E81T-B2C - Flux Cored Welding Wire
Suitable for welding of 1.0%Cr-0.5%Mo high temp.steel for power plant,boilers,pressure vessel,chemical industry,etc.
What is E81T
It is a titania type flux cored wire for all-position welding and be used for welding of 1.0%Cr-0.5%Mo high temperature steel.Arc is stable,low spatter generation,beautiful bead appearance and good slag removal.
How E81T Works
During welding, the flux core of the E81T 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 E81T makes it highly convenient for outdoor and windy conditions where using an external shielding gas may be challenging.
Our E81T 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.
