Are the electrodes of the energy storage welder an important component?

The electrode of Suzhou Anjia energy storage welding machine is an important component to ensure the quality of soldering mask, and it should have the functions of conducting welding current, pressure, and heat dissipation to the workpiece. The electrode raw material should have high electrical conductivity, thermal conductivity and high temperature hardness. The structure of the electrode must have sufficient strength, stiffness, and sufficient cooling conditions.

Because the touch area of the electrode determines the current density, and the resistivity and thermal conductivity of the electrode data are related to the generation and loss of heat, the shape and data of the electrode have a significant impact on the composition of the nugget. With the deformation and wear of the electrode head, the touch area increases, and the strength of the solder joint will decrease, which is particularly important for the protection of the electrode head.

The electrode of the energy storage welding machine is a very important component, and its quality determines whether the welding quality of the weldment is qualified, but the electrode is also a wearing part, which needs to be resharpened or replaced regularly.

Hello pro is very happy for you: after the energy storage welding machine completes the welding work, the possible reasons why sparks will still appear when the upper electrode is released are as follows:1

Electric energy is still stored in the energy storage capacitor: The welding process of the energy storage welding machine is to store the electrical energy in the capacitor and release the electric energy when a certain amount of electric energy is reached. If the energy in the capacitor is not fully discharged after soldering, there will be residual electricity and sparks when the upper electrode is released.

2.There is an induced current between the electrode and the workpiece: In welding, a closed frontal loop is formed between the electrode and the workpiece, which creates an induced current in the loop.

Even after the soldering is completed, these induced currents remain until the capacitor is discharged. 3.The electrode surface is not cleaned

Too many contaminants accumulate on the surface of the electrode, such as grease and iron oxide, which will lead to poor contact between the electrode and the workpiece, which will cause partial discharge and sparks. To sum up, if there are sparks in the energy storage welder after welding, it is necessary to check whether the capacitor is completely discharged, exclude the influence of induced current, and keep the electrode surface clean and smooth. Hope it can help you dear.

Hello, energy storage welder.

There are several main factors that affect the use of electrodes: one is the material of the weldment, if it is the stainless steel of Pubi Raid, etc., the electrode.

The damage will be very serious, but if it is made of aluminum, it will cause great damage to the electrode and need to be regular.

Regrinding. Or replace the electrodes. Also, the angle of the electrode will also affect its use.

The electrode of the welding workpiece of Suzhou Anjia energy storage welding machine is a very important part of the dust, because the wear of the electrode is too fast, or the planning is not reasonable, which will affect the production power. The following is an introduction to the factors that affect the performance of the electrode:

1.The diameter of the electrode contact surface is generally determined by the thickness of the workpiece. The electrode garden cone angle can be selected according to the workpiece structure. From the perspective of the life of the electrode, the larger the cone angle, the better the heat dissipation, and the less easy the electrode is to be compacted and deformed. Generally, about 105 degrees is more appropriate.

The interval from the bottom of the electrode cooling water hole to the end face of the electrode head has a great relationship with the application performance of the electrode. Because the smaller the interval, the better the electrode cooling, the more collapsed the welded joints per unit length of wear, and the smaller the electrode adhesion. However, this interval is too small, and the lifetime of the electrode decreases in general.

If the interval is too long, when the electrode is first used, the electrode wears and the number of solder joints per unit length of welding is small, and the tendency to stick to the electrode is large. Generally, the interval from the bottom of the electrode cooling water hole to the end face of the electrode head is 10 15mm, which is more suitable. When the electrode is worn to 2 3mm, although the number of welding joints per unit length of electrode wear is large, the hardening phenomenon simply occurs for metal materials with a large quenching tendency.

3.The interval from the end of the water core to the bottom of the electrode cooling water hole. The interval from the end of the water core to the cooling water hole of the electrode has a great relationship with the service life of the electrode.

If the interval is too short, the cooling water will not flow smoothly and the electrode will not cool well. In the process of application, the electrode is easy to heat, easy to press, aggravate the wear, and the phenomenon of sticking to the electrode is serious, which will also reduce the life of the electrode, and the welding quality is difficult to guarantee. However, it is too long, because the water at the bottom does not flow, and "dead water" will appear at the bottom of the electrode cooling water hole.

Therefore, this part of the water will be vaporized and the cooling water will be blocked because the temperature continues to rise during welding. In this way, the electrode is not cooled well, which affects the welding quality and reduces the service life of the electrode. Generally, the interval between the water core and the lower part of the electrode is:

6~8mm。

4.The shape of the working surface of the spot welding electrode is determined by the shape of the workpiece and the properties of the material. The shape of the commonly used electrode working surface can be selected according to the specific situation. The various electrodes we use are specified in the process card and cannot be easily changed.

Hello, there are several factors that affect the use of electrodes in energy storage welding machines: one is the material of the weldment, if it is ordinary stainless steel, etc., the damage to the electrode will not be very serious, but if it is made of aluminum, it will hurt the electrode very much, and the electrode needs to be resharpened or replaced regularly. Also, the angle of the electrode will also affect its use.

Energy storage welding is a welding technology that stores the charge in a capacitor of a certain capacity, so that the welding torch is discharged by the welding consumables and the workpiece at a high frequency pulse of 2-3 times per second, so that the welding consumables and the workpiece can achieve metallurgical combination at the instantaneous contact point.

At present, the most widely used energy storage welding machine in the industry has many characteristics:

1. The controller adopts a single-chip microcomputer control system, which is simple to operate and maintain, and the control specification is accurate and stable;

2. Combination of software and hardware, synchronous control, to ensure welding quality and high precision;

3. The capacitor voltage can be adjusted arbitrarily from 35 to 400V with an accuracy of 1V;

4. The circuit is charged and discharged rapidly, the welding current is stable, and the charging and discharging frequency is high;

5. Digital display panel, simple operation and exquisite appearance;

6. There is a button sound to remind the operator of the successful operation and prevent incorrect operation.

Will choose a mechanical equipment, it must be because of the role of the mechanical equipment itself, it is very good, such as its function, or effect, but also to reduce some processing costs, these are very critical, but also people want to buy, energy storage welding machine is the same, so why do we choose Anjia energy storage welding machine reason?

Current control. The welding current is pulsating DC, and there is no disadvantage that AC zero crossing does not heat the workpiece. The frequency of each welding is milliseconds, and the output current is automatically detected every millisecond to ensure the consistency of the output current, avoid the influence of power grid fluctuations, and avoid the phenomenon of virtual welding.

The control accuracy is high, and the welding time can be controlled in the n cycle.

The energy storage welder releases the energy stored in the capacitor to the welding circuit at one time, and the output energy regulation is done by controlling the charging energy of the capacitor. There are generally two ways to adjust the charging voltage and capacitor capacity. The output current is a pulse current, and time cannot pass.

Electronically controlled adjustments. The current control is relatively poor.

Long-term stability. There is no need to replace core components to ensure stability and consistency of long-term current output. Ensure consistency in welding.

The core component, the capacitor, is a consumable product. It requires regular checking of the energy of the capacitor. Just like a rechargeable battery or laptop battery, after a period of time, it will also be fully charged, but the energy is not the same.

Capacitors need to be replaced.

Energy savings. The transformer of the inverter welding machine has a high operating frequency (1-4 kHz) and very small losses. The DC output improves the power factor, and the energy saving effect is obvious.

More than 50% of energy can be saved. The actual working frequency of the transformer of the capacitor energy storage welding machine is low, the core of the transformer is large, and the loss increases; Capacitor charging circuits also increase losses.

Device volume and weight.

The transformer of the inverter DC resistance spot welding machine is small in size, there is no large capacitor bank, and the equipment is lighter. The transformer core of the energy storage welding machine is large, the energy storage capacitor occupies a considerable space, and the equipment is bulky.

Energy storage welding machine, also known as capacitive energy storage welding machine, its working principle is mainly to use capacitor to store energy, when the energy can make a small area of solder joints melt, the capacitor is instantaneously discharged, the welding time of the energy storage welding machine is generally 3 thousandths of a second, and the welding time can not be adjusted.
