Copper bus manufacturerCan you explain what a copper busbar butt welding machine is? A copper busbar butt welding machine is actually just a butt welding machine. A butt welding machine uses low voltage and high current to make the surface of the metal instantly red-hot and reach its melting point, so that the surfaces of the two metals melt and fuse together. It is mainly used for fastening. So, do you know the advantages of a butt welding machine? If you don't, that's okay. Let's take a look together with the editor.

The advantages of butt welding machines are as follows: 1. High welding efficiency. Because workpiece clamping uses a force-double cylinder, its response speed is significantly faster than that of hydraulic cylinders. Operation and maintenance services are convenient. Since there is no hydraulic station, there are fewer debugging and fault points for the product, and oil leakage and similar issues do not occur. 2. Low requirements for the power grid. Only a 250KVA power grid is sufficient. High welding precision. Uses programmable controller PLC and imported stepper motors to control the flash process, allowing precise setting of sintering amount and speed; Soldering current is controlled via a microcomputer solder mask controller. The center distance error of the post-weld sheet can be controlled within ±0.2mm, facilitating subsequent chip assembly and welding. 3. Automatic centering function. Ensures consistent spacing between both ends of the column and the two heads before welding, thereby guaranteeing consistent solder rates at both ends. 4. Energy saving. The radiator flash butt welding machine uses two 125KVA solder mask transformers as the power source, with pneumatic clamping and top forging, and no hydraulic station. Compared to other machines that use two 315KVA single-phase AC solder mask transformers and two 18KVA hydraulic stations, the UN-250AB welding machine can save up to 78 degrees of power. The correct usage process for the butt welding machine is as follows: (1) Welding operators and cooperating personnel must wear protective equipment as required. Safety measures must be taken to prevent electric shock, fire, and other accidents. (2) The butt welding machine should be installed indoors and have reliable grounding or neutral connection. The length of the welding wire should not exceed 30m; if the wire needs to be extended, the cross-section should be increased accordingly. When multiple butt welding machines are installed side by side, the distance between them must not be less than 3m, and they should be connected to power grids of different phases, each with its own knife-type switch. Within 10m of the welding site, oil, wood, generators, and other flammable or explosive materials must not be stacked. (3) The contact points and electrodes of circuit breakers should be regularly polished, and all bolts connecting the secondary circuit should be tightened regularly. Cooling water temperature should not exceed 40°C, and drainage should be adjusted according to air temperature. When welding longer rebar, brackets should be set up to assist operators handling rebar, and care must be taken to prevent spark burns during welding. (4) Flame-retardant baffles should be installed in flash areas; no other personnel are allowed inside during welding. During winter welding, indoor temperature should not be lower than 8°C. After operation, all cooling water inside the machine should be drained. (5) Before starting work, check and confirm that the butt welding machine's pressure mechanism is flexible, the fixtures are secure, and there are no leaks in the pneumatic or hydraulic systems. Welding can only proceed after everything is functioning normally. Before welding, adjust the secondary voltage according to the cross-section of the rebar to be welded. Do not weld rebar exceeding the diameter specified by the butt welding machine.
