ISO 18278-2:2016 provides specific test procedures for the determination of the acceptable welding current range and the electrode life. It is applicable for the evaluation of the weldability of assemblies of uncoated and coated sheets of individual thicknesses from 0,4 mm to 6,0 mm.
Abstract
Overview
ISO 18278-2:2016 - Resistance welding - Weldability - Part 2: Evaluation procedures for weldability in spot welding specifies laboratory test procedures to determine the acceptable welding current range and electrode life for resistance spot welding. It applies to assemblies of uncoated and coated sheets with individual thicknesses from 0.4 mm to 6.0 mm and is intended to characterize the effects of electrode design, material, cooling and welding equipment on spot weld quality.
Key topics and technical requirements
- Scope and purpose: Defines procedures to evaluate weldability in spot welding by measuring welding current range and electrode life.
- Welding equipment & electrodes:
- Welding current and control:
- Specify AC or DC; use constant current control.
- For AC equipment, welding current shall be at least 30% of RMS value at full conduction angle.
- Mechanical settings:
- Limit electrode impact (recommend approach speed 0.15 m/s and/or peak force
