The self restraining Instrumented Restraint Cracking (IRC)‐test enables the determination of weld joint reaction forces and ‐moments responsible for hydrogen assisted cracking. With help of continuous measurements during cooling of the weld, the effects of crack inducing parameters can be detected in detail. The IRC‐test can be applied to procedure development and procedure qualification welding, making use of current fabrication practice at restraint intensities of the to‐be‐fabricated structure. It is easy to carry out and the results are quickly at hand.
