What are the steps of using butt welding machine?

The butt welding machine is also called current welding machine or resistance bump welding machine. Using the resistance between the contact surfaces of two workpieces, the contact surfaces of two butted metals are instantly heated to melt and fuse through low voltage and high current.

What are the advantages of the butt welding machine?

1. The welding efficiency is high. Because the butt welding machine is compressed by the double force cylinder, its response speed is significantly faster than that of the hydraulic cylinder.

2. Automatic centering function. Ensure that the distance between the two ends of the pipe column and the two chip head ends is the same before welding, so as to ensure the same amount of burning at both ends.

3. Convenient operation and maintenance services. Because there is no hydraulic station, the product has fewer debugging points and failure points, and there will be no oil leakage.

4. Low requirements on the power grid. Only 250KVA power grid can be satisfied.

5. High welding accuracy. Using programmable controller PLC and imported stepping to control the flashing process, it can accurately set the burning amount and burning speed; the welding current is controlled by the microcomputer resistance welding controller. The center distance error of the film head after welding can be It is controlled within ±0.2mm, which is convenient for subsequent assembly welding.

6. Energy-saving. The butt welding machine uses two 125-KVA resistance welding transformers as power source, pneumatic compression, accumulation and no hydraulic station.The UN-250AB welding machine can save up to 78% of power compared to two other 315-KVA single-phase AC welding transformers and two welding machines with a performance of 18-KVA hydraulic stations.

What is the working principle of the butt welding machine?

The drum welder actually uses the resistance to generate heat when the butt welding machines are in contact with each other to achieve the purpose of heating the butt welding machine and melting the metal surface. The weld seam is formed under the condition that the solid phase metal of the butt welding machine is plastic. The grain, welding structure and composition are close to basic metals, making it easier to achieve. In the flashing process, the self-protection function is to suck air and reduce metal oxidation, so that there are fewer errors such as welding locks and incomplete penetration.

What should the operator know when using the butt welding machine?

1. The staff should be familiar with the welding process of the butt welding machine:

Continuous flash welding: continuous flash, upsetting, and heating treatment on the welding machine after upsetting;

Preheating flash welding: one flash, burning preheating, two flashes, upsetting.

2. The operator must be familiar with the mechanical and technical properties used (such as the number of transformer stages, the maximum welding section, the number of welding, the maximum upsetting force, the maximum feeding stroke), and the location and application of the main components.

Overall, the important role of butt welding machine in our daily lives is perceived by more and more people. WELPING strives to offer high quality butt welding machine at reasonable prices, efficient production times and the most professional customer service.
