Embodiment 1

[0011] Embodiment 1: see figure 1 , figure 2 , a method of converging the ground wires of the spiral pre-finishing welding and finishing welding unit. 1) Find the appropriate position for the prepared bus bar 1. For the selection of the position, we choose the shortest straight-line distance from the conductive brush wiring bar and the space The location is enough for the bracket to be installed in the open space, and the bracket is fixed on site; 2) Install the prepared bus bar 1 on the bracket and insulate it well. The connection between the bus bar and the fixed bracket needs to be processed with insulating materials as above figure 1 As shown, the insulation between the bracket and the bus bar must be well insulated. If the insulation is not done well, the whole renovation project will fail); 3) Put the ground wire cable end connected to the welding machine at the lower end of the bus bar and press the connector. Then measure the length of the prepared cable and press th...

Abstract

The invention relates to a ground wire junction method for a spiral two-stage pre-finish welding set. The method includes the steps that (1) appropriate locations are found for prepared busbars, and an occupied lot which has the shortest straight-line distance with a conductive brush connector bar and is sufficient for a support to be installed in spatial position is selected for placement, and the support is manufactured and fixed on site; (2) the prepared busbars are installed on the support to be insulated, and the busbars and the fixed support need to be connected through insulating materials; (3) ground wire cable ends connected out of a welding machine are placed at the lower ends of the busbars, connectors are pressed, then the lengths of prepared cables are measured, the connectors are pressed, and the two busbars are connected in series through the corresponding cables; (4) the distance between the busbars and a welding base wire brush wiring board is measured, the cables are used for manufacturing connecting lines, opening and closing of a ground wire brush need to be considered in the manufacturing process, and allowance is required on the aspect of the lengths of the connecting lines; (5) the connecting cables and earthed brush wiring boards are connected, and all bolts are tightened; and (6) insulativity of all the insulated portions is checked and the process is completed if no problems are found.

Description

technical field [0001] The invention relates to a method for converging ground wires, in particular to a method for converging ground wires of a spiral pre-finishing welding and finishing welding unit, and belongs to the technical field of finishing welding methods. Background technique [0002] During the two-step pre-finishing welding production process, the applicant has improved the production process many times and successfully completed the production task. During the production process of this order, we have accumulated a lot of experience in two-step (pre-finish welding) production and ideas for equipment and process improvement. In daily production, we found that there are certain deficiencies in the products produced by finish welding, such as steel pipes The external shape of the weld at end B (arc starting end) is different from that at end A (arc extinguishing end). The weld seam at end B is a normal weld, but the outer shape of the weld seam at end A is narrow ...
