Acceptance criteria for electroslag weldments in bridges
The research was conducted to develop acceptance criteria that can be used by highway engineers and transportation officials to assure that electroslag weldments when made by controlled procedures under production conditions are suitable for use in tension members of bridges fabricated from approved structural steels with minimum yield points up to 50 ksi (345 MPa). A literature search was made and extensive studies were conducted using laboratory specimens of electroslag weldments of the type used in full-size bridge girders. These tests included nondestructive examination, thermal distribution, macro- and micro-examination, residual strain, hardness, chemical, weathering, tension, fatigue-crack growth rate, and a wide variety of fracture toughness. Full-size girders of A36 and A588 steel with thickness transition joints were fabricated and subjected to fatigue loading followed by impulse loading at low temperatures. The data show that adequate strength, ductility, and notch toughness for AASHTO Zone 1 and Zone 2 service can be obtained with commercially available filler metals and procedures. Tentative acceptance testing procedures are suggested. (Kursetz)
