  • Butt welding machine application range

    Butt welding machine application range

    20 Sep 2022

    Butt welding machine is also called resistance butt welding machine. It is mainly suitable for high-speed and large-volume operations. It uses resistance butt welding method, which has high electric energy utilization rate and good welding effect. The small size reduces the welding defect rate to a minimum. The equipment is used for welding wire and cable, bicycle basket, enameled wire, steel wire products, luggage frame and flat wire products. Structure and Features: The welding machine transformer adopts a vertical one-way shell-type mechanism, which has high welding efficiency and low loss. The use of different welding dies can be replaced according to different welding objects, which is more convenient. The inside of the equipment is transformed from 380V voltage to 36V electricity, with good safety performance. Suitable for welding of various metal materials such as carbon steel, stainless steel, aluminum alloy, copper alloy, etc. Butt welding machine is very useful between steel ...

  • Butt welding process can be divided into resistance butt welding and flash butt welding

    Butt welding process can be divided into resistance butt welding and flash butt welding

    13 Sep 2022

    1. Butt welding process According to the working principle of the butt welding machine, the butt welding process can be divided into two types: resistance butt welding and flash butt welding: Resistance butt welding Resistance butt welding is to heat the end joint of the steel bar to a plastic state and then cut off the power supply, and then heat it again to achieve a plastic connection. This welding process is easy to produce oxidation and slag inclusions at the joints, and requires the cross-section of the steel bars to be smooth and smooth. Flash Butt Welding Flash butt welding refers to the ejection of molten metal particles from the end joints of rebar during the welding process, presenting sparks (ie, flashes). When the molten metal is sprayed, it also brings out oxides and slag inclusions, so that the quality of the butt welded joint is good, so it is widely used, especially for the butt joint of low carbon steel and low alloy steel. 2. How to use The following items should be ...

  • Three factors affecting the efficiency of spot welding machine

    Three factors affecting the efficiency of spot welding machine

    06 Sep 2022

    Welding current Since the heat generated by the resistance is proportional to the square of the passing current, the welding current is an important factor in generating heat. Butt welding machine. The importance of welding current does not simply refer to the size of welding current, but also the level of current density. ※Nugget: refers to the metal part that solidifies after melting at the joint during lap resistance welding. pressure The pressure in the welding process of the spot welder is an important factor in the heat generation. Pressurizing force is the mechanical force applied to the welding place. The contact resistance is reduced by the pressurizing force, and the resistance value is made uniform, which can prevent local heating during welding and make the welding effect uniform. Power-on time The power-on time is also an important factor in generating heat. The heat generated by power-on is released by conduction. Even if the total heat is constant, due to the different p...

  • The main component of the butt welder is a step-down transformer

    The main component of the butt welder is a step-down transformer

    01 Sep 2022

    The main component of the butt welding machine is a step-down transformer, and the two ends of the secondary coil are the workpiece to be welded and the electrode. When working, the arc is ignited, and the electrode is fused into the gap of the workpiece at the high temperature of the arc. Because the iron core of the welding transformer has its own characteristics, it has the characteristics of a sharp drop in voltage, that is, the voltage drops after the electrode is ignited; when the electrode is stuck and short-circuited, the voltage drops sharply. Next, the editor will introduce the principle of butt welding machine and the advantages of butt welding machine. Butt welding machine principle What the butt welding machine uses is that the resistance will generate heat when the workpiece is in contact with each other, so as to achieve the purpose of heating the workpiece and make the metal surface melt, and the weld is formed under the condition of plastic deformation of the solid pha...

    Astigmatism butt welding machine should pay attention to what

    22 Aug 2022

    1. Before using the flash butt welding machine, check whether the rated voltage of the winding and the power supply voltage are consistent (380V or 220V), and check whether the wiring of the terminal board is correct. If the flash butt welding machine is put into use for the first time or has been used for a long time, a 500V megohmmeter should be used to measure the mutual between the winding and the insulation resistance on the magnetic core should not be less than 0.5MΩ. 2. The flash welder is on the side, the terminal board nut, copper wire and wire on the secondary side must be in close contact and reliable. If the contact is not good, burn the bolt, nut and joint into a ring. Therefore, after the welding machine runs for a period of time, wipe the oxide layer on the surface with a fine emery cloth, and then tighten it. 3. The flash butt welding machine should avoid long-term short circuit of welding electrodes and welding parts to prevent burning the burner. 4. The workplace of t...

  • What are the main advantages of a butt welding machine

    What are the main advantages of a butt welding machine

    18 Aug 2022

    1. Energy saving. Radiator flash welding machine for two 125KVA resistance welding transformers for power, pneumatic compression, upsetting, no hydraulic station. Compared to other welding machines that use two 315KVA single-phase AC welding transformers and two 18KVA hydraulic station welders, the UN-250AB welder can save up to 78℅. 2. Low power grid requirements. It can only meet the grid of 250KVA. 3. High welding precision. Using programmable controller PLC and imported stepping motor to control the flashing process, the burning and burning speed can be set accurately; welding current is controlled by microcomputer welding controller. It can be controlled within ±0.2mm, which is convenient for subsequent welding parts. 4. Automatic centering function. Make sure that the two ends of the pipe are the same between the two ends to ensure the same amount of combustion at both ends. 5. High welding efficiency. With the time of workpiece pressure and force cylinder, the reaction speed is ...
