[MW:23175] Impurities on weld-GTAW

This kind of problem comes due to copper coating of filler wire. Copper coating is provided to protect filler fire from corrosion. As copper has lower melting temperature due to which it sodifies last. This is not a severe defect. Just remove it after completion of joint.
