1. Due to the slight rust of the wetted core, it will not affect the performance.
2. The welding wire is seriously damaged by the rust, and can be used for degraded or used for general component welding.
3. The chromium carbide wear-resistant welding wire is seriously damp, and even the paint has rust. Although such a wire is dried, it still produces pores or high diffusion hydrogen content during welding, so it can be used.
