  1. 3. A relatively flat bead contour used when the bead is to be ground or machined
  2. 6. The process of creating a weld pool of molten base metal and advancing it along a line
  3. 7. Forming a line of fused weld metal along a line or a joint of the weldment
  4. 13. Creating a pool with molten base metal and advancing it along a line, maintaining a consistent width
  5. 15. The travel angle used during backhand welding when the welding end of an electrode or a gas flame points opposite the direction of travel
  6. 16. The angle between a line perpendicular to the major workpiece surface and a plane determined by the electrode axis and the weld axis. In a T-joint or a corner joint, the work angle is measured from a line perpendicular to the nonbutting surface
  7. 17. The travel angle used during forehand welding, when the welding end of an electrode or a gas flame points in the direction of travel
  8. 18. The thinning of the base metal along the toe of the weld
  9. 19. The small molten volume of metal under the torch flame or electrode, prior to its solidification as weld metal
  10. 20. Foreign matter introduced to and remaining in, welds or castings
  11. 21. The forward edge of the weld pool
Down
  1. 1. A condition in which the weld pool flows onto the base metal surface and is not fused into the base metal
  2. 2. A crescent-shaped weld pool, which indicates that the base metal surfaces have melted enough to create a well-fused weld
  3. 4. A weld bead with a surface that curves inward, toward the root of the weld
  4. 5. An enlarged root opening that looks like an old-fashioned keyhole. A properly formed keyhole indicates both pieces of metal are melting
  5. 8. Refers to a welding rod that becomes stuck in the weld pool
  6. 9. A method used when the welding end of an electrode or a gas flame is pointed in a direction opposite the direction of travel.
  7. 10. The angle between a line perpendicular to the weld axis and the axis of the electrode. The angle is measured in a plane determined by the electrode axis and the weld axis
  8. 11. A weld bead with a surface that curves outward, away from the root of the weld
  9. 12. A method used when the welding end of an electrode or a gas flame is pointed in the direction of travel
  10. 14. A welding technique in which concentrated heat penetrates the workpiece, leaving a hole at the leading edge of the weld. As the heat source moves on, the keyhole is continually formed and filled
