This was Przemek's question when we talked about welding. He didn't know how to say "elektroda" and here in English it's practically the same expression as in Polish. It's an electrode.
By the way, can you briefly explain what the difference between welding and soldering (two very similar joining techniques) is?

So... as I said at last English lesson - I think the difference is in temperatures of melting of tin and welding electrode or welding wire. The temperature of melting tin during soldering is lower then temperature of melting joined materials. So we melt only the tin - and in this way we join these materials. During welding as well joined materials and electrode or welding wire is melted. So in the heat affected zone we have the mixture (or alloy) of welding wire and joined materials. So welding is much stronger than soldering.
ReplyDeleteExcellent explanation - thanks!
