Submerged Arc Welding Wire

Overview

Submerged Arc Welding Wire

● Superior feedability and excellent arc characteristics

● Made up of carbon steel and low -alloy steel

● Characterized with the execllent welding performance.

● Stable feeding, and beautiful welding seam

● Relatively moderate welding smoke and splash,

● With liquidity and crack resistance rather superior.

● The welding slag will be thin and easy to be peeled off

● The welding seam holds high tensile strength and excellent low-temperature impact resistance performance.

● Applied for all-position welding and a larger current range.

Notice:

1. The wires must be stocked in dry circumstances. Don't open the dampproof package of spools to avoid rust.

2. Before welding, rust, oil, water and impurities are to be cleared from the welded surfaces of workplaces.
