Welding machine. What does the pulse do:

Pulse welding machine is used for welding FPC, PCB, LED display, wire, terminal.

and other products. The YLPC-1A heat press uses pulse heating technology to work, so the temperature control is very accurate. As a result, heat presses are often used in places with very strict temperature requirements.

When the hot press machine is working, it can use multi-stage heating to effectively control the machine. The temperature of the hot press can be expressed by the real-time temperature curve, which is simple and easy to understand, which greatly facilitates the work of the operator.

Pulsed TIG welding.

It is an argon arc welding method that uses the base current to maintain the electric channel of the main arc, and periodically adds a copolar high peak pulse current to generate a pulsed arc, so as to melt the metal and control the transition of molten droplets. Among them, the use of tungsten electrode is called tungsten pulse TIG welding, and the use of welding wire as an electrode is called fusion pole pulse TIG welding.

The characteristics of pulsed TIG welding are:

1.The pulse heating makes the high temperature residence time of the melt pool short and the condensation is fast.

2.Due to the reduction of welding heat input, both the heat affected zone and the welding deformation are reduced, which is conducive to the welding of thin plates.

3.Precise control of heat input and weld pool size facilitates single-sided welding, double-sided forming, and full-position welding of tubes.

4.The oscillation of the high-frequency arc has the effect of refining the grains. And the stiffness is large, and the directivity is strong, which is conducive to high-speed welding. Hope, thank you, thank you!

Advantages: good arc striking performance, good adaptability of welding parameters to the welded workpiece, heat input can be kept to a minimum, coarser wire can weld thinner workpiece, less spatter in the whole pulse power adjustment area, good porosity resistance of the weld, the melting efficiency of the space weld is about 25% higher than that of DC welding, good corrosion resistance; Disadvantages: welding equipment is more expensive, welding equipment is more complex to adjust, contact tip life is shorter.

Spot welding machine single pulse and hall which trillion double pulse are common welding equipment, and they are used in industrial production to achieve resistance welding. Their differences and functions are as follows:

1.Single Pulse Spot Welding Machine:

Difference: The single-pulse spot welding machine only produces one current pulse at a time.

Function: Single pulse spot welding machine is suitable for general welding tasks, such as for fast welding of thin plates, welding of small parts, etc. They are relatively low in energy and cost-effectiveness, simple to operate, and suitable for simpler welding applications.

2.Double Pulse Spot Welding Machine:

Difference: The double pulse spot welding machine will produce two current pulses of different intensities during the welding process, which are called the initial pulse and the post-pulse.

Purpose: Double pulse spot welding machine has higher welding quality and a wider range of applications. They are suitable for heavier welding tasks such as welding thick plates, complex structural parts, etc.

The initial pulse is used to heat the solder joints and material surface, and the post-pulse is used to increase the weld pressure and strength to achieve a stronger weld lease result. The double pulse spot welding machine can provide higher welding quality and strength, and ensure the stability of the welding joint.

Overall, single-pulse spot welders are suitable for general welding needs, while double-pulse spot welders are suitable for more complex or tasks that require higher welding quality. Which type of spot welder to choose depends on the specific welding needs and the type of material.

If you want to change the pulse parameters, you need to re-excite and set a new setting after the shutdown.

2. The general output parameters of the double pulse power supply are fixed, and if you want to change the pulse parameters, you need to reset the anodizing dissolution of the reverse pulse of the double pulse power supply after the shutdown, so that the metal ion concentration on the surface of the cathode rises rapidly. This facilitates the use of high pulse current densities for the subsequent cathode cycle, resulting in a dense, bright coating with low porosity; The anodic stripping of the reverse pulse of the double-pulse power supply greatly reduces the entrapment of organic impurities (including brighteners) in the coating, so that the coating has high purity and strong resistance to discoloration.

Pulse hot pressure welding machine is a kind of equipment that uses pulse current and thermal pressure to weld metal materials together. The principle is that through the instantaneous heating of electric current and the action of pressure, the metal material is plastically deformed on the contact surface, so as to achieve welding.

The working principle of the pulse hot pressing welding machine mainly includes the following steps:

1.Current heating: First, an electric current is transmitted to the electrodes of the welding head via a power supply. When an electric current passes through the electrode, it creates an impedance, which generates heat. This heat is mainly concentrated on the contact surface of the weld head, causing it to heat up quickly.

2.Plastic deformation: When the contact surface of the welded head reaches a certain temperature, the metal material begins to undergo plastic deformation. At this time, the pressure of the welding head causes a plastic flow of the limb bright metal material, so that the metal particles on the contact surface combine with each other.

3.Cooling and curing: When the metal material is plastically deformed, the heating is stopped and a certain pressure is maintained. In this process, the metal material gradually cools and solidifies, resulting in a strong welded joint.

The principle of pulse hot pressure welding machine mainly relies on the heating of electric current and the action of pressure, and the lead tan can realize the welding of different materials by controlling the heating time, heating temperature and pressure and other parameters. Compared with traditional welding methods, pulse hot pressing welding machine has the advantages of fast welding speed, high welding quality and low energy consumption, and is widely used in automobile manufacturing, aerospace, electronic equipment and other fields.

1. The pulse power heating method is a way to use the Joule heating generated when the pulse current flows through high-resistance materials such as molybdenum and titanium to heat the welding sail. Generally, a hot couple is connected to the front end of the heating nozzle, and the generated power is fed back to the control power supply in real time to ensure the correctness of the set temperature.

2. The pulse current heating device is an instantaneous heating method, which only carries out through-based hail electric heating when the solder needs to be melted.

3. The metal welding nozzle heats up when an electric current passes through.

After melting the solder. After the solder is melted, the power is stopped and cooled. When the solder is solidified, it is possible to obtain high-reliability soldering without false soldering or floating.

4.Pulse heating welding is a method of heating welding by using the heat generated when a pulsed current flows through a high-resistance material. Generally, the temperature control system with a hot couple is connected at the front end of the heating head for real-time circular feedback of the hot ferrule, so as to achieve the temperature of the hot ferrule consistent with the set temperature parameters; The pulsed current heating device is an instantaneous heating method that heats up the solder only when it is necessary to melt it.

Multi-stage temperature can be set according to different conditions of soldering to meet the needs of different soldering process parameters, and the setting is flexible; At the same time, it is equipped with an air blowing function, which can realize the demand for rapid cooling, and it is easier to solve the problem of poor welding such as virtual welding and poor welding; Moreover, it adopts pulse instantaneous temperature heating control technology, which is more energy-saving and environmentally friendly.

The current is constant when the TIG welding machine without pulse is welding, and the current is controllable during the welding process, and the current size has pulse changes, so the heat input is small and the welding deformation is small.

The pulse heat press is different from the constant temperature soldering iron, the pulse heat press can reach the desired temperature at the moment of power-on, and once the voltage is not applied at both ends of the welding head, the room temperature can be reached in an instant; Moreover, the welding head is flat, so the appearance of welding is smooth and consistent, and there are very few virtual welding defects.
