E71T - Flux Cored Welding Wire

Our E71T welding consumable is a versatile and reliable flux-cored wire designed for a wide range of welding applications. It is suitable for both single-pass and multi-pass welding processes, making it ideal for various welding projects. The E71T wire offers excellent weld quality, high deposition rates, and easy slag removal, ensuring efficient and productive welding operations.

What is E71T

What is E71T

      E71T is a type of flux-cored welding wire that contains a flux compound within its core. This eliminates the need for an external shielding gas, making it a self-shielding wire. The “E” in E71T stands for electrode, indicating that it is an electrode-type welding consumable. The “71” denotes the tensile strength, which is approximately 71,000 pounds per square inch (psi).

How E71T Works

      During welding, the flux core of the E71T 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 E71T makes it highly convenient for outdoor and windy conditions where using an external shielding gas may be challenging.

Product Structure Analysis

      Our E71T 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.
