The following fitotemerit Is a full description of this Invention, iluding the bast method of performing It known to Note: iThe description Is to be typad In double spacing, plea type face, In- an area not oxc66ding 260 mm In depth and 100 mm in width, on Ituh white paper of good quality and It Is to be Inserted InsIde this form, 14099170-L Ptinttd by 0 I.T~fommo, Commtonwealth Gowmrment Printer. Canberra THIS INVENTION RELATES TO A METHOD OF WELDING TOGETHER STEEL OR OTHER METALLIC OR PLASTIC PIPES, SUCH AS USED IN THE CON- STRUCTION OF OVERLAND OR S1UB-SEA PIPELINES, USING EXPLOSIVE! IMPLOSIVE CHARGES.
THE, 'MrTHOD DIFFERS FROM CONVENTIONAL WELDING TECH1NIQUES IN THAT, INSTEAD OF ELFCTPRIC MWC OR OTHER CONVENTIONAL WELDING NIRT1IODSi, TWO EXPLOSIVE CHARGES ARE USED TO WELl) SUJITAB3LY PREPARED PIPE ENDS TO AN OUTE~R COUPLIENG SLEEVE.
