Weld Defects and Causes Crossword Puzzle

QUESTIONS LIST:

• spatter : too low voltage and too high amperage current settings.
• slag inclusion : incorrect electrode angle.
• misalignment : the too-rapid welding process.
• crack : poor ductility or contamination of given base metals.
• distortion : varying temperature gradients during welding.
• undercut : using too high voltage or too fast weld speed, causing melting at the top edge.
• porosity : inadequate coating of electrode or use corroded electrode.
• external defect : usually detectable via visual inspection.
• internal defect : occurs within the metal material.
• overlap : using the wrong welding technique.
