Recommendations for Improved Welding Procedures for Thick Steel Plates Through Thermo-Mechanical Analysis

Dimitrios Lignos

Welding of steel plates is accompanied by residual stresses that increase as the constraint provided by the welded components becomes greater. Consequently, crack initiation has been reported after welding thick plates due to the high residual stresses dev ...

Influence of the optical measurement technique and evaluation approach on the determination of local weld geometry parameters for different weld types

Alain Nussbaumer, Martin Antonio René Garcia

The joining by welding processes of components is usually related to the creation of additional notches and geometrical peculiarities. Multiple investigations have shown that a clear correlation between the local weld geometry and the fatigue life of welde ...

Interface microstructure formation of dissimilar Fe/Fe-Mn-C steel RSW joints

Léa Deillon

An experiment was developed to simulate the interface between liquid high manganese carbon steel and solid ultra-low alloyed steel in a thermal gradient, corresponding to the nugget/sheet interface of resistance spot welds. Despite the large difference in ...

Robotic Assistance by Impedance Compensation for Hand Movements While Manual Welding

Aude Billard, Mustafa Suphi Erden

In this paper, we present a robotic assistance scheme which allows for impedance compensation with stiffness, damping, and mass parameters for hand manipulation tasks and we apply it to manual welding. The impedance compensation does not assume a preprogra ...
