Participation reward: 2 Wealth. **Correct reward: 9 wealth. For welding grounding devices, lap welding should be used, and the lap length must meet the following requirements: ( ). A. When welding flat bars together, the lap length should be 2 times the width of the flat bar, with welding being performed on no less than three sides. B. When welding round bars together, the lap length should be 4 times the diameter of the round bar, with welding being performed on both sides. C. When welding a flat bar to a round bar, the lap length should be 6 times the diameter of the round bar, with welding being performed on both sides. D. When welding a flat bar to a steel pipe or to an angle bar, the welding should be done on both sides adjacent to the outer surface of the angle bar, or on 1/2 of the length of the steel pipe. Standard: A, C
