Abstract : Description and results of test for detection and measuring of underbead cracks in welding of high-tensile steels and the effects of chemical and physical properties and welding conditions upon the formation of the cracks. It was found that cracking increased with thickness up to about one inch, and then decreased with further increases in thickness. Cracking also increased with increase of carbon and manganese. No correlation was observed between cracking and tensile strength, plate hardness, and heat input within the welding ranges used. (Author)
