A18 is my normal choice, I have a load of 309 which i am not using so am looking at ways of using it up.
It’s irrelevant if it’s a custom motorcycle frame or a patch on an Astra wheel arch it’s a total waste to use a consumable like that on carbon steel not to mention the wrong consumable from a composition match POV. It might be fine it might crack.Waste?
WASTE?
we are talking custom motorcycle frames here, how could it be a waste?? Lol.
It does give a luvverly weld and flows good too, which is why it would look good adorning a motorcycle frame.
Well no mate. Using a wire matched to the parent material heavily reduces the risks of problems. That’s the whole idea. Using stainless consumables on mild steel only (even over alloyed ones) can run the risk of a joint becoming martensite which is a very hard and brittle structure. If you want your frame to look nice then bronze weld or tig braze it.But the same can be said of any weld surely, it might crack.
Are we talking hot cracking or cold cracking?
