#CMT# #/CMT# Induction heating apparatus for joining parts together comprises a heat shield and a cooling system comprising a primary circuit for cooling the apparatus and a secondary circuit for cooling the heat shield. #CMT#USE : #/CMT# The apparatus is useful for joining two automobile bodywork parts together (claimed), especially a body side and roof, e.g. by brazing or by spot polymerization of a glued joint. #CMT#METALLURGY : #/CMT# Preferred Apparatus: The heat shield is made of copper and has a contact surface complementary to the contact surface of the parts being welded. The heat shield is dimensioned so that there is a fixed distance between the field concentrator of the apparatus and the parts being welded.
