This arc is struck between the metallic workpiece and continuously fed tubular cored consumables filler wire, with both the wire and metallic workpiece melting together to form a weld joint. Flux core wire eliminates the need for an external gas supply because it has internal shielding properties. Flux core welding is great if the welding is outside and where there might be a breeze as gas won’t blow away. This process is best for welding thicker material with a single pass. 0 Reply Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp Leave an answerCancel replyYou must login or register to add a new answer.
