Fig. 1. Experimental Setup: (a) Schematic diagram of the hybrid laser-GMA welding system; (b) Hybrid laser GMA welding system. Material and experimental design In the lap joint weld trials, a hot-rolled AISI 1018 carbon steel sheet having a size of 400 mm × 70 mm × 1.6...
Schematic diagram of Al/Cu medium-thick joint produced by DS-FSZW Full size image After welding was completed, using the electrical discharge machining to cut the tensile specimens, OM samples and EBSD samples, which were shown in Figure2(a). The tensile sample adopted the GB/T 228.1-2010 ...
In this study, lap joint laser welding was performed on 5182 and 6061 dissimilar aluminum alloys. Mg and Si contents in the two aluminum alloys have an obvious difference (4.5 wt% Mg and 0.08 wt% Si in 5182; 0.94 wt% Mg and 0.58 wt% Si in 6061) [3,11]. The other elemental conten...
Pure zinc foil was selected as an interlayer to improve the strength of the AZ31B Mg/7075-T6 Al dissimilar alloys friction stir lap welding joint. Compared with the conventional lap joint, the joint with the zinc interlayer has a higher effective sheet thickness, a larger effective lap width ...
The method for predicting a fatigue life of the laser lap-welded joint comprises: an analysis model preparation step of preparing an analysis model 5 of a laser lap-welded joint 4; an elastic structure analysis step of calculating a stress by performing an elastic structure analysis on the anal...
