Linear weld density
Nettet90 the weld interface to the entire weld along the weld interface was termed as linear weld density 91 and it was used as a quantitative weld quality criterion for ultrasonic welds. Hu et al. [29] 92 proposed peel test to analyse bond quality. The higher strength, a material offered during 93 peeling it off from the weld, represented the higher ...

NettetThe linear weld density results show that the sample was formed with high weld density. A microstructural and EDX study confirms the … Nettet25. jun. 2024 · Although resistance spot welding (RSW) was invented at the beginning of the last century, the online-monitoring and control of RSW is still a technological challenge and of economic and ecological importance. Process, material and geometry parameters of RSW are stored in the database of the process control system. Prospectively, these …
NettetGonzalez et al. [5] used thinner SS 316L foils to achieve steel foil-to-foil bonding via UAM and identified the optimum parameter set for welding SS 316L based on optical images and linear weld density. However, no mechanical properties of UAM-fabricated SS 316L builds were provided in this research. NettetIt can be used in welded construction at service temperatures of up to 600° F. Titanium 6AL-4V alloy offers its high strength at a light weight, ...

Nettet1. aug. 2014 · The quality of the components has been often evaluated by the linear weld density, which is defined by the ratio of the welded to the total interface length at a selected cross-section. Kong et al. developed a process window of the UAM process on the basis of the weld strength obtained by peel tests [2], [3]. NettetLinear weld density is also discussed in a separate paper in these proceedings [5]. However, this direction of build allows the entire rib to be entirely created from a single tape, so issues that arise from having tapes laid next to each other,
NettetAn asperity layer model based on sinusoidal shape solid asperities is proposed to associate the plastic deformation of the material to the linear weld density of the bonding at the interface. Other sub-models (thermal and friction models) are defined based on studies in the literature.
