DETAILS
THY-70MC (E70T-1C) is a 500 MPa class metal-powder type gas-shielded flux-cored wire featuring high deposition efficiency. It is specifically designed for flat and horizontal fillet welding in automatic and semi-automatic operations.
Features
- Metal-powder type flux-cored formulation delivering exceptionally high deposition efficiency
- Engineered for high-speed flat position and horizontal fillet welding
- Stable arc performance with minimal spatter and smooth, deep-penetrating weld beads
- Excellent usability in both automatic and semi-automatic welding setups
Typical Applications
- Heavy structural steel fabrication, industrial buildings, and bridge construction
- Shipbuilding, barge manufacturing, and offshore structural components
- Heavy machinery manufacturing, crane frames, and earthmoving equipment
- Storage tanks, pressure vessels, and large-diameter carbon steel piping
- General high-efficiency flat and horizontal fillet joint welding on carbon steels
Welding Positions
- PA / PB
WARNING
- Use DC⁺ only.
- Use CO₂ shielding gas (purity ≥ 99.9%) at a flow rate of 20–25 L/min.
- Maintain an interpass temperature of 150–200°C (300–390°F) during multi-pass welding.
