DETTAGLI
Progettato per tassi di deposito molto elevati e una maggiore resistenza alle cricche da idrogeno e alla porosità su acciaio contenente zolfo o contaminanti. Raccomandato per la saldatura in passata singola o multipass su acciaio al carbonio e alcuni acciai basso legati in applicazioni senza requisiti di resilienza.
Caratteristiche
- Tassi di deposito molto elevati
- Maggiore resistenza alle cricche da idrogeno e alla porosità
- Arco morbido a bassa penetrazione per una miscelazione minima del materiale base
