The results are reported of static tension tests and impact bend tests on studs and push-out tests on stud shear connectors with the stud welds made on bare steel and through 20 and 18 gage (0.953 and 1.27 mm) wipe coated galvanized decking at temperatures ranging from 20 to −40 °C. Welding procedures, qualified on the basis of static tension tests, are developed for welding studs over this temperature range. Increased heat input is required to obtain satisfactory welds, both for decreased temperature and increased thickness of galvanized decking. Impact bend tests do not provide a satisfactory criterion for the rejection of stud welds in the field at temperatures below −5 °C. The angle of bend is a function of the test temperature and not the temperature at which the qualified weld was made. Static tension tests at room temperatures form an adequate basis for qualifying stud welding procedures.
