Joint preparation—ISO 9692

Joint preparation is the interface between design and welding technology. It controls arc access, root stability, filler volume, number of runs, distortion, NDT feasibility and sensitivity to assembly tolerance.

Topic overview

Joint preparation is the interface between design and welding technology. It controls arc access, root stability, filler volume, number of runs, distortion, NDT feasibility and sensitivity to assembly tolerance.

Is the selected preparation robust over the full production range of root gap, root face, offset and welding position?

Angle, gap and root face determine whether energy reaches the root.

Every unnecessary square millimetre multiplies into length, filler, time and distortion.
