Our titanium welding wire AWS A5.16 adheres to the stringent American standard titanium alloy grade system that fully complies with ASTM, AWS, and ISO welding standards. It covers mainstream welding materials such as ER-Ti-1, ER-Ti-2, ER-Ti-5, and ER-Ti-23, with stock sizes ranging comprehensively from 1.0mm, 1.2mm, 1.6mm, 2.0mm to 3.0mm. We also offer two types-spool wire and straight bar-tailored to customer process requirements. For pressure vessels, aerospace structural components, and chemical equipment welding, we commonly stock high-demand specifications like ER-Ti-2 (1.6mm/2.0mm) and ER-Ti-5 (1.0mm/1.2mm). For precision welding, medical devices, and high-end sports component repairs, we provide ER-Ti-23 wire in the 1.0–2.0mm range, characterized by high strength, excellent plasticity, and stable microstructure, making it suitable for high-performance thin-walled titanium structure welding. All materials undergo testing for gas content, surface brightness, tensile strength, and chemical composition to ensure minimal spatter during welding, stable bead formation, and superior joint mechanical properties.

As a manufacturer, we hold a significant advantage in the stock system for AWS A5.16 titanium welding wire. Firstly, we maintain year-round inventory of several dozen tons for U.S. standard welding wire models corresponding to GR1/GR2/GR5/GR23, ensuring rapid delivery during peak seasons for aviation maintenance, chemical engineering, or OEM production. Secondly, we have specifically optimized the customization scope for foreign trade clients, including minor composition adjustments, tighter wire diameter tolerances (down to ±0.01mm), control of wire coiling, enhanced surface brightness grades, vacuum packaging options, and small-batch trial sample customization, enabling precise matching of welding processes across different countries. We offer secondary cleaning, stricter annealing, and super-bright surface polishing treatments for the welding wire to meet high-purity welding requirements. With years of export experience, we are well-versed in welding parameter preferences across industries and can provide corresponding wire structure recommendations and customized solutions.
Our control over product consistency and stability is fully traceable at the manufacturer level. Complete quality records are available for each melting batch, heat treatment batch, and wire drawing batch, accompanied by material reports, mechanical property data, and gas content test documents. Whether used for welding in high-end precision equipment or for the production of architectural or industrial-grade titanium structures, we ensure that AWS A5.16 series welding wires meet the performance standards expected by the international market in terms of welding fluidity, dimensional accuracy, joint strength, and corrosion resistance.
Why choose us
The core reason for choosing us lies in our "deep customization capability." We not only provide standard ER-Ti-1/2/5/23 filler wires but also enable fine-tuning of wire formulations based on clients' specific welding base materials and project requirements. This includes optimizing aluminum and vanadium content ranges, as well as controlling gas levels such as oxygen and nitrogen to lower thresholds, with strength, ductility, and weld fluidity serving as key regulatory parameters. In specialized industries like medical, aerospace, or deep-sea environments, we further implement processes such as multi-stage annealing, super-bright surface treatment, and online surface defect detection to ensure stable droplet transition and higher weld seam density during welding. Customizable packaging, vacuum oxygen-lock packaging, and small-batch trial production capabilities also allow clients to achieve fully process-matched materials at minimal trial-and-error costs.
The second reason to choose us is our "comprehensive collaborative service and rapid delivery system." With years of export experience, we have established a professional engineering team to conduct working condition analysis, provide welding technology recommendations, and guide wire model and size matching for each client. Leveraging long-term stock inventory, we can swiftly complete cutting, straightening, cleaning, and packaging upon receiving orders.Coordinating customs clearance and documentation with international logistics, we make it possible for customers based in Europe, the Middle East and Southeast Asia to get welding wire that meets their needs in a very short cycle.We offer free material reports, factory inspection records, and SGS or
The third reason to choose us is "long-term after-sales and technical support." We have established a welding issue feedback mechanism for welders and factories across different countries. Any questions regarding weld formation, fluidity, base material compatibility, or shielding gas combinations can be promptly addressed with professional responses from our engineers. If clients encounter issues such as fluidity deviations, material composition adjustments, or processing method modifications during production, we can immediately provide optimized solutions or even redesign customized specifications for long-term clients. We value every mid-to-long-term collaboration, continuously enhancing production stability through ongoing technical guidance, cost-saving proposal recommendations, and periodic quality follow-ups.

1.Does your AWS A5.16 titanium welding wire support deep customization based on project requirements?
Chenxin Titanium: Absolutely. We can not only customize the chemical composition ranges of ER-Ti-1/2/5/23 according to base material grades and industry needs, but also adjust wire diameter precision, straightness, surface brightness levels, annealing state, gas content control ranges, and packaging methods. For example, aviation clients prefer stricter straightness and lower oxygen content, for which we employ double annealing and cleaning processes. Medical clients require higher polishing brightness and more stable consistency, for which we use independent small-batch drawing lines. All customization processes can be accompanied by corresponding quality records and reports.
2: Do you offer any after-sales technical support in case of low welding crust or excessive spatter while in use?
Chenxin Titanium:Of course, we have a group of professional welding engineers to analyze welding current, welding voltage, shielding gas purity, torch angle, base material surface situation, and wire type compatibility, etc., and provide you with the solution. If it is necessary, we can also offer sample replacement, batch adjustment, or secondary annealing and cleaning of wire to help your company obtain consistent processing quality. We consider after sales service as a long term cooperation, not a one time service.
3: Is it possible to make suggestion to which ER-Ti series welding wire to choose if the customer is not sure?
Chenxin Titanium:Certainly. The most appropriate AWS A5. 16 grade will be selected with the consideration of the performance of the base material that is welded by the customer, such as Grade 2, Grade 5, Grade 23 or other titanium alloys and the conditions where it is applied (pressure vessels, thin-walled structural members, chemical pipelines, aviation repairs, medical welding, and etc) and allowed thickness range.For example, thin-walled applications typically use 1.0–1.6mm, while industrial structures may employ 2.0–3.0mm. We will also offer optimization suggestions tailored to the customer's welding machine type and usage habits.
4: Do you allow small-batch customization?
Chenxin Titanium:We fully support it. To help customers reduce costs during new project launches, soldering experiments, or production transitions, we offer small-batch customization starting from dozens of kilograms. This includes adjustments in wire diameter, surface finish, annealing, packaging, and more. Even for highly precise or industry-specific requirements, we can complete them within a short lead time, enabling customers to maintain flexibility during the verification phase of new products or materials. We believe flexible MOQ is key to securing long-term cooperation with multinational clients.
5: Can you provide complete documentation and quality traceability if the client requires it?
Chenxin Titanium:We can provide a full set of documents, including chemical composition testing, mechanical property reports, gas content, dimensional reports, annealing records, batch traceability information, and third-party testing support when needed. We fully understand the documentation requirements of foreign trade clients during bidding, audits, factory inspections, or production verification. Therefore, all AWS A5.16 titanium welding wires come with a transparent and traceable documentation system to ensure clients have verifiable records at every stage.
