OK Tigrod 13.26 is a copper-coated, low alloyed, nickel copper (0,8% Ni, 0,3 %Cu) rod for the GTAW of weathering steels such as COR-TEN, Patinax, Dillicor etc. The weld metal composition and mechanical properties also make this product suitable for welding high-strength steels with a minimum yield strength of less than 470 Mpa.

Corten TIG Wire FAQs

Questions buyers ask when choosing and using TIG filler wire for weathering steel.

Will the weld match the colour of the plate as it weathers?

Often it will come close, but it depends on the filler, the joint and the exposure. Filler metals that are alloyed to match weathering steel generally give the best and quickest colour match. A plain carbon steel weld usually looks different at first and corrodes at a different rate, although over a long time all welds tend to take on a patina.

Thin plate tends to blend better because more of the parent metal mixes into the weld. If appearance matters, such as architectural or artistic work, use a matching alloyed filler, make a trial weld and let it weather before committing to the full job.

Do I have to use weathering filler for every pass on a weld?

Not always, but it depends on the joint and the design. Bridge guidance notes that weld metal from matching alloyed consumables becomes copper-rich, which can cause difficulties if the weld is also restrained. It recommends plain carbon-manganese consumables only in limited cases, such as single-run fillet welds and butt welds made with one run from each side, where dilution from the plate supplies enough alloy for corrosion resistance. Some filler suppliers also describe using carbon steel filler for most of a large multi-pass weld and an alloyed filler on the final layers where the code permits.

This is a design and procedure decision, not a buyer's choice. Follow the welding procedure specification and the designer's requirements.

What polarity and settings suit this TIG wire?

Like other steel TIG filler, it is normally used with DC electrode negative (DC-) and a pure argon shield, with a tungsten electrode suited to DC, kept clean and ground lengthways to a point. Polarity and gas are the same as for ordinary steel TIG, so the usual machine set-up applies.

Current, travel speed and filler diameter then depend on the plate thickness, joint type and position. Start from the machine and consumable maker's guidance, and prove the settings on an offcut of the same plate before welding the real joint.

How do I decide whether weathering steel needs preheating?

There is no single temperature. Steel makers explain that the need for preheat depends on the steel's carbon equivalent, the hydrogen level of the process or consumable, the heat input and the combined thickness of the joint. Low-hydrogen processes and consumables reduce the risk of hydrogen cracking and often reduce the need to preheat.

TIG is a low-hydrogen process when the rod and joint are clean and dry, but thick or heavily restrained joints can still need preheat. Take the figure from your welding procedure, the plate certificate and the relevant welding standard rather than from a general rule of thumb.
