32-34 CERCETĂRI ŞI EXPERIMENTĂRI PRIVIND OPTIMIZAREA REGIMULUI DE SUDARE CU ARC ELECTRIC PENTRU COMPONENTE DIN TABLĂ CU METODA GRADIENTULUI

RESEARCH AND EXPERIMENTATION ON OPTMIZING REGIME FOR WELDING COMPONENTS WITH

GRADIENT METHOD

 

The paper presents the calculation algorithm and the optimal solution calculated gradient method, an experimental program conducted on board the components of arc welding in the environment of protective gases. Welding regime parameters on variation conclusions have been drawn, then the gradient method was chosen optimum welding regime.

30-15 CERCETĂRI PRIVIND REABILITAREA PIESELOR PRIN ÎNCĂRCARE CU SUDURĂ

RESEARCH ON THE REHABILITATION OF PARTS
HARD SURFACING
The article presents a commonly used method for rehabilitation of parts
by welding load. The quality of rehabilitation is assessed by a set of
characteristics that give the reconditioned piece, the ability to meet the
necessary requirements, operating under normal conditions. Welding
instructions through material loading, are applied to the achievement of Francis
rotors type, on two components 1.4317 (GX4CrNi13-4)/SR EN 10213-2 cast
steel. These steels are ideal in terms of use conditions, where wear resistance
is really important, such as on hydraulic turbine components.
Keywords: rehabilitation, arc welded parts, charging by welding
