Direct from Baoji—China's Titanium Valley—to the Port of Turku. Every batch is manufactured under ISO 9001 certified controls, backed by EN 10204 3.1 Inspection Certificates, and strictly compliant with ASTM, ASME, and AWS maritime fabrication codes.
The Finnish city of Turku—celebrated as the capital of Baltic shipbuilding and the cradle of Europe’s luxury cruise ship production at Meyer Turku shipyard—demands an uncompromising tier of structural integrity and metallurgical purity. When welding pure titanium (CP Grades 1, 2, 3, 4) and structural titanium alloys (Grade 5 Ti-6Al-4V, Grade 7 Ti-0.15Pd, Grade 9 Ti-3Al-2.5V, and Grade 12 Ti-0.3Mo-0.8Ni), the filler rod is not merely a consumable; it is the critical determinator of mechanical ductility, crack arrest properties, and electrochemical passivity across the Heat-Affected Zone (HAZ).
As a seasoned titanium manufacturer and global exporter situated in Baoji, Shaanxi—China’s Titanium Valley responsible for over 60% of domestic titanium output—Jovzi Titanium Industry Co., Ltd. bridges global metallurgical manufacturing with the demanding engineering standards of Southwest Finland (Varsinais-Suomi). Titanium is an allotropic element that transitions from a close-packed hexagonal (alpha) phase to a body-centered cubic (beta) crystal lattice at approximately 882°C. During Gas Tungsten Arc Welding (GTAW / TIG) or Plasma Arc Welding (PAW), liquid titanium exhibits an extreme chemical affinity for interstitial contaminants: atmospheric oxygen, nitrogen, carbon, and hydrogen.
Our titanium welding filler wires and cut straight rods conform flawlessly to AWS A5.16 / ASME SFA-5.16 (ERTi-1, ERTi-2, ERTi-5, ERTi-7, ERTi-9, ERTi-12) and EN ISO 24034 standards. By controlling wire surface topography through diamond die drawing and comprehensive chemical pickling, our rods eliminate micro-fissuring and wire feed chatter during automated orbital welding in marine prefabrication shops across Pansio, Raisio, and Naantali.
Turku functions as an epicenter of advanced European naval architecture, marine cleantech, chemical processing, and biotechnology. Titanium welding consumables exported to this region are systematically specified into four cornerstone application domains:
Turku’s maritime suppliers construct heavy-duty sulfur oxide (SOx) wet scrubbers and NOx selective catalytic reduction (SCR) headers. Welding these systems requires AWS ERTi-7 (Grade 7 Ti-Pd) and ERTi-2 rods to combat hot, low-pH sulfuric and hydrochloric acid condensates that corrode conventional super duplex stainless steels.
Naval HVAC cooling loops, plate-and-frame evaporators, and onboard reverse osmosis units fabricated along the Aura River utilize thin-walled titanium tubes welded with ERTi-1 and ERTi-2 rods, maintaining immunity against high-velocity Baltic seawater micro-fouling and crevice corrosion.
Southwest Finland’s forest and bio-chemical processing facilities require titanium piping systems resistant to chlorine dioxide, wet chlorine gas, and sodium chlorate. Our AWS ERTi-12 (Ti-Mo-Ni) welding wire delivers superior resistance against chloride pitting at elevated temperatures.
Pioneering LNG-powered cruise vessels and bio-methane bunkering craft built in Turku depend on titanium weldments for lightweight cryogenic piping. Titanium’s yield and tensile properties improve as temperatures drop toward -196°C without undergoing a ductile-to-brittle transition.
Underwater acoustics, submarine sonar domes, and Baltic seabed robotics demand non-magnetic hull penetrations and high strength-to-weight ratios. Jovzi supplies high-purity ERTi-5 (Ti-6Al-4V) and ERTi-9 (Ti-3Al-2.5V) wire for rigorous automated TIG welding.
In accordance with Finland’s Carbon Neutral 2035 target, hydrogen pilot projects in Turku’s energy cluster deploy titanium bipolar plates and fluid distribution manifolds welded with Jovzi ultra-pure ERTi-1 rods to withstand harsh proton exchange membrane (PEM) operating environments.
Procurement teams and welding coordinators (in accordance with SFS-EN ISO 14731) must balance yield strength, weld pool fluidity, and galvanic compatibility. Below is the technical matrix of Jovzi Titanium’s certified welding wire portfolio available for immediate consolidated delivery to Turku:

Welding titanium in Nordic shipyards requires rigorous environmental management. Turku's sub-arctic coastal climate introduces distinct relative humidity variations between summer and winter, highlighting the necessity of dew-point monitoring in shielding gas streams.
Titanium absorbs hydrogen at temperatures above 250°C, while oxidation and nitridation accelerate exponentially above 425°C. Therefore, when executing GTAW joints on titanium pipe spools or pressure vessel shells, standard shielding gas configurations are insufficient:
1. Primary Torch Shielding: Ultra-high purity Argon (≥ 99.999% purity) with a moisture dew-point of -60°C or lower. A large gas lens ceramic nozzle (No. 10 to No. 16) is essential to provide undisturbed laminar argon flow without turbulent air induction.
2. Secondary Trailing Shield: An auxiliary trailing shoe attached behind the welding torch continuously bathes the cooling solid bead in argon until its metal temperature drops below 400°C. For high-deposition robotic processes, extended water-cooled trailing shields are required.
3. Backing Purge Protection: The root side of pipe butt welds must be purged with oxygen content strictly regulated below 50 parts per million (ppm). Purge dams combined with electro-chemical optical oxygen sensors must verify root chamber inertness before arc strike.
The supply dynamics within the Baltic maritime triangle (Turku – Helsinki – Stockholm – Rauma) have changed dramatically due to shifting geopolitical landscapes and elevated sustainability benchmarks under the EU Green Deal. Buyers in Turku are seeking direct supply partnerships with primary titanium producers in Baoji to mitigate regional distributor price inflation and secure long-term raw material hedges.
Procurement teams at Turku marine engineering firms are systematically bypassing European intermediary stockists. By sourcing custom-length titanium welding rod runs directly from Jovzi’s manufacturing lines in Baoji, buyers reduce component markups by up to 28% while gaining direct access to original heat logs.
Rising labor costs across Finnish fabrication yards are accelerating the deployment of automated orbital TIG and cold-wire TIG welding. Jovzi satisfies this trend by offering precision-wound D300 (15kg) and D100 spools with zero-tangle tension control, uniform wire diameter tolerances (±0.02 mm), and consistent cast/helix values.
Navigating logistics to Southwestern Finland requires diversified freight options. Jovzi offers expedited air courier routes to Turku Airport (TKU) or Helsinki-Vantaa (HEL) for emergency line-stoppages (3–5 days), alongside sea-freight consolidations directly arriving via Port of Turku or Vuosaari Harbor.
