Abstract

A system 100 and a method 600 for welding two or more conduits 200, 300 are disclosed. The system 100 includes a root welding tool 110, a filler welding tool 120 and a support member 130. The root welding tool 110 root weld a gap 400 to form a root layer 410 configured along end portions 210, 310, from outer circumferential surfaces side 220, 320 opposite to inner circumferential surfaces side 230, 330 of conduits 200, 300. The root weld is performed such that spattering of root weld material is prevented. The filler welding tool 120 is utilized to fill the gap 400. The support member 130 is provided for applying an outward thrust to ensure shrinkage of the filler and root weld materials longitudinally and radially outward, preventing pressing out of the filler and root weld materials along the inner circumferential surfaces side 230, 330.
