AWS Class ERZr2 MIG & TIG welding wires are composed primarily of zirconium (Zr ≥ 99.2%), with trace elements such as Hf (≤ 4.5%), Fe (≤ 0.2%), and other impurities kept below 0.1%. This composition provides excellent corrosion resistance, particularly in strong acids and seawater environments. Mechanically, ERZr2 offers a tensile strength of approximately 330–480 MPa, yield strength around 230 MPa, and elongation of 20–30%. Its outstanding ductility, toughness, and resistance to high-temperature oxidation make it ideal for critical industrial and chemical applications.

At Hajji Welding Supplies, we take pride in being one of Tunis’s trusted suppliers of high-quality welding consumables. Our expertise lies in AWS Class ERZr2 MIG & TIG, engineered for precision, durability, and resistance to corrosion. With a strong commitment to quality and customer satisfaction, we provide welding solutions that support industries across construction, energy, shipbuilding, and manufacturing.
AWS Class ERZr2 MIG & TIG welding wires are widely used for joining zirconium and zirconium alloy components where exceptional corrosion resistance and strength are required. Common applications include chemical processing equipment, heat exchangers, pressure vessels, and piping systems exposed to strong acids such as hydrochloric, sulfuric, and nitric acids. They are also utilized in nuclear power plants, marine environments, and aerospace industries due to zirconium’s low neutron absorption and high-temperature stability. ERZr2 ensures high-quality welds with excellent ductility and performance, making it ideal for demanding industrial and engineering applications.
The Hajji Industries Server is built to deliver reliability, speed, and scalability for mission-critical operations. Designed for modern industrial environments, it ensures seamless performance in manufacturing, engineering, energy, and automation sectors.
