Abstract

For the electric resistance welding of a metal tube 9 onto a wall of metal sheet 2, the tube 9 is prepared with a set of tabs 11 protruding radially from its outer surface which are obtained by the plastic deformation of the wall of the tube by means of two punches which move one towards the other in a direction tangential to the axis of the tube 9. <IMAGE>
