Background
The fixture determines the quality of the seam
A significant proportion of weld irregularities are not caused by incorrect welding parameters, but by a component that deviates from its specified condition. No matter how precise the welding procedure is — if the component is positioned differently in every cycle, the result will vary.
For designing and fixture construction, this means that clamping, positioning and accessibility are quality-critical decisions, not a minor matter.
- 01 Root gap and rib spacing vary across the range
- 02 Edge misalignment due to parts not being centred
- 03 Forced position instead of the WPS-qualified position
- 04 Clamping devices cover the seam and the inspection access point
