It is difficult to join a stainless steel handle to an aluminium alloy bowl of a cooking pan in a permanent and secure way. Therefore, a hexagonal stud is adhered to the outside of the bowl and a stainless steel patch is fixed to that stud by providing a hexagonal hole through which the stud passes to prevent twisting of the patch relative the stud and the outer end of the stud is riveted over to hold the patch in permanent face to face contact with the outside of the bowl. Thereafter, the handle is spot welded to the patch.
