However, the dissimilar fusion welding of IN-718/MSS-410 is challenging due to the differences in thermal expansion coefficient, physical and mechanical properties of base metals. In this study, the solid-state vacuum diffusion bonding (VDB) technology is employed to develop the dissimilar IN-718/MSS-410 joints. The aim of this study is to find the optimal combination of VDB parameters such as diffusion bonding pressure-DBP (MPa), diffusion bonding temperature-DBT (°C) and diffusion bonding time-DBt (min) for enhancing the strength of IN-718/MSS-410 joints. The response surface methodology (RSM) was integrated for designing the experimental matrix. The strength performance of VDB joints was evaluated by conducting the lap shear strength (LSS) and bonding strength (BS) tests. The mathematical LSS and BS predicting models were established using regression analysis and verified employing the variance analysis. The microstructural features were analyzed using optical and scanning electron microscopy (SEM). The X-ray diffractometer (XRD) was employed to identify the phases evolution in the joint interface. The experimental results revealed that the IN-718/MSS-410 joints diffusion bonded using the DBP of 14 MPa, DBT of 960 °C and DBt of 90 min exhibited the greater LSS of 280 MPa and BS of 373 MPa. The prediction models accurately predicted the LSS and BS of IN-718/MSS-410 joints within 2 % error at 95 % confidence. It is primarily concerned with developing the optimal bonding width with the fewest possible embrittlement implications and better joining interface coalescence. According to variance analysis, the DBt was the most significant parameter influencing the LSS and BS of joints followed by the DBP and DBT.</p></div>","PeriodicalId":34313,"journal":{"name":"Journal of Advanced Joining Processes","volume":null,"pages":null},"PeriodicalIF":4.1,"publicationDate":"2024-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S266633092400030X/pdfft?md5=591edf36dbe2a4ba45a67adb8f5b9637&pid=1-s2.0-S266633092400030X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140133919","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditionally, the number of revolutions is constant in the RFW. However, rare investigations focus on the fatigue specimen fabricated by RFW with variable rotational speed. This study used RFW with varying rotational speeds to fabricate fatigue specimens. The ANSYS software was used to predict the temperature history of rotary frictionally welded dissimilar polymer rods fabricated by a computer numerical control (CNC) turning machine with variable rotational speed. The RFW experiment of ABS/PC dissimilar polymer rods was conducted to investigate the temperature history and compared with the simulation results. It was found that the temperature history profiles were in good agreement with the experimental and simulation results. Compared with the weld interface heating rate obtained from the experimental results, the simulation results has average discrepancy rate about 4.48 %. Compared with the maximum temperature of the weld interface obtained from the experimental results, the simulation results has average discrepancy rate about 3.16 %. The fatigue life can be increased by approximately 1.4 times.

An appropriate polymer joining technique can be used as a post-fabrication step to circumvent this issue. This paper explores the findings related to the joining of MEX-3D printed parts fabricated from generally preferred thermoplastics, Acrylonitrile Butadiene Styrene (ABS), and Polylactic acid (PLA) by the Spin Friction Welding (SFW) technique. The critical parameters involved in the process are identified and optimized using statistical tools including Design of Experiments (DOE), Taguchi, and Analysis of Variance (ANOVA). The results revealed that the type of material combination as well as the number of perimeter shells had the highest effect on the joint strength and cylindricity of the welds, resulting in the joint efficiency going up to 93.16 %. The practicability of the research was further approved by implementing the results to weld the sections of a service saddle point of a pipeline, wherein the weld displayed good strength and integrity.

USMW is particularly surface-sensitive, but to date no generally valid surface parameters are known for characterizing the weldability of parts and components. Component cleaning before the process is common, but to achieve consistent quality, the cleaning process must be adapted to the condition of the uncleaned component and to the desired surface. In industrial applications, cleaning has so far often been carried out using costly and comparatively environmentally harmful processes based on mechanical and chemical principles. Within this study we investigate prior treatment of copper workpieces for USMW by means of laser beam and compare the results with chemically and mechanically processed samples. Laser treatment of the typically bright copper surfaces (low radiation absorption in the infrared range), remaining organic residues and the new formation of oxide layers pose significant challenges developing a robust process chain. Different laser treatment strategies are compared and evaluated for different initial surface conditions. The influence on the resulting cleaned surface properties, the resulting USMW process and the joint quality thus achieved is experimentally evaluated. An analytical approach to assessing the weldability based on surface properties and surface treatment is derived. The correlation of surface properties of the materials used, the welding process and welding results is possible. The lowest surface roughness and removal of rolling grooves results in the most efficient welding process. The use of laser treatment leads to the desired alignment of different input conditions, which is also represented in the robustness of the welding result.
