What are these rods please?

[Carl Wilson]

Hi all. Wonder if you can help me. I found these tig rods in stock at work today. They seem to be some sort of aluminium bronze. They have a flux coating on them as well.

I know that they are used in marine engineering for welding copper/zinc/aluminium

alloy pipework for seawater heat exchangers etc. Alloy CZ110 is used for pipes in these applications. It includes arsenic to prevent zinc leaching out. I don't believe the rods contain arsenic.

I'm just wondering why these rods need flux? Can I use these rods in a tig brazing way for repairing cast iron, say?

Thanks!

I doubt they would be any good for that if you decide not to keep them let me know

 

[Carl Wilson]

They are not mine to sell or give. To do so would be theft.

I'm mainly wondering why they are fluxed? Surely the argon takes care of that?

Think these are the same. Gives you all info you need.

The flux is probably on them to aid welding of alloys with zinc.

It looks to basically be an Aluminium-Bronze consumable with a fair bit of manganese, plus the flux coating.

No good for cast iron mate. The only application I can see for those rods is the welding of the pipes they are designed for.

Dont think ive ever heard of Aluminium Brass....thats Wilhelmson (or whatever its called) is a ship supply outfit

 

[Carl Wilson]

Yes Wilmhelmsen is Norwegian. They supply gas and welding equipment/consumables under the brand Unitor. When I say at work, I mean on a ship.

 

[Hitch]

AluminiumBronze works well for cast, but not if the rods are covered in flux.

 

[Liquid Metal]

Is there a flux coating on them, or is it inside the rod like a flux core?
Have never used them myself, but im sure there are some types of rod that have a powdered flux in the core of them for some applications in which the flux helps to drag any impurities out of the puddle and float it to the top.

 

[Carl Wilson]

The flux isn't in the core, it is in circumferential grooves along the length of the rods.

oxy acetylene rods by the description
for brazing spigot and socket welds

 

[Carl Wilson]

They aren't oxy acetylene. They are tig welding rods used for welding aluminium bronze pipework that has some zinc in the alloy blend. It's used in highly corrosive environments, like seawater coolers. This much I now know.

 

[zeppelin builder]

maybe the flux helps to coat the surface and keep the alloying elements from vapourising

ali bronze was popular in engine rooms for cooling lines

Is it an oldish ship your on,

Yorcalbro was commonly used on high quality ships in the 70 and 80s, but was bloomin expensive, then they started using cunifer (spelling), and of course the cheap far east option of badly galvanized mild steel, lasts about as long as the warrenty.

I learnt alot about pipe welding on 80s built Korean ships.

Unitor is just a brand everything with their name on it, is made by others, from what I recall.

Bohler make their rods.

 

[Carl Wilson]

It's brand new but the ship they came from was 30 years old.

thought Id seen the packaging somewhere
