What does the D1.5 workmanship section cover?: Base metal preparation, fit-up, weld profiles and corrections.AASHTO/AWS D1.5M/D1.5:2020, workmanship (section number not confirmed)
A root opening measures outside the WPS tolerance. What happens?: Welding on that joint waits. The opening is corrected under the workmanship rules, with the Engineer's acceptance where the code requires it.AASHTO/AWS D1.5M/D1.5:2020, workmanship: fit-up and corrections (section number not confirmed)
Against what is a fit-up measurement judged?: The WPS and the code's workmanship tolerances. Never shop habit or the last job.AASHTO/AWS D1.5M/D1.5:2020, workmanship: fit-up (section number not confirmed)
Where do you look for rules on laminations found at a cut edge?: The workmanship section, in the base metal preparation provisions.AASHTO/AWS D1.5M/D1.5:2020, workmanship: base metal preparation (section number not confirmed)
What should be recorded when a fit-up problem is corrected?: The measured value, the correction made, and who accepted it.AASHTO/AWS D1.5M/D1.5:2020, workmanship; inspection records (section number not confirmed)
Where are the rules on the shape of a finished weld?: Weld profiles are in workmanship. Acceptance of the finished weld is in the inspection section.AASHTO/AWS D1.5M/D1.5:2020, workmanship: weld profiles; inspection: visual acceptance (section number not confirmed)
What decides minimum preheat under D1.5?: The steel, its thickness and the hydrogen level of the consumable. Read the technique section.AASHTO/AWS D1.5M/D1.5:2020, technique: preheat (section number not confirmed)
Where and when is preheat measured?: At the distance from the joint the code states, before the arc starts, and kept during welding.AASHTO/AWS D1.5M/D1.5:2020, technique: preheat and interpass (section number not confirmed)
The joint cools below preheat during a break. What now?: Reheat to the required temperature before the next pass. Preheat applies throughout welding.AASHTO/AWS D1.5M/D1.5:2020, technique: preheat and interpass (section number not confirmed)
Why may D1.5 set a maximum interpass temperature for some steels?: Too much heat can harm the properties of some bridge steels, so a maximum may apply as well as a minimum.AASHTO/AWS D1.5M/D1.5:2020, technique: interpass temperature (section number not confirmed)
Why might heat input be limited on bridge work?: High heat input can lower toughness in the heat affected zone.AASHTO/AWS D1.5M/D1.5:2020, technique: heat input (section number not confirmed)
Low-hydrogen electrodes passed their exposure limit. What happens?: They come out of use until they are redried or discarded as the code's consumable rules direct.AASHTO/AWS D1.5M/D1.5:2020, technique: consumable storage and exposure (section number not confirmed)
