Abstract :
A new non-destructive method of testing welds by an electrical means has been developed which can be applied to welds made in the field as well as to those made in the shop. A reliability of 8 out of 9 welds tested, or 89 per cent, already has been obtained and gives good promise for the future. The method may be applied also to the finding of flaws in other homogeneous objects of magnetic materials.
