THE INFLUENCE OF THE GAS NOOZLE GEOMETRICAL SHAPE ON THE QUALITY OF THE MAG WELDING DEPOSIT

Abstract

The paper aims to identify the effects on the geometrical configuration of the welding deposit caused by changes in the classical gas nozzle shape. The results obtained in the case of two geometrical shapes of the nozzles are presented after using continuous and pulsed current with short arc and spray arc transfer. The effects on the geometrical elements: deposition width (B) and reinforcement (h), are indicated in tabular and graphical shape.
