A satisfactory shop-type weldability test has been developed for measuring the field weldability of pipeline steels. It utilizes a 150 by 200 mm specimen removed from formed pipe, slotted centrally in the direction of pipe curvature, and welded by depositing the weld bead over the slot and extending 25 mm beyond each end of the slot. The test was used to study the extent of cracking as a function of time lapse up to 20 min after welding. Not only was there a strong effect of time, but some of the more sensitive steels developed cracks in less than 5 min. The effect of preheat on cracking was also clearly shown by the test. Thus the test appeared potentially useful for determining the time limit between the root pass and hot pass and the necessary preheat.
