Dimensional and geometrical tolerances
We check the part against the tolerance classes of EN ISO 13920 and, in structural work, against the essential and functional tolerances of EN 1090-2: lengths, angles, straightness, flatness and squareness. Whatever is not dimensioned on the drawing still has a tolerance, and that is precisely where most disputes start.
Checks before welding
A good share of the deviation is already there before the arc is struck: edge preparation, root gap, misalignment and plumb of the assembled part. Measuring at this stage costs an hour; measuring at the end costs a rebuild.
Distortion monitoring
We measure before, during and after welding to quantify how much each sequence moves the part. With that data the welding sequence gets corrected or pre-setting is defined, instead of straightening afterwards and introducing stresses nobody allowed for.
First Article Inspection
Full verification of the first part of a run against drawing and specification, with the record the client needs in order to release the rest of production.
Dimensional report
We hand over the measurements taken, the criteria applied and the decision, with deviations located on the drawing. It is a document that works equally well to release a part or to make a claim.
