Frequently Asked Questions

Q: How should AWS E308-16 electrodes be dried before use?

Titanium-calcium types should be dried at 150°C for 1 hour, while low-hydrogen types require 200°C to 250°C for 1 hour. Avoid repeated drying to prevent coating peel-off.

Q: What is the recommended welding current for stainless steel electrodes?

To prevent intergranular corrosion, the welding current should be approximately 20% lower than that used for carbon steel electrodes.

Q: Which positions can be welded with different diameters of E308-16?

Diameters of 3.0mm and below are suitable for all-position welding, while diameters above 3.0mm are recommended for flat and fillet welding.

Q: Why use DC power supply instead of AC for lime-titania coatings?

While AC is possible, it often results in shallow penetration and a higher risk of redness; DC power supply provides deeper penetration and a cleaner weld.

Q: What are the primary applications for the E308-16 electrode?

It is primarily used for welding corrosion-resistant 0Cr19Ni9 and 0Cr19Ni11Ti stainless steel structures in chemical plants and petroleum equipment.

Q: How can I avoid carbon contamination in the weld?

Ensure the electrode coating is kept dry and free from oil or dirt, as contaminants can increase carbon content and compromise weld quality.
