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.<br /><br />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.<br /><br />9. The correct answer is a) $34^{\circ }(-19mm)$.<br /><br />Explanation: When preparing welding coupons for V-groove welds with backing, the backing should extend beyond the coupons by at least $34^{\circ }(-19mm)$. This ensures that the backing provides adequate support and stability to the weld joint during the welding process.<br /><br />10. The correct answer is c) at a 15-to 45-degree push angle.<br /><br />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.
