Can Bai Gang self-shielded welding wire be filled?

Yes Because the cost of Bai Gang self-shielded welding wire is higher, Bai Gang self-shielded welding wire can be filled. Self-shielded welding wire refers to arc welding without shielding gas or flux, so as to obtain qualified welding wire. Self-shielded flux-cored wire is to put powder and metal powder used for slagging, gas production and deoxidation into steel skin or coat it on the surface of welding wire. During welding, the powder becomes slag and gas under the action of arc, which plays the role of slagging and gas production protection, and no additional gas is needed.
