surface conditions.

Process types: Continuous-current seam welding and interrupted-current (pulsed) seam welding; also describes mash seam, wire seam and wide-electrode seam techniques.

Welding equipment and electrodes: Guidance on welding machine characteristics, electrode (wheel/mandrel/pad/backing bar) materials, dimensions and cooling requirements.

Materials and surface preparation: Requirements for flat-rolled steel form, acceptable surface conditions, and limitations on coatings.

Weldability and procedure development: Methods to determine weldability lobes and to select welding parameters adapted to machine and production conditions.

Type and routine testing: Mandatory test methods include manual peel, mechanised peel, pressure tests, metallurgical and visual examinations, and geometric weld measurements. Acceptance criteria and failure-mode assessment are defined.

Quality control and production: Routine checks for nugget width, weld dimensions, appearance, failure modes and distortion; guidance for reclaiming non-conforming assemblies.

Informative annexes: Annex A (equipment guidance), Annex B (typical seam welding conditions), Annex C (partial list of applicable steel grades).

Applications

Who uses EN ISO 16433:2007:

Welding engineers and procedure writers developing welding procedure specifications (WPS) for seam welding.

Quality managers and inspectors performing routine weld testing (peel, pressure) and acceptance checks.

Fabricators in industries that seam-weld coated or uncoated low carbon sheet: automotive body panels, white goods/appliances, HVAC ducting, light-gauge construction, and general sheet-metal manufacturing.

Machine manufacturers configuring equipment (wheel electrodes, cooling, controls) for consistent resistance seam welding production.

Practical value: ensures repeatable, verifiable seam weld quality for coated/uncoated low-carbon steels, assists compliance with industry-specific WPS and helps reduce production defects from poor electrode choice, incorrect parameters or unsuitable surface conditions.
