Across
- 3. The distance between the two pieces at the weld root
- 8. The distance from the contact tube to the surface of the work
- 10. An enlarged root opening that looks like an old-fashioned keyhole. A properly formed keyhole indicates both pieces of metal are melting
- 11. A method used when the welding end of an electrode or a gas flame is pointed in a direction opposite the direction of travel
- 12. The first weld pass made into the root of the joint
Down
- 1. The travel angle used during backhand welding when the welding end of an electrode or a gas flame points opposite the direction of travel
- 2. A method used when the welding end of an electrode or a gas flame is pointed in the direction of travel
- 4. Voltage is present in an electric circuit even when no current is flowing
- 5. Material is placed beyond the root opening to control penetration and prevent a hot-shortness hole. The backing may be machined to control the shape of the penetration bead
- 6. The length of the unmelted electrode extending beyond the end of the contact tube in GMAW, FCAW, and GTAW. Also called electrode stick-out
- 7. The distance from the end of the nozzle to the base metal
- 9. The travel angle used during forehand welding, when the welding end of an electrode or a gas flame points in the direction of travel
