Features
ERTi-12 welding wire possesses moderate strength and excellent resistance to crevice corrosion. It exhibits excellent weldability, stable mechanical properties of the deposited metal, a tensile strength of up to 480 MPa, a yield strength of 340 MPa, and an elongation of 15%.
Standards
This welding wire conforms to several international standards, including:
• AWS A5.16 ERTi-12
• GB/T 30562 STi 3401
• NB/T 47018.7 ER TA10
• EN ISO 24034:STi-3401
Main Applications
ERTi-12 welding wire is primarily used in the chemical and pressure vessel industries, particularly suitable for welding various chemical reaction vessels, pressure vessels, and piping systems. Its excellent corrosion resistance makes it an ideal alternative to expensive ERTi-7 welding wire.
Welding Process Requirements
High-purity argon gas with a purity of ≥99.99% is required as a shielding gas during welding. A low heat input and few-layer welding process is recommended. Before welding, thoroughly remove oil, rust, moisture, and other impurities from the welding surface. During welding, avoid swaying or use only small-range swaying to ensure effective shielding.
Product Specifications
ERTi-12 welding wire is available in various specifications, with diameters ranging from 0.8mm to 4.0mm. It is packaged in coils and straight wires, with a typical length of 1000mm, meeting the needs of different welding processes.
