Job ticket that moves physically with the parts and gets signed or stamped at each station: receiving, wash, load, cycle start, at heat, quench, temper, hardness check and final inspection. It is the raw record behind the cert and the first thing pulled when a lot goes bad. Missing entries on a traveler are a routine audit finding.
Write the at-heat time on the traveler, not on your glove, the auditor's here Thursday.
