6 FAQs about [Medium frequency energy storage welding]

What is the power supply for resistance welding machine?

The power supply for resistance welding machine could be alternating current, direct current, or pulse current. Alternating current frequency is divided into four types: low frequency (3–10 Hz), power frequency (50/60 Hz), medium frequency (150–8000 Hz), and high frequency (10–500 kHz).

What is a good frequency to weld a stainless steel sheet?

Acceptable results are reached with a frequency of 4000 Hz and an amplitude of 0,05 mm. With these parameters, the feed rate could be increased to 800 mm/s at both 300 and 400 W and a full penetration of the weld is achieved. This is a requirement in the welding of thin stainless steel sheets, since it reduces warpage.

What is resistance welding machine & testing equipment?

The development of resistance welding machines specifically for welding requirements of coated materials, aluminum alloy materials, and precision parts welding have become more prominent. The development of testing technology and testing equipment will promote the improvement of process and technical levels of enterprises.

What are the components of a welding machine?

Main components of the equipment: The whole machine includes: welding host (body), flexible welding cylinder, AC welding power supply and control system, upper and lower electrode parts, water cooling system, safety mechanism, etc.

What are the advantages of resistance welding?

The advantages of resistance welding are the formation of plastic connection or molten core surrounded by plastic ring connection. It has simple metallurgical process, short heating time, heat concentration, small heat-affected zone, small stress and deformation, and high welding quality.

What are the different types of resistance welding?

Resistance welding (spot welding) According to welding methods, resistance welding can be divided into four kinds: spot welding, projection welding, seam welding, and butt welding (Fig. 2). (1) Spot welding. The workpiece is overlapped between the upper and lower electrodes and pressed tightly.
