Across
- 2. Length of an Arc = θ × r,
- 3. material which has a relatively large number of loosely bonded electrons which may move freely when voltage (electrical pressure) is applied
- 4. join metals using a variety of techniques and processes
- 5. depression in the weld face at the termination of a weld bead
- 7. utilizing an electric arc and filler metal with a stick electrode or wire to join materials together.
- 8. welds
- 10. a process of overlapping weld beads merging to produce even surfaces.
- 13. used to create a beveled opening in a weld joint before welding to achieve the necessary penetration

Down
- 1. SMAW is a manual welding process using a coated electrode
- 6. an arc welding technique which allows for filling a wide, flat joint or welding thick metals by adding a weave pattern to cover a larger surface area.
- 7. contact between the rod electrode and workpiece ignites the arc.
- 9. the process of joining two pieces of metal together when they are perpendicular or at an angle
- 11. current a type of electrical current, in which the direction of the flow of electrons switches back and forth at regular intervals or cycles
- 12. the joining of two metals using pressure and electrical current, for a set length of time, through the area of the metal to be joined
- 14. When you turn on a welding machine, an electrical circuit is formed.
- 18. welding using the heat of an arc as a heat source.
- 19. the percentage of time that a machine will safely operate (or weld), within a certain time period, at a given amperage
- 22. fusion welding process whereby electrons are generated by an electron gun and accelerated to high speeds using electrical fields
