Dove-tail Joints in Steel
H. K. D. H. Bhadeshia
The strongest and most permanent right-angled joints made in wood are the 'dove-tail' joints, as illustrated below. The so-called tails and pins fit together to form a secure joint. Glue may be applied to the mating surfaces.
We demonstrate here that large sections of steel can be joined mechanically, using dove-tail joints of the type typical in wooden furniture. Most of the photographs below were taken at an art exhibition in San Sebastien, Spain. Some of the exhibits weigh many tonnes. The last one is from a similar exhibition in South Korea.
