Overview
ISO 5183-1:1998 specifies dimensional and designation requirements for electrode adapters (electrode extensions) with a male taper 1:10 used in resistance welding (spot welding). Part 1 covers the conical fixing, taper 1:10, defining types, dimensions, tolerances and marking so that replaceable electrode tips and holders are mechanically and electrically interchangeable.
Key topics and technical requirements
- Scope: Dimensions and tolerances for electrode adapters (commonly called allonges) with removable tips where the adapter uses a male 1:10 cone and the conical shank conforms to ISO 1089.
- Types: Defines types A, B and extended/long cone type C (type C intended for use when electrodes are mounted at an angle).
- Dimensional data: Detailed dimension tables (Table 1 and Table 2) for typical diameters (for example d = 13, 16, 20 mm) and a range of lengths; surface roughness and cone diameter at the gauge plane are specified.
- Materials: Adapters shall be manufactured from materials conforming to ISO 5182 (preferably group A, type 2).
- Designation and marking: Prescribes a standard designation format (e.g., ISO 5183-1 - A - 16 · 58 - A 2/1) and the required marking format for parts (short form such as A - 16 · 58 - A 2/1).
- Annexes: Informative Annex A provides recommended dimensions for flats to assist removal with tools; Annex B gives bibliographic references.
- Interchangeability: Notes compatibility with electrode holders conforming to ISO 8430-1/2 and the cone forms in ISO 1089.
Practical applications and users
Who benefits:
- Welding equipment manufacturers and OEMs specifying electrode adapters for resistance welding machines.
