The effects of geometrical and process variables on the quality of cast-on-strap joints
- Pasminco Research Centre, Boolaroo (Australia); and others
An automated laboratory scale cast-on-strap joining process has been developed which allows tight control of relevant casting parameters such as strap mold and metal temperature, lug immersion speed and the time between strap filling and lug entry into the molten strap. The joining of lead-antimony and lead-tin strap alloy with lead-antimony and lead-tin strap alloy with lead-antimony and lead-calcium-tin lugs has been studied. It has been found that lead-tin is not suitable as a strap alloy for alloy combinations and joining conditions investigated. Penetration depth of the lug into the strap has been found to be critical and may be optimized for a given lug thickness under fixed process conditions. The joint quality improved with a deeper penetration of the thicker lugs for the geometrical configurations studied in this work. It is far easier to form a sound joint with thin lugs as these are not as sensitive as thick lugs to variations in the joining conditions.
