WELDING 4 TIG AND CO2 WELDING - Practice Mode
1) Which is the non consumable electrode is used in GTAW process?
Correct Answer: Tungsten electrode
4) What is the range of PWHT for stainless steel grade 316L?
Correct Answer: 1035 Degree - 1107 Degree Centigrade
Explanation:
Rise or fall is the difference in elevation between two points in a survey. In your case, if the backsight reading taken on a benchmark (B.M) is 2.045 meters and the foresight reading on a point is 2.68 meters, the rise or fall is:
Rise/Fall = Foresight Reading - Backsight Reading
Rise/Fall = 2.68m - 2.045m
Rise/Fall = 0.635m
So, in this case the foresight point is 0.635m higher than the B.M
5) Which is the welding process that produces the arc with bare filler rod shielded by CO2 gas?
Correct Answer: MAG welding
