Techalloy produces many grades of nickel, nickel alloy and copper/nickel coated electrodes for Shielded Metal Arc Welding. Nickel alloys often are used in severe service conditions where extreme heat, corrosion, abrasion, high pressures and combinations of these conditions are present. Tech-Rod 182 is the most popular grade finding many applications in fabrication in the chemical and petrochemical industries. Techalloy brand coated electrodes are sold under the trade name Tech-Rod. The flux coating contains various minerals and alloy powders to impart specific welding characteristics and deposit chemistries. Most Nickel base electrodes are produced to the requirements of AWS A5.11. Tech-Rod 55 and Tech-Rod 99 used for welding cast iron are produced to AWS A5.15. The copper /nickel Tech-Rod 187 is produced to AWS A5.6. Several grades are also certified to the requirements of the Canadian Welding Bureau, the Military Qualified Products List, the Brazilian Welding Foundation, and TUV. Actual deposit chemistry certifications are available free of charge.
