During ''hot cladding'', the classic process, the materials to be clad are assembled into a cladding package in block or plate form, heated to about
800°C and clad (or “welded”"welded") together under high pressure <xr id="fig:Hot_cladding_of_pre-materialsHot_cladding_of_pre_materials"/> (Fig. 3.3). At the interface between the two materials a non-separable bond is formed by either diffusion of the reaction partners or in liquid phase by forming a AgCu eutectic alloy when an additional brazing alloy foil is placed between the two materials. Further processing is done by rolling with required annealing steps between subsequent thickness reductions. The disadvantage of this process is the usually limited short length of final material strips.
