Welding Practice Test

Take this free welding practice exam to get a sample of the types of questions on an actual welding exam.

Subject matter covered in actual AWS and other welding examinations include:  Shielded Metal Arc Welding, Flux Cored Arc Welding, Self Shielded and Submerged Arc Welding, the arc welding processes protected by flux, along with the gas shielded processes, such as Gas Tungsten Arc Welding, Gas Metal Arc Welding and Flux Cored Arc Welding-Gas Shielded. Brazing and soldering are also covered, along with common mechanical and thermal cutting processes that will aid in material preparation and enhance welding fit-up issues.

To prepare for your welding test, see the Welding Practice Exam Kit with 360 Questions with fully explained answers.

1. What is the major function of the coating on an arc welding electrode?
2. Square wave refers to the ____________.
3. Shielding gases are used to protect the molten metal from _______.
4. Weld backing is used with a process that uses a separate flux and electrode to _______ .
5. _________ is the weight of a volume of material compared with an equal volume of water.
6. A medium carbon steel has a carbon content of what percentage range?
7. If a liquid weld pool is at a very high level of energy, at what approximate temperature will the steel begin to solidify?
8. __________ is a groove melted into the base metal next to the weld toe or weld root and has not been filled in.
9. If the weld does not combine with another weld or the base metal it is referred to as:
10. To determine if a welder is qualified, the welder must pass a ________________ test.
11. Which term best describes the operation where a welder or welding operator has control of a molten weld pool and the weld pool has a side to side motion that is transverse to the travel direction?
12. A broken surface is being observed. A small pore or inclusion type discontinuity appears as a round bright area. Which term fits this description?
13. Arc time is:
14. What is the difference between back and backing welds?
15. What NDE process is indicated in the following description? Detects surface discontinuities only. It can also verify fit-up, joint configuration, weld dimensions and profiles.
16. Penetrant Testing uses a penetrating liquid dye which is applied to a properly prepared surface. The dye is pulled into the discontinuity by _______ action.
17. Which of the following is an established norm or requirement issued by the federal, state or local government about technical systems?
18. Before welding can be done to an industrial welding standard, the supervisor needs to verify:
19. Normal pant and shirt material worn around welding should be of what material?
20. What is the minimum oxygen level for a confined space?
