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.

Description

technical field [0001] The present disclosure relates to welding techniques, and more particularly, to methods and systems for welding two or more pipes. Background technique [0002] Piping pieces such as tubes or tubes are welded together circumferentially to construct desired lengths of piping for use in a variety of applications including, but not limited to, in heat exchangers or as generally used in various industries Transportation pipelines for the transportation of chemicals, mineral oil and natural gas, etc. Welding pipe pieces to each other requires a lot of care, time and skill, making it rather expensive. When welding pipe fittings, there is a high chance of welding material depositing in and around the weld zone. Deposition of weld material along the inner surface of the pipe can reduce the life of the pipe being welded due to corrosion that can be caused by particulates traveling through the pipe being welded. Many attempts have been and are still being mad...
