Hello,
I'm studying for my CWI exam. I'm using the AWS Certification manual for Welding Inspectors, Code No.CM:2000. My question is that there are a few answers that contradict the text material. I don't uderstand why this would be. Example: Q10-58 Asks which processes use electrode EWTh-1? I believed and it is stated in the text that both PAW and GTAW use tungsted electrodes. The correct answer in the book is (ONLY) GTAW. I chose both, which was wrong...
There are a few more. Q10-69: It is written that SAW has the highest rate of deposition. Yet the correct answer is ESW?
Question Q8-23: asks how many lb/h with a SAW process is 19.7 kg/h? My math says the answer is
43.4310731 lb/h. The correct answer in the manual is 43.34lb/h. !!! Huh? Am I missing something. Or are these a type of trick questions?
If anyone can help Thank You!
Tim
