Rising StarAutomatic flash butt welding machineThe requirements for the end face of the workpiece are not strict, so the process of grinding the end face of the workpiece can be eliminated, simplifying the operating steps and improving production efficiency. Because the contact area is small during flash, the current density at the contact point is large, the heat is concentrated, and the heating is rapid, so the heat affected zone is small, the joint is small and of good quality, the preheating method can be used, and larger cross-section steel bars can be welded on a smaller power flash butt welding machine. For example, 150KVA can butt a workpiece with a cross-sectional area of 10,000mm2, so flash butt welding machines are becoming more and more popular.
The operation of the automatic flash butt welding machine does not require high personnel, and the operation is simple. The process is as follows:
1. Operation process: Inspect equipment → select welding process and parameters → test welding and make simulated test pieces → submit for testing → determine welding parameters → welding → quality inspection
2. Continuous flash butt welding process: Close the circuit → flash (the end faces of the two workpieces are in slight contact) → continuously flash and heat to the melting point (the end faces of the two workpieces are flashing while rapidly contacting with heat transfer) → charged upsetting → push without electricity.
3. Preheat flash butt welding process: Close the circuit → Intermittent flash preheating (the end faces of the two workpieces alternately contact and separate due to heat transfer) → Continuous flash heating to the melting point (the end faces of the two workpieces flash while rapidly contacting with heat transfer) → Electric upsetting → Pushing without electricity 4. Flash-preheat flash butt welding process: Close the circuit → one flash flash to flatten the end faces (the end faces of the two workpieces flash while rapidly contacting with heat transfer) → continuous flash preheating (the end faces of the two workpieces alternately contact and separate with heat transfer) → two consecutive flashes to heat to the melting point (the end faces of the two workpieces flash while rapidly contacting with heat transfer) → charged upsetting → push without electricity.
