Abstract

Metal workpieces (I) are welded using a filler or brazing material with m.pt. lower than (I) esp. the welding of large thin pieces where part of the joint is not flat. Welding is carried out using two pressure plates, >=1 contg. an induction heating coil, and an insulating plate. The improvement is that a metal element with suitable magnetic properties, and a different coefft. of expansion to (I), is placed round the parts of the joint which are not flat so the latter are heated by conduction from the element; the element is heated by induction and press. is exerted on the joint in a radial direction during welding. The metal element is pref. a ring with a lower coefft of expansion than (I) so that radial pressure is exerted on the joint while axial pressure is applied by a press. Induction and conduction heating are combined with pressure to make good joints.
