Q.As per cs no.3 if any flaw comes from front coller it should be confirmed by the other side but it will not confirmed by other side what should be do it is good weld or defective weld because mostly fracture occurs from the edge of the weld and we are marking defect after measuring at the centre of weld kindly give your suggestion.BY RR BHARATHI

A.If a signal is coming from near end collar (probing end ) it is definitely a flaw signal. However if a signal is coming from far end collar, this may be a flaw signal or coming from collar which may be confirmed from other end. BYY PANTH SIR RDSO
