Weld Defects - Lack of Sidewall and Inter-Run Fusion - TWI

Weaving,especially dwelling at the joint sidewall,will enable the weld pool to wash into the parent metal,greatly improving sidewall fusion.It should be noted that the amount of weaving may be restricted by the welding procedure specification limiting the arc energy input,particularly when welding alloy or high notch toughness steels.Weld Defect - an overview ScienceDirect TopicsLack of side wall fusion Failure of weld metal to fuse to weld preparation Current too low,travel speed too high,incorrect torch angle,oxide film on prep.surfaces,inadequate joint cleaning,weld preparation too narrow 4012 (Fig.11.1) Lack of inter-run fusion Failure of weld metal to fuse to preceding runUL-142 Tanks Modern Welding - Steel Storage Tank Vertical tanks may be of single or double wall construction.If the tank is a double wall configuration,then it has interstitial monitoring capabilities.These tanks may also be built with or without multiple compartments for multiple fuel storage.Tanks generally have flat bottoms and conical roofs.
