Common Defects of Spiral Welded PipesThe main cause of the bubbles in the center of the weld bead is hydrogen is concealed within the weld metal as bubbles. Thus, to eliminate this defect, remove the wire and weld the rust, oil, water, moisture, and other things, and then fully dry the flux to remove moisture. Furthermore, a higher current slows the solidification rate of liquid metal, limiting welding speed.
