摘要：
An experimental set-up for cold butt welding is developed. Before conventional upsetting of two specimens to be bonded, surfaces of the specimens are shaved off by an edge to bring out the virgin metal which is essential to cold pressure welding. Since the bulk deformation to form the virgin surfaces is smaller compared with the conventional process without using the edge, complete bonding is accomplished with a small strain in upsetting of the specimens. This result leads the following advantages of the present process. (1) Waste of the material which is used as a flash is reduced. (2) The upsetting load, i.e., the bonding load is lower.
