These are actual questions from our online practice test.

We have included a question from each chapter of the test. Every question will be multiple choice. The answers are not included with the sample.

Sample Questions

# Chapter Title Question
1 Welding Processes, Fillet Welds and Grove Welds You should only remove back-up strips when?
2 Welding Processes, SMAW, FCAW and Electrodes The electrode for GMAW is what?
3 Welding Processes, ER80SX, AWS, SMAW Electrodes and Slot Welds Holding ovens should be used to protect which electrode type(s) from moisture ______________.
4 Welding Processes, American Welding Society Numbers, RGA 277 and Specifications The maximum moisture content should be limited, by the weight of____% for ANSI/AWS A5.1 OR A5.5 low hydrogen covering.
5 Welding Processes, Stud Welding, Double Bevel Groove Welds, Butt Weld and ASTM On a direct butt weld the maximum reinforcement is ___ inch.
6 Welding Processes, Preparation, SW Welding, Low Hydrogen Electrode, Temperatures and AC/DC Why is it a mistake for a welder using E12018 electrodes if he started a project an hour and 1/2 ago with electrodes from a new can?
7 Welding Processes, F6OEL4OK Solid Wire Electrode and Root Pass In the flat position the largest electrode permitted is 5/16".
8 Oxyacetylene Welding Stainless steel ____________ be welded with an oxy/acetylene torch.
9 Pipe Welding A pipe anchor support is a rigid device that completely restricts pipe movement in all three dimensions while bearing the weight, side, and thrust loads. It is designed to prevent essentially all pipe rotation and displacement at the point of application.
10 Brazing Welding _______________ is a process in which two or more metal items are joined together by melting and flowing a filler metal into the joint, the filler metal having a lower melting point than the adjoining metal.
11 Sheet Metal Frabrication What is the term used to describe the process of using welding to join sheet metal?
12 Arc Welding A __________________ is a device that provides an electric current to perform welding. Welding usually requires high current (over 80 amperes) and it can need above 12,000 amperes in spot welding.
13 Additional Welding Questions The operating cost of MIG welding is lower than Stick welding because of the time savings, and because there's virtually no waste of filler metals (50 lbs. of MIG welding wire yields approximately _______ lbs. of deposition, as compared to Stick welding where as much as 25% of each electrode is discarded as stubs.)
14 Testing and Inspection X-rays and gamma radiation have wavelengths shorter than _________ nanometres (nm).
15 Tools An item that is used for welding is a ___________ top welding table with angle iron or sturdy pipe legs.
16 Materials A Hobart Victor Oxy/Acetylene Heating Tip can be used with oxy/acetylene or propane. Acetylene required for welding. Propane can be used for brazing, soldering or heating.
17 Safety What should construction employees wear when working at night?
18 OSHA, Rules of Construction, General Safety and Health Provisions

1926.57(g)(2),  Wherever _____________________________ or buffing is performed, and employee exposure, without regard to the use of respirators, exceeds the permissible exposure limits prescribed in 1926.55 or other pertinent sections of this part, a local exhaust ventilation system shall be provided and used to maintain employee exposures within the prescribed limits.
