"Welding process migimag pulsed thermal pulse or double pulse".The present invention, in only one case, combines the characteristics of a pulse of current processes MIG / MAG and TIG, thus providing a transfer metal controlled.Minimizing the salpicagem, a deposit of material with better wettability, improving the finish and minimizing the lack of fusion.A better control of the penetration of the root pass and a better sustentacu00e3o puddle welding out of metal in flat position.These characteristics, which improve the result of recovery by welding of hydraulic turbines cavitation eroded, and also improve the controllability of the root pass of welded joints.When you can 't use kill together or welding by the reverse side.The said process consists of the introduction of a pulse of electrical current at low frequ00b3u00eancias (7), which is a characteristic of pulsed TIG process.In a pulse of electrical current in high frequ00b3u00eancias (2), which is a characteristic of the pulsed MIG / MAG process, resulting in a doubly pulsed this superposition current (4).
