The pipelines used for carrying fluids and gas, made of specially designed steels in keeping with their intended uses, are obtained by welding on generator or spiral welding, a wide range diameters (from 350 to 1800 mm) pipe wall widths (between 6 40 mm). At present, the following procedures used: automatic submerged arc (with 1 2 wires), combined unilateral bilateral MIG/MAG procedure, according plate thickness edge working method. Ongoing researches focus improving end product [1, 2, 3, 4, 5, 6] replacing procedure other which use less energy have high deposit rates. This paper presents results using tandem MAG two wires (2 x ø1.2 mm), Y joint X52MS steel plates. welds were carried out QUIROX 315 robot, 2-wire head, supplied QUINTO-GLC 603 sources, equipment found at Research Centre C12, Advanced Welding Eco-Technologies, owned ICDD - UTBV. tests (carried as per enforceable regulations) concerning characterisation executed proved that it is possible obtain lower material-relates costs productivity quality.
