Introduction
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.
Technical characteristics of high-frequency pipe welding machine
First, more convenient installation
Second, the floor area is small
Three, simplify the circuit, reduce the failure rate
Four, improve the safety factor
Five, more convenient maintenance

Power supply cabinet
The DC power unit includes rectification, filtering and logic
control parts.
Independent voltage and current display and control system -
independent control of the welder even in the event of a problem
with the central console.
Center Console
Equipped with LCD screen, power adjustment, motor speed adjustment
module, fully realize the centralized control of welded pipe
production line.
Inverter cabinet
The inverter part consists of a single MOSFET inverter unit in
parallel, and each unit has a self-diagnostic capability for easy
installation and maintenance.
Water heat exchanger
Composition: plate heat exchanger, water tank, water pump and
electrical control part
Rectifier Isolation Transformer
The rectifying transformer is the input rectifying part of the
equipment. The power supply voltage is reduced from 415V to 200V,
which ensures the stable power supply of the equipment and plays
the role of isolation to the power grid.
ZTZG Company Introduction
FAQ
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.
