Overview
The oSIST prEN ISO 1089:2021:2021 standard sets the specifications for electrode taper fits used in resistance welding equipment, specifically for spot welding applications. This standard defines the dimensions, tolerances, designation, and marking of taper fits for electrode caps, electrode adaptors, electrode holders, and similar components. It applies to electrode taper fits where the maximum electrode force (Fmax), related to diameter d1, is not exceeded, ensuring reliable mechanical and electrical connections during welding.
This revision cancels and replaces the earlier ISO Recommendation R 1089-1969, offering updated technical guidelines and improved precision in taper dimensions. The standard aligns with industry needs and supports consistent manufacturing quality and interoperability of resistance welding equipment parts.
Key terms: resistance welding, electrode taper fits, spot welding, electrode caps, electrode adaptors, taper dimensions, maximum electrode force
Key Topics
Scope and Application
The standard applies to electrode taper fits used in spot welding machines, covering three main taper types (A, B, and C) for various parts including electrodes and holders.Taper Dimensions and Tolerances
Detailed tables specify dimensions for each taper type:- Type A and Type B tapers relate to spot welding electrodes under straight and eccentric thrust conditions respectively.
- Type C tapers are used for electrode caps where no force is applied.
- Table 4 introduces precise taper dimension tolerances for type C tapers.
Designation System
The designation format includes the document number (ISO 1089), the taper fit type (A, B, or C), and the diameter d1 in millimeters. For example, "ISO 1089 - A 16" denotes a type A taper with a 16 mm diameter.Marking Requirements
Electrode holders manufactured in compliance with the standard must be marked with the taper type and diameter (e.g., A16) for easy identification and compatibility verification.Force Limitations
The standard defines maximum electrode forces associated with each taper diameter and type to ensure safety and performance integrity during welding.
Applications
