Product Description


Solid-state high-frequency welder can provide complete welding solutions for low carbon steel, high strength steel, copper, aluminum, stainless steel and other materials. High frequency power supply adopts AC - DC - AC frequency conversion structure. The design of the rectifier can be based on the different needs of the user's power network, using three phase 6 pulse thyristor rectifier, three phase 12 pulse thyristor rectifier or IGBT DC chopper and other forms.


Solid state high frequency welding machine application

Welding of low carbon and high strength steel pipe (round pipe, square pipe, rectangular pipe, special-shaped pipe), stainless steel pipe, copper pipe, aluminum pipe, H-beam steel, finned pipe. Welding methods can be divided into induction welding and contact welding.

Q: Are you a manufacturer?
A: Yes, we are a manufacturer. We have 4 factories ( Machining, Assembling, Heat treatment, and Moulding ). We also have our own R&D department. Welcome to visit us.
Q: What kind of payment term do you do?
A: We do T/T.
Q: What info do you need before giving me the price and proposal?
A: Since we design individual machines based on our customer's requirements, we need your desired products' basic dimensions, including all the pipe diameter(or tube length), thickness range, usage, raw material steel grade, coil weight, and degree of automation.
Q: What should I do if I just start a new business?
A: Contact us immediately, we provide a free consultant for pre-sales service. Also, we can help you solve the raw material (steel coil) purchase, worker training, international market price, and more.
Q: How do you do QA?
A: We have a special team to do strict QA, this is one of our strengths:
(1)Every gearbox will be tested for 8 hours with oil inside to guarantee there is no leak.

(2)Every shaft will be inspected for centering jumpiness.
(3)Every roller will be checked to make sure it's in the range of tolerance critical parts will be inspected for all dimensions.
Q: Why I should choose you? what are the differences between you and other Chinese suppliers?
A: We are concentrating on pipe-making machines for more than 20 years. We have constructed many steady trading partners in Asia, Africa, the middle east, Europe, and South America throughout the years. Our innovative designed production line and every single unit of the production line are economical and practical.
