Across
  1. 6. These metals do not have any iron, such as titanium
  2. 7. A measure of the electrical current, which determines the heat of the weld
  3. 8. Small metal particles ejected from the welding arc that are not part of the weld
  4. 11. The rapid cooling of metal using water, air or oil
  5. 12. The width of a piece of metal removed by cutting
Down
  1. 1. A defect where the weld digs into the base metal, reducing the weld's strength
  2. 2. the slow cooling of the metal to reduce internal stresses, make the material softer and change ductility
  3. 3. Direct Current Electrode Negative
  4. 4. This material cleans metals to prepare them for welding
  5. 5. Direct Current Electrode Positive
  6. 9. A metal made from two or more combined elements
  7. 10. An electrode conducts the electrical current through a work piece to create the weld
