METHOD OF TREATING CONNECTIONS OBTAINED BY EXPLOSIVE WELDING

摘要

A method is described reducing remaining tensions and corrosion resistance in welded joints by explosion finishing thereof, comprising disposing over the axis of the weld seam an explosive charge in the form of a periodic curve, the axis of which is substantially co-extensive with that of the weld seam with the amplitude thereof extending from one side of said seam to the other, and then detonating said explosive charge. In one embodiment an auxiliary explosure charge is disposed substantially linearly over the axis of the weld seam to assure complete detonation of the charge disposed in the form of a periodic curve and comprising the main charge, and then both charges are simultaneously detonated.
