Figure RQ01 8. The groove weld in Figure RQ01 is a __ a) single V-groove b) single bevel groove c) double V-groove d) double bevel groove 9. When proparing welding coupons for V-groove welds with backing, the backing should exten beyond the coupons by at least __ a) 34^circ (-19mm) b) 12^circ (-13mm) 14^ast (-6mm) d 18^-(-3mm) 10. When using stringer beads on V-groove welds in the vertical position (3G) keep the electrode __ a) always at a0-degree push angle b) ata 0-to 10-degree push angle c) ata 15-to 45-degree push angle d) alwaysata660-degree push angle

8. The correct answer is c) double V-groove.Explanation: The groove weld in Figure RQ01 is a double V-groove, which means it has two V-shaped grooves on opposite sides of the weld joint. This type of weld is commonly used in structural steel welding to provide additional strength and stability to the joint.9. The correct answer is a) .Explanation: When preparing welding coupons for V-groove welds with backing, the backing should extend beyond the coupons by at least . This ensures that the backing provides adequate support and stability to the weld joint during the welding process.10. The correct answer is c) at a 15-to 45-degree push angle.Explanation: When using stringer beads on V-groove welds in the vertical position (3G), the electrode should be kept at a 15-to 45-degree push angle. This angle allows for proper control of the electrode and ensures that the weld metal is deposited evenly along the joint.
