D14.1-1985 SPECIFICATION FOR WELDING OF INDUSTRIAL AND MILL CRANES AND OTHER MATERIAL HANDLING EQUIPMENT (PHOTO COPY ONLY)

Member Price: $138.00

Non-Member Price: $184.00

Overhead cranes and material handling equipment that utilize plate girders and other welded plate structures rather than the rolled beams normally used in fabricating steel for bridges and building are described. The equipment covered by this specification also includes rotating equipment and movable components which can induce vibration and moving loads to the structure. These conditions and the associated fully reversible loading result in large numbers of load cycles in a relatively short period and local bending stresses of significant levels. The above items have significant effects on the selection of base and filler metals, weld selection and joint design. A qualification procedure for welding operators engaged in long run operations involving closely controled procedures and welding conditions and repetitive welds based on results of welds produced under the specific existing conditions is also described.
