VERFAHREN ZUM SCHWEISSEN VON AUS HOHEM AUSTINITISCHEN CHROM BESTEHENDEM ROSTFREIEN STAHLROHR UND SCHUTZGASGEMISCH ZUM SCHWEISSEN |
| 摘要 |
Stainless steels are welded using a shielding gas including 88 to 98.9 mole% Ar, 1 to 10 mole% H2, and 0.1 to 2.0 mole% CO2. The shielding gas permits low sulfur, high chromium, austenitic stainless steel pipes to be joined with welds having sufficient penetration, strength, corrosion resistance and durability for practical use. <IMAGE> |
