Abstract Scope |
Automotive heavy body parts used in vehicles lead to high fuel consumption. Ozaki and Kutsuna, [1], resolved the issue of weight by replacing some steel component by aluminium which is lighter. Joining steel to aluminium, which have vast thermal mismatch, is met with difficulties which include intermetallic formation. In this paper laser welding of 1.2 mm Al 5754 series to 0.8 mm Zn coated steel was used to lap joint using linear energy output of 18-30 kJ/m. The welds were first inspected for surface defects using stereo-microscope and crack-free samples were metallurgical prepare for characterisation. The results show that samples with deeper penetration had low shear strength than samples with shallow welds. |
