The S-7018.1 is an iron powder low-hydrogen electrode engineered for high-efficiency welding of 490 MPa (73,000 psi) class high-tensile steels. It is ideal for applications in bridges, buildings, rolling stock, and low-temperature environments. This electrode provides excellent usability with both AC and DC currents and can be used in all welding positions. It offers a stable arc, smooth bead appearance, and easy slag removal. Additionally, the weld metal ensures good mechanical properties, crack resistance, and reliable X-ray performance.

Features:

High deposition efficiency due to iron powder content
Suitable for all-position welding
Good mechanical properties and crack resistance
Easy slag removal and smooth bead appearance
Applicable for various high-tensile steel structures and low-temperature environments

Usage Instructions:

Dry the electrodes at 350–400°C (662–752°F) for 30–60 minutes before use.
Store the electrodes at 100–150°C (212–302°F) if not used immediately after drying.
Use the back-step method or strike the arc on a small steel plate to prevent blowholes at arc initiation.
Employ wind protection when welding in strong wind conditions.
