Bimetal plane bearings are widely used in construction of engines as crankshaft and connecting rod inserts. These bearings have mostly operative antifriction layer made from aluminum-tin alloy with good performance. The antifriction layer is usually bonded with steel base by rolling. If steel base thickness is not more then 4 mm then rolling-process faces no difficulties. In big Diesel engines of ships and railway locomotives bearings with steel substrate of thickness up to 20 mm in many cases should be used (1). Therefore rolling-technology faces some difficulties in bimetal production and explosive welding can compete with rolling successfully.
