An embodiment of a method for interconnecting tubular sections includes the steps of vertically positioning a second tubular above a first tubular forming a seam defined by a bottom end of the second tubular and a top end of the first tubular; positioning a friction stir welder (FSW) proximate to the seam; aligning the first tubular and the second tubular to form a longitudinal axis; and guiding the FSW along the seam forming a weld joint. The FSW guidance system comprises a laser temography apparatus. The method further includes a step of inspecting the weld joint by inspecting apparatus which comprises an ultrasonic testing system.
Selon l'invention, un mode de réalisation d'un procédé de raccordement de parties tubulaire consiste : à placer verticalement un deuxième élément tubulaire au-dessus d'un premier élément tubulaire, de sorte à former une ligne de soudure définie par l'extrémité inférieure du deuxième élément tubulaire et l'extrémité supérieure du premier élément tubulaire; à placer une soudeuse par friction-malaxage (FSW) à proximité de cette ligne de soudure; à aligner le premier et le deuxième élément tubulaire pour former un axe longitudinal; et à guider la soudeuse le long de la ligne de soudure, de sorte à former un joint de soudure.
