Corrosion properties - weld metal
Sandvik 24.13.LSi is normally used for joints between non alloyed or low alloyed steels and stainless steels where resistance to corrosion is of secondary importance.

Sandvik can provide recommendations for shielding gases.
Short-arc welding is used with light gauge material of less than about 3 mm, in depositing root runs, and in welding out-of-flat positions.
The higher the inductance in short-arc welding, the higher the fluidity of the molten pool.
Spray-arc welding is normally used for heavier gauge material.
TIG welding
The parameters for TIG welding depend largely upon the base metal thickness and the welding application.
Electrode negative and a shielding gas of argon or helium should be used to prevent oxidation of the weld metal.
Disclaimer: Recommendations are for guidance only, and the suitability of a material for a specific application can be confirmed only when we know the actual service conditions. Continuous development may necessitate changes in technical data without notice. This datasheet is only valid for Sandvik materials.
