Method and machine to be welded of the metal pieces under pressure and the pieces thus obtained

摘要

P the machine according to the invention is distinguished by a certain number of fixed elements in the form of a c 10 and of the slides 16 in the form of a c between the fixed elements, the fixed elements supporting the door - matrices 22 fixed and mobile dies door - 24 and the sliders carrying the door - matrices 26 fixed with respect to the sliders and of the door - matrices 28 movable relative to the sliders and of the jacks 32, 40 and 50 in order to clamp the two parts to be welded between the dies and after their closeness to the alignment, their separation, for the heating by a pipe 54 and then moving them for the welding by forging under pressure. / p & & p & this machine is particularly suitable for welding of the plates made of aluminum alloy, and magnesium. / p
