The welding of grounding devices should use lap welding, and the lap length must meet the following requirements ( ). A. The overlap between flat bars should be 2 times the width of the bar, with welding carried out on no less than three sides. B. The overlap between round bars should be 4 times the diameter of the bar, with welding performed on both sides. C. The overlap between a flat bar and a round bar should be 6 times the diameter of the round bar, with welding carried out on both sides. D. When welding a flat bar to a steel pipe or to an angle bar, welding should be done on the two sides adjacent to the outer surface of the angle bar, or on 1/2 of the length of the steel pipe
The welding of grounding devices should use lap welding, and the lap length must meet the requirements specified in (A C). A. The overlap between flat bars should be 2 times the width of the flat bar, with welding carried out on no less than three sides. B. The overlap between round bars should be 4 times the diameter of the round bar, with welding performed on both sides. C. The overlap between a flat bar and a round bar should be 6 times the diameter of the round bar, with welding carried out on both sides. D. When welding a flat bar to a steel pipe or to an angle iron, the weld should be made on both sides adjacent to the outer surface of the angle iron, or 1/2 of the length of the steel pipe away from its outer surface
The welding of grounding devices should use lap welding, and the lap length must meet the requirements specified in (A, B, C, D).

The welding of grounding devices should use lap welding, and the lap length must meet the following requirements (ABCD). A. The overlap between flat bars should be 2 times the width of the flat bar, with welding carried out on no less than three sides. B. The overlap between round bars should be 4 times the diameter of the round bar, with welding performed on both sides. C.
