E81T1-W2C - Flux Cored Welding Wire

Used for welding 550MPa atmospheric corrosion resistant steel structures,such as railway locomotive vehicles,offshore engineering,bridges,etc.

What is E81T1-W2C

What is E81T1-W2C

    is a titania type flux cored wire for all-position welding and be used for welding of high strength weather-proof steel.Arc is stable,low spatter generation, beautiful bead appearance and good slag removal.The weld-metal contains Cr,Ni,Cu and makes excellent weather-proof properties and crack resistance.

How E81T1-W2C Works

      During welding, the flux core of the E81T1-W2C wire generates a protective gas shield when it reacts with the heat of the arc. This shield protects the weld pool from atmospheric contamination, ensuring a clean and stable weld bead. The self-shielding nature of E81T1-W2C makes it highly convenient for outdoor and windy conditions where using an external shielding gas may be challenging.

Product Structure Analysis

      Our E81T1-W2C welding consumable is composed of several key components that work together to ensure optimal welding performance. The product structure includes:

  • Steel Core: The steel core provides the strength and structural integrity to the welding wire, enabling smooth feeding through the welding torch.
  • Flux Compound: The flux compound is situated within the core of the wire and is responsible for generating the shielding gas during welding.
  • Outer Sheath: The outer sheath acts as a protective layer for the core, ensuring the integrity of the welding wire during storage and handling.
