DETALII
Sârmele tubulare din oțel inoxidabil ULTRACORE® asigură proprietăți mecanice uniforme, performanță superioară a arcului, desprindere ușoară a zgurii.
Caracteristici
- Înfășurarea de precizie permite derularea mai stabilă a rolelor și un avans uniform al sârmei
- Acțiunea uniformă a arcului și stropirea minimă reduc necesitatea de curățare după sudare
- Aspectul lustruit al cordonului de sudură reduce necesitatea de periere după sudare
Aplicații tipice
- Îmbinări eterogene – oțeluri inoxidabile tip 410, 304L, 321 și 316L cu oțeluri nealiate și slab aliate
- Straturi tampon și de încărcare – acoperiri pe oțeluri CMn, slab aliate sau nealiate
- Vase sub presiune
Poziții de sudare
- Plat/Orizontal
Gaz protector
- 75% Ar/25% CO2
