Product Detail
Product Introduction
ERTi-2 Titanium Welding Wire is a clean titanium filler metal for GTAW, GMAW or other qualified welding processes as applicable. Filler classification must be selected with the base metal, corrosion environment, joint design, shielding practice, welding procedure and required weld-metal acceptance.
When is ERTi-2 welding wire selected?
Selection answer: ERTi-2 is a commercially pure titanium filler classification commonly considered with Grade 2-family fabrication for chemical equipment, heat exchangers and general corrosion-resistant weldments.
Selection boundary: Filler selection is not established by matching the grade number alone. The qualified WPS must account for both base materials, dilution, joint design, service corrosion, shielding coverage and required weld-metal properties.
RFQ data to confirm: State AWS or ISO classification, base-metal grades and specifications, process, wire or rod diameter, spool or straight length, package weight, joint and service details, WPS requirements, quantity and certificates.

Wire is protected in coils, spools or straight-length bundles with moisture-resistant wrapping and labels for grade, diameter, heat and quantity. Typical export packaging for the same physical product form is shown below; final packing is confirmed for each order.
Application Scenarios
General commercially pure titanium welding with corrosion resistance and useful ductility
Material grade, dimensions, condition and inspection must be matched to the application requirements.
Chemical and marine fabrication

Aerospace and industrial welding under qualified procedures
Material grade, dimensions, condition and inspection must be matched to the application requirements.
FAQ
Can titanium welding wire be selected only from the base-metal grade?
No. Filler selection must follow the qualified welding procedure, applicable code, joint design, corrosion requirements and project acceptance criteria.
Why are surface cleanliness and packaging important?
Titanium welding is sensitive to contamination. Clean surface, protected packaging and controlled handling help prevent weld defects and loss of corrosion performance.
What information is required for quotation?
Provide AWS/ISO classification, diameter, spool/coil/rod form, package weight or rod length, quantity, process, base metal, tests and certificates.
