Development of seam tracking device in asynchronous tandem welding with arc sensing

Abstract: Tandem welding is extensively used for welding large structures, such as ships and plants, for increased welding speed and volume. Seam tracking is essential because of a large amount of thermal deformation. However, in tandem welding, arc interference causes current and voltage to vary non-uniformly, leading to difficulties in seam tracking. Therefore, in this study, an optimal signal was identified for seam tracking in tandem welding and evaluated. To select the seam-tracking signal, an algorithm was develop… Show more

“…While many welding processes are amenable to automation, automating the welding of large structures remains challenging. Productivity might suffer due to the thermal deformation of materials and the necessity of multiple passes [ 24 , 25 ]. To enhance deposition rates and welding speed in conventional welding processes, numerous studies have explored the benefits of tandem welding, which employs two arc heat sources.…”
