Experimental investigation of Cu-SS electromagnetically assisted adhesive tube-to-tube joining: Its advantages over electromagnetic crimping
Source abstract
Abstract
Abstract Electromagnetically assisted adhesive joining (EAAJ) is a novel hybrid joining technique combining the benefits of electromagnetic crimping and adhesive joining. This paper explores the possibility of creating an interference-fit tubular adhesive joint with improved strength and leak tightness. An acrylic-based structural Loctite 638 adhesive is used. Experiments are performed with and without (electromagnetic crimping) adhesives. Pull-out and compression test is performed for both joining techniques which has confirmed a significant improvement in joint strength with adhesives. A two-factor ANOVA analysis is also performed to calculate the contribution of adhesives and discharge energy over pull-out and compressive strength of the joint. An air leak testing setup is developed to investigate the leak tightness of the Cu-SS tube-to-tube Joint. Leak tightness is observed to be increased by ten times in the case of EAAJ compared to EMC. Macrographs have revealed no metallic bond formation. Deformation analysis is also performed to study the various zones of the samples. Micro-hardness is observed to be decreased for the adhesive joint in the adhesive zone.
