On the precise track of modern industrial Welding, the MFDC
Spot Welding Machine has become the performance benchmark in the Spot welding Machine field, thanks to the precise current control brought by the medium-frequency inverter technology. In collaboration with other welding equipment, it has redefined the quality standards for metal point connection with its efficient and stable spot welding capabilities.
Compared with the
Friction Welding Machine's welding method that relies on frictional heat generation, the MFDC spot welding machine uses the concentrated heat generated by medium-frequency direct current to form a uniform weld core at the contact points of the workpieces. It is particularly suitable for welding difficult-to-weld materials such as high-strength steel plates and aluminum alloys. It can effectively avoid the deformation problems that may occur in the connection of thin plate points by friction welding. The
Butt Welding Machine focuses on the overall butt welding of workpieces, while the MFDC spot welding machine is good at performing scattered high-strength point connections on large components. For example, in the welding of automotive body frames, its millismillisecond current regulation accuracy can ensure the consistency of strength at each weld point, significantly enhancing the safety of the vehicle body structure.
In the manufacturing process of household appliance shells, it is closely coordinated with the
Seam Welding Machine: The seam welding machine is responsible for the sealing welds of the shell to ensure the water resistance of the product, while the MFDC spot welding machine handles the point fixation between the shell and the internal bracket. Its low spatter welding process can reduce the subsequent grinding process and improve production efficiency. for precision parts of Steel rings, the
Laser Welding Machine for steel rings is renowned for its high precision. However, in the multi-point fixation of steel rings and metal plates, the MFDC spot welding machine, with its faster welding speed and lower equipment cost, is more adaptable to the demands of large-scale mass production.
When it is necessary to fix small studs on metal components, the
Stud Welding Machine completes the initial welding of the studs, while the MFDC spot welding machine performs reinforcing spot welding at the connection points between the studs and the base material. Together, they enhance the load-bearing capacity of the connection structure.
Whether it is the precise Spot Welding of battery casings for new energy vehicles or the connection of metal frames for high-end furniture, the MFDC Spot Welding Machine occupies a core position in the field of spot welding with the precise control, efficient operation and stable quality brought by medium-frequency DC technology. At the same time, it works in coordination with other types of welding machines. Provide complete welding solutions from point to surface for industrial manufacturing.
Feature:
Medium frequency inversion constant current welding power source is mainly made up of transformer, controller, inverter, power drive,rectifier parts, capacitor plates, IGBT as well as the central control components. Medium frequency inversion constant current welding power source is a set of advanced welding equipment and is widely used. The size of welding transformer is small but the output of energy is large. The feature is the original input voltage 50/60HZ cn be rectified to 1000HZ and the rectified diode of transformer secondary circuit can transform the power into constant current power source so that the secondary circuit reactance coefficients can be greatly improved (it is an important factor in causing the loss of energy before improvement), and it is almost taken into consideration in constant current welding circuit, almost, and thus production costs are minimized. Compared with conventional welding power source, it has the following
advantages:
*Save Electricity
*Improve the power factor and reduce production costs In the secondary circuit with large opening area,interference can be reduced and welding current is constant current. When the secondary winding has inductive materials (with magnetic property), it will not affect the welding
*Make a balance of the loading of power supply device ,medium frequency inversion constant current welding power source uses three-phase power and stores energy
*The adaptability to the fluctuation in the grid and the pressure drop is strengthened. Some are stored by dc-to-ac inverter to supply loading and replace the way of supplying power and loading form the grid
*More accurate, rapid and accurate analysis to parame-ters
*Damage of oblique wave interference caused by SCR systems can be avoided
