Shielded metal arc welding of dissimilar metals such as stainless steel to carbon steel or low
Under layer welding of the cladded side groove of SUS304L clad steel, or of 308L weld
overlaying onto carbon steel or low alloy steel.
Characteristics on usage
NC-39L and HIMELT-309L are lime-titania type electrodes, and HIMELT-309L makes higher
efficiency by higher amperage.
As the weld metals contain larger quantity of ferrite in austenitic structure, the weld ability is
They provide good corrosion resistibility and good heat resistibility in as-welded condition.
They are suitable where the dilution by base metal carbon steel or low alloy steel is
