Why does the energy storage spot welder not store energy after discharging

What are the advantages of spot welding apparatus?

Main advantages the spot welding apparatus: high performance; minimum heat affected zone due to high energy density and short pulse; connection strength; simplicity of technology that does not require highly qualified personnel; uniformity of the mains load at high welding currents. Let's consider the operation of the welding device in more detail.

What is the discharge for welding process?

The discharge for the welding process gives a block of ten electrolytic capacitors with a voltage of 35 V and a capacity of 10,000 mF. This method allowed to reduce the size and increase the safety of the device. The discharge Copyright © 2020 for this paper by its authors.

What causes welding defects?

Welding defects can be caused by the presence of areas of local anomalous overheating of the alloy and can be asso-ciated with the formation of discontinuities in the process of plastic deformation , which requires further research. Fig. 1. Discharge energy of the capacitors of the spot welding apparatus. The inset shows the welding process.

What is an adjustable spot welding apparatus?

An adjustable spot welding apparatus , developed by a team of authors, belongs to the type of semiautomatic devices and is implemented in a capacitor method without using a transformer . The discharge for the welding process gives a block of ten electrolytic capacitors with a voltage of 35 V and a capacity of 10,000 mF.

Why should you choose an adjustable spot welder?

The cheapness of the development. According to the results of the calculations, an adjustable spot welder costs an average of 29% cheaper compared to analogues . Ergonomics and ease of use . The device is quite easy to disassemble, and bend the corrugated body of the electrodes in the required direction to perform difficult-to- access work;

Can welding current pulses be single and combined?

Welding current pulses, during which heating and welding of products are carried out, can be single and combined. To improve the quality of welding, the device has the ability to form combined pulses, consisting of two or more parts following each other.
