This *pipe/plate has been examined to the requirements of code/specification TWI-N/WIS-PI ......................................... and is accepted/rejected accordingly. Comments: * Request MPI testing to confirm crack and length. ** Large amount of spatter on weld face. Recommend this is removed and re inspected. *** Recommend arc strikes are ground flush prior to MPI testing for cracks.
