Frequently Asked Questions

Q: How should I dry AWS E308/308L electrodes before use?

Electrodes should be dried at 250-300°C for 60 minutes. During welding, keep the consumables for half-day use in an environment maintained at 100-150°C.

Q: Which base metals are compatible with E308/308L?

These electrodes are ideal for AISI-304, AISI-301, and AISI-302 stainless steels, including pipes, thin plates, and pressure vessels.

Q: What is the recommended weave method for these welding rods?

When using the weave method, the moving range should be strictly controlled within 2.5 times the diameter of the welding wire.

Q: Why is lower current recommended during the welding process?

Using a lower current helps prevent cracking and minimizes base metal dilution, preserving the chemical integrity of the weld.

Q: How do I prepare the base metal groove for welding?

Ensure all contaminations are cleaned from the base metal groove. Use a dedicated stainless steel brush to ensure a pure welding surface.

Q: What are the mechanical properties of the deposited metal?

The deposited metal features a tensile strength of 570 Mpa and an elongation rate of 45%, ensuring high durability and flexibility.
