Abstract
In this study, AISI 420 martensitic stainless steels were welded by GTAW (gas tungsten
arc welding) using ER 316L consumables. Pure argon, argon + 25% He and argon + 5% N2 were
used as shielding gases. The obtained results indicated that shielding gases have some effect on the
properties of the martensitic stainless steel weldments. The use of argon+5%N2 provides the highest
tensile strength values and higher microhardness profile compared to the other shielding gas
composition used.
