Failure analysis of conveyor chain links: a case study at Top Glove Sdn. Bhd.

This case study is to investigate the causes of failure of chain system through characterization on the failure component. The failures that occur are relate to welding because this dipping latex industry use customized chain that have to be welded at joining with outer chain links. The analysis rev...
