Techalloy offers a wide variety of nickel grades, product forms
and packages for all applications that require high quality nickel
welding wire. Nickel alloys often are used in severe service conditions
where extreme heat, corrosion, abrasion, high pressures and combinations
of these conditions are present. Techalloy 625 is the most popular
grade, with many applications in fabrication and overlay in the petrochemical
and power generation industries.
Product forms include continuous wires on spools used in the Gas
Metal Arc Welding process (GMAW or MIG). Techalloy brand nickel solid
MIG wires offer superior weld and feedability performance due to
their unique manufacturing process.
Techalloy solid nickel wires for Tungsten Inert Gas welding (TIG)
exhibit an extremely clean surface free of contaminates and are ink
jet imprinted with the grade and heat for guaranteed traceability
and improved productivity.
Techalloy brand coated electrodes are sold under the trade name
Tech-Rod. Coated electrodes are used in the Shielded Metal Arc Welding
(SMAW) process. The flux coating contains various minerals to impart
specific welding characteristics. All Tech-Rod Nickel electrodes
with a balanced chemistry.
Techalloy solid nickel wires for Submerged Arc Welding (SAW) are
annealed at size to produce a safer, easier handling product with
more consistent joint tracking.
Most nickel base solid wires are produced to AWS A5.14 requirements.
The copper/nickel grade Techalloy 413 is produced to AWS A5.7. Techalloy
99 for cast iron welding is produced to AWS A5.15.
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 chemistry certifications are available free of charge.
