Up Topic Welding Industry / Technical Discussions / Charting multiple welds with one thermal couple
- - By sharloff Date 02-29-2008 09:28
Does any one know what/if the code requirement is for thermal couples when PWHT butt welds. example: can a shop "split" one lead 3 ways and then use one thermal couple on one weld to chart those 3 welds? If possible please reference code.I do know some client specs do not allow this type of set up, just wondering if there is a code restriction.
Thanks!!

Personally, and only speaking for myself, I won't even bother checking the Code on that one, it's just p*ss poor practice and very ill advised.
