Abstract
In this thesis, the objective is to study the joining strength based on different joining technique. The focus objective joining strength in this thesis is the spot welding and the adhesive bonding. This technique need to study the effectiveness of the spot welding and adhesive bonding used to join the car body parts and strength of this method need to be analyses. The method used in this thesis are used the five different material with combination with specimen A and A, B and B. The joining used are spot weld and adhesive been applied with the different thickness in 0.65 mm, 0.7 mm and 1.0 mm. the type specimen used are SPCUD 35, SPC 440, PR SPCD, SPCD 440, and INR SPCD. To study the strength of these method, tensile test have been conducted. The experiment been conducted by load vs displacement and strength vs material. The experiment findings showed those spot weld and adhesive bonding with same material shows different strength and also different effect to the parent material. Spot weld bonding will affect the microstructure of specimen and been harden the bonding of joining spot weld. When the force applied higher than strength of the joining, the resistance area around nugget of spot weld start to crack and failure happen at around the nugget itself not at nugget welding. The strength of the spot weld is depending on the strength of material and thickness of material applied to the joining. The strength of adhesive bonding is depending on type of adhesive and surface roughness of the material itself. The shear test shows the adhesive bonding have an average 5.43 MPa and spot weld joining is 6.79 MPa not much different Based on experimental result, adhesive bonding is applicable for automotive body joining.
