Quality and Productivity Increment in Welded Joints with GMAW-M Process for Parcial Fusion Depth 942423
This paper presents the research and development of a problem solution that consist in the fault of fusion depth in the inferior fixation of Mc Pherson's shock absorbers, which could occur an assembly break when in use, resulting in great possibilities to happen serious accidents.
This started by the necessity to promove the welding process stability and to warrant totally the quality of these welded joints.
Primely we made an empirical development, where we change the size of the utilized wire to a great one, that proportionated an increase in the electric arc characteristics, resulting in the desired quality and a productivity gain, using only the open arc time.
We used in this work automatic equipments, provided with welding digital pulsated sources and hydraulic movement to welded assemblage.
So, we obtained a good result in one type, mainly, and afterwards we made a mathematical modeling based in the Heat Input and Mass Input of the joint, making possible to calculate the welding parameters to other products.
