Abstract

 To determine the mechanical properties of a welded joint becomes necessary to know the mechanical properties of filler metals arising from a welding process. The objective of this work is to check the mechanical properties of a weld MAG developing and qualifying a welding procedure. For this we will use four mechanical tests: traction, determines the yield, of rupture, elongation and contraction; macrographic, determine, to the naked eye, the molten zone, the zone, the zone thermally affected zone and the base metal; micrographic, determines the micro-structural components of weld and base metal; hardness, the tenacity of the weld and base metal.
