CHE SIGNIFICA SUBMERGED ARC WELDING IN INGLESE
Saldatura ad arco sommerso
La saldatura ad arco sommergibile è un processo di saldatura ad arco comune. Il primo brevetto sul processo di saldatura ad arco sommerso è stato estratto nel 1935 e coperto un arco elettrico sotto un letto di flusso granulato. Originariamente sviluppato dalla Linde - Union Carbide Company. Richiede un elettrodo solido o tubolare consumabile non continuamente. La saldatura fusa e la zona arco sono protetti dalla contaminazione atmosferica essendo "sommersi" sotto una coperta di flusso fusibile granulare costituito da calce, silice, ossido di manganese, fluoruro di calcio e altri composti. Quando fusi, il flusso diventa conduttivo e fornisce un percorso di corrente tra l'elettrodo e l'opera. Questo spessore strato di flusso copre completamente il metallo fuso, evitando così spatter e scintille e sopprimendo l'intenso radiazione ultravioletta e fumi che fanno parte del processo di saldatura ad arco metallico schermato. La SAW è normalmente operata in modalità automatica o meccanizzata, tuttavia sono disponibili pistole semiautomatiche SAW con alimentazione a flusso pressurizzato o di gravità. Il processo è normalmente limitato alle posizioni di saldatura piatte o orizzontali.
definizione di submerged arc welding nel dizionario inglese
La definizione di saldatura ad arco sommerso nel dizionario è un tipo di saldatura ad arco elettrico pesante con filo nudo alimentato meccanicamente con l'arco immerso nel flusso di polvere per tenere fuori l'ossigeno.

Submerged-arc welding (SAW) is another type of arc-welding process. The word
submerged means to be completely covered. When we weld using the SAW
process, a blanket of flux shields and submerges the arc and the molten weld
pool.
