“…Weld trajectories along contact lines were determined. Simulations of welding were conducted for S235JR and 316L steels and a materials library with parameters dependent on temperature (calculated https://doi.org/10.37705/TechTrans/e2021030 using JMatPro software) was used (Phanikumar, 2011). Numerical simulation for both analysed joint were performed (Fig.…”

This article presents a numerical analysis of laser-welded flange pipe joints. The presented results concern the welding of low carbon S235JR and stainless 316L steels using a CO2 laser in lap and fillet joint configurations. The estimation of welding parameters was achieved using Simufact Welding software and numerical simulation, where output power, feed rate, efficiency and intensity distribution (Gaussian parameter) were analysed. In accordance with the established model, a thermo-mechanical simulation was performed. The calculated joint geometries show good agreement with experiments; therefore, the obtained results were used to study selected joint properties of both joint types. Stress-strain distribution was estimated on the basis of thermomechanical analysis. Weld bead geometry obtained from numerical simulation was compared with the results from trial joints. The numerical model established for both joint configurations shows good agreement with experimental results and were assumed to be accurate. The results of the performed analysis shown some advantages of the use of this configuration of lap joints in flange pipe joints.

“…Simulations of conventional arc welding use the double-ellipsoid Goldak model, however, simulations of laser welding are based on volumetric heat sources (conical and cylindrical), with uneven power distribution (Gaussian parameter). Moreover, some methods use a combination of HSs, with a conical (1) source for simulating the keyhole effect, and a disc-shaped source for simulating laser beam absorption by the material surface ( Figure 3 ) [ 27 , 28 ].…”

This paper presents the results of laser welding of dissimilar joints, where low-carbon and stainless steels were welded inthe lap joint configuration. Performed welding of austenitic and ferritic-pearlitic steels included a sealed joint, where only partial penetration of lower material was obtained.The authors presented acomparative study of the joints under different configurations. The welding parameters for the assumed penetration were estimated via anumericalsimulation. Moreover, a stress–strain analysis was performed based on theestablished model. Numerical analysis showed significant differences in joint properties, therefore, further study was conducted. Investigation of the fusion mechanism in the obtained joints wascarried out using electron dispersive spectroscopy (EDS) and metallurgical analysis. The study of the lap joint under different configurations showed considerable dissimilarities in stress–strain distribution and relevant differences in the fusion zone structure. The results showed advantages of using stainless steel as the upper material of a microstructure, and uniform chemical element distribution and stress analysis is considered.

“…This type of joint however required using advanced joining technology. Traditional arc welding methods indicated high temperature into elements which can lead to overheat welded materials and chance its properties [6]. Therefore, some advanced welding methods such as laser beam welding (LBW) can be used.…”

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