THY-70MC (E70T-1C)

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.
