Abstract
The invention relates to a method of welding together metal elements by means of explosion-welding. To limit the quantity of charge required, the charge is enclosed in an inert cylindrical medium serving as blasting medium and medium for transmitting shock waves. This shape eliminates the dependence on detonation speed and high-precision explosive charges can be selected, which can be detonated at small cross-sections. The cylindrical shape of the splicing material increases the tolerance limits for irregularity of the metal elements. A further embodiment of the invention also permits splicing from both sides of the elements, thus eliminating the need for supports to impede deformation.
