Abstract

Oppfinnelsen vedrører en fremgangsmåte for sairjnen- sveising av minst to rør som er anordent koaksialt med hverandre akse, hvor en ledering anbringes rundt minst ett av de to rør, og hvor en bærer av minst en sveiselampe ført av lederingen beveges i periferisk retning av rørene, mens minst en sveisestreng påfø- res. Denne oppfinnelse har til hensikt å underlette sveiseoperasjonene og/eller å øke kvaliteten på sveisen. For dette formål beveges sveiselampen i forhold til lederingen ved hjelp av minst en regulert rotasj onsmotor. Oppfinnelsen tilveiebringer også en anordning som er spesielt beregnet på utførelse av fremgangsmåten i henhold til oppfinnelsen. Foreliggende oppfinnelse kan anvendes ved sveising av kjeler og kar hvor en ringsveis anvendes mellom to elementer utformet som rør med sylindriske kanter. ; Oppfinnelsen kan imidlertid anvendes spesielt fordel- aktig i en fremgangsmåte og anordning for legging av e"n rørledning.BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a method of welding wires of at least two pipes arranged coaxially with each other, wherein a conductor is disposed around at least one of the two pipes and wherein a carrier of at least one welding lamp guided by the conductor is moved in a circumferential direction by the pipes. while at least one welding string is applied. This invention is intended to facilitate welding operations and / or to improve the quality of the welding. For this purpose, the welding lamp is moved relative to the conductor by means of at least one regulated rotary motor. The invention also provides a device which is specifically intended for carrying out the method according to the invention. The present invention can be used in welding boilers and vessels where a ring weld is used between two elements formed as tubes with cylindrical edges. ; However, the invention can be used particularly advantageously in a method and apparatus for laying one pipeline.
