文摘

In the present study, a new-developed method which leads to the determination of the number of beads in the single-V butt weld joint, is introduced and applied to robotic Flux-cored arc welding technique. The correlation between the wire feed rate, the wire variables, the torch welding speed, and the bead reinforcement area is investigated and determined via a mathematical formula. The investigation includes a theoretical section where the method is analyzed and several confirmation experiments where the theoretical function of the bead reinforcement area is verified. Moreover, the method is applied to a multipass weld of steel plates with preselected welding parameters, through the determination of a proposed weld profile based on the fundamental principles, standards, and rules of the welding technology. The methodology can be also expanded in the case of multipass welding joints with a different edge preparation such as J, U, or double-V in butt and tee weld joints.
