AWS CRWT Practice Questions - AWS Certified Resistance Welding Technician (CRWT) Exam [aws-crwt] - AWS CRWT Practice Questions - AWS Certified Resistance Welding Technician (CRWT) Exam [aws-crwt]

Question 1

In resistance welding, heat is generated primarily by which physical principle?

Arc plasma radiation at the electrode tip Joule heating (I squared R t) as current passes through the workpieces Induction heating from an external coil Friction between the electrodes and the sheet

Correct Answer:

Joule heating (I squared R t) as current passes through the workpieces

Question 2

According to AWS C1.1M/C1.1, which location in a resistance spot weld stack-up typically has the highest resistance at the start of the weld cycle?

Bulk resistance of the upper sheet Bulk resistance of the lower sheet Faying (sheet-to-sheet) interface Electrode shank resistance

Correct Answer:

Faying (sheet-to-sheet) interface

Question 3

The three primary process variables that define a resistance spot welding schedule are:

Voltage, gas flow, and wire feed Current, electrode force, and weld time Travel speed, arc length, and polarity Preheat, interpass, and post-weld heat temperatures

Correct Answer:

Current, electrode force, and weld time

Question 4

On a resistance spot welding lobe diagram, the two axes plotted are usually:

Electrode force versus electrode diameter Welding current versus weld time Voltage versus travel speed Hold time versus squeeze time

Correct Answer:

Welding current versus weld time

Question 5

The upper boundary of a resistance spot weld lobe is generally defined by:

The smallest acceptable nugget diameter The onset of expulsion (molten metal ejection) Minimum electrode life of 2,000 welds The melting point of the electrode copper alloy

Correct Answer:

The onset of expulsion (molten metal ejection)
