Concept of Laser Welding of Concentric Peripheral Lap Joint

Abstract. This paper presents the concept of concentric peripheral joint. Designed joint was projected to laser welding process, where using keyhole effect deep penetration trough three materials presented. Concept includes elastic stainless steel material as an connector between two pipes. Stainless in form a ring used additional distance element, joined with Presented investigated numerical simulation based on finite element method Simufact Welding software. Performed investigation possibility single and double beam welding. included sealed joint, only partial bottom obtained full [1]. The authors presented comparative study joints parameters for assumed were estimated via simulations [2]. lap shows pass geometry [3].
