Welding Challenges in Steel Pole Transmission Structure Connections

The fabrication of slender tapered steel transmission pole structures often requires challenging welding procedures in complex details involving longitudinal seam welds, fillet welds, complete joint penetration (cjp) and partial joint penetration (pjp) welds in connections, splices and base plates. This paper will review some of the challenges in successfully executing these welds and welding procedures as witnessed in shop inspections. In this white paper, a comparison is made between several common welding methods as found in practice and recommendations will be suggested to help ensure performance under the challenging environmental and loading conditions in these structures.
