Evaluation of the cross-section of the weld MAG methods
Pop, Vojtěch ; Daněk, Ladislav (referee) ; Kubíček, Jaroslav (advisor)
This thesis focuses on the design of welding parameters and subsequently evaluates profile of the weld that is welded by the MAG method. On the basis of the literature study on arc welding v protective atmospheres, a 1 mm diameter welding was designed according to OK AristoRod 12.50 catalogue and chemical composition corresponding to G3Sil. A 4 mm thick steel sheet made from ČSN 11 375 steel was welded and the welding was conducted in protective atmosphere M21, which equals a mixture of Ar + 8% CO2. Welding was conducted using two types of an arch, impulse and short-circuit, and the source was Aristo Mig U5000i. Final mechanical properties and chemical composition of the weld is included in the attachment, where we can find the inspection certificate 3.1.
