Titanium Welding Wire for Industrial Corrosion Parts

You build a titanium tank. Or a pipe. Or a heat exchanger. It costs more than stainless. But you do it because stainless failed last time.

Then you weld it.

And if that weld corrodes, you just wasted your money.

Titanium welding wire for industrial corrosion parts is what separates a good corrosion job from a call-back. The base metal lasts decades. The weld has to last just as long. No shortcuts.

Not every corrosion environment is the same. One wire doesn't fit all.

ERTi-2 is pure titanium. Grade 2. This is your everyday corrosion wire. Seawater. Dilute sulfuric. Nitric acid. Chlorides. Most chemical plants run on this.

ERTi-12 has molybdenum and nickel. Small amounts. Makes a big difference in hot brine and reducing acids. Desalination plants use this. So do hot seawater heat exchangers.

ERTi-5 is the strong one. Ti-6Al-4V. Same corrosion resistance as ERTi-2 but almost three times stronger. Use it when your corrosion part also has to hold weight or pressure.

Titanium welding wire for industrial corrosion parts means picking the right one. Get it wrong and the weld goes first.

• Diameter range: 0.8mm to 3.2mm. Most common are 1.2mm and 1.6mm.
• Surface: pickled and clean. No oil. No oxide. No drawing compound.

Pick up a spool of titanium welding wire for industrial corrosion parts. Here's where it goes.

• Chemical plant maintenance. Someone drains a reactor, finds a cracked weld, grinds it out, and welds it back with ERTi-2. Back online same day.
• Desalination plant construction. High-temp brine piping. Every joint gets ERTi-12. One bad weld and the whole line corrodes at that spot.
• Marine repair. Seawater cooling lines on a platform. Old welds failed. New welds with ERTi-2. Good for another 15 years.
• Pharmaceutical shop. Cleanroom welding of titanium vessels. ERTi-2. No contamination. No rust particles.
• Paper mill. Bleach plant piping. Chlorine dioxide service. ERTi-2 or ERTi-12 depending on temperature.

Three mistakes happen over and over.

First, no back purge. Titanium needs argon on both sides. Front and back. Back purge isn't optional. Without it, the back of the weld oxidizes and cracks later.

Second, dirty hands. Welders touch the wire with bare fingers. Skin oil has chlorine. Chlorine causes porosity. Wear clean gloves. Don't touch the filler metal.

Third, wrong filler. Using ERTi-2 on a Grade 12 job. The base metal resists crevice corrosion. The weld doesn't. The weld fails first.

Titanium welding wire for industrial corrosion parts works fine when you follow the rules. Break the rules and it fails like anything else.

After you weld, look at the color.

Shiny silver. That's perfect. Run it.

Light straw or gold. Acceptable for most corrosion work. Not ideal but fine.

Blue or purple. Bad shielding. Too much oxygen got in. Might pass but risky.

White or grey. Cut it out and redo. It will corrode. It will crack. Don't leave it.

For corrosion parts, don't accept blue welds. Silver or straw only.

This wire comes clean. Keep it clean.

The spool has a plastic bag. Leave it on until you're ready to weld. If you leave the spool open on a shop bench for a week, it picks up dust and oil.

Straight cut lengths come in sealed tubes. Open one at a time.

If wire gets dirty, wipe with acetone. Let it dry completely before welding.

Corrosion parts cost money. Titanium isn't cheap. But replacing a failed weld in a chemical plant costs more than the original part. Downtime. Labor. Lost production.

Titanium welding wire for industrial corrosion parts is cheap compared to a second shutdown.

ERTi-2 for most jobs. ERTi-12 for hot brine. ERTi-5 for strength.

Clean wire. Back purge. Match the filler. That's it.
