I know there are trace elements in the welding wire, but how can I identify them?
1 、 welding wire required smooth feeding, diameter precision requirements.2. in order to meet the requirements of welding, the composition of the welding wire is slightly different from that of the ordinary stainless steel.
It doesn't make much difference. The welding wire is the steel wire, and the steel wire is not necessarily the welding wire
Generally look at their gloss and hardness difference. Otherwise, you'll be able to distinguish between chemicals
