It is essential to achieve highest quality of weld such that weld is as good as parent metal Problems in welds can be classified as Imperfection Any deviation from the ideal weld Defect An unacceptable imperfection Weld acceptance standards Classification of imperfections according to BS EN ISO 65201 This standard classifies the geometric imperfections in the Dec 12 2003 A case in point is grinding a part on a Blanchard Grinder going from rough to flat and parallel When the surface clears you make a very small adjustment on the infeed and let it spark out This is to average out any imperfections caused by the grinding wheel or machine This is more of a concern with solid wheels than on segment wheels
