DE-LUNA-ALANIS, René-Eduardo  e  GOMEZ-PEREZ, Carlos-René. Influence of the colt metal welding parameters on the AA5083 and AA6061 aluminum. Ingeniería Mecánica [online]. 2015, vol.18, n.1, pp. 42-51. ISSN 1815-5944.

The work objective was to evaluatethe influence of Cold Metal Transfer process arc and pulse corrections and welding speed on the mechanical properties of AA5083 and AA6061 aluminum alloys. For it, a Factorial Multilevel experimental design whit 4 independent factor (arc correction, pulse correction, welding speed and alloy) was developed. The essential welding parameters employed were: base current 250 A; arc voltage 21 V and polarity (DCEP). The evaluation was made whit a transverse traction test of plate welded coupons. The experimental model applied was adequate and substantial differences was showed between yield tensile strength 29,56 %, elasticity module (51,16 %) and specific work of elastic deformation 42,30 %, which it does not possess a lineal dependence whit the rest of previous properties.
