Nirmal Overseas is the leading manufacturer of Solid State Welder which is used for the
welding process. In solid state welder, two workpieces are joined under a pressure providing an intimate contact between them
and at a temperature essentially below the melting point of the material. Eventually, it is used to weld the material or joint
the two edges of tubes and pipes.
Solid state high frequency welding pipe equipment's uses the common structure of frequency
conversion such as AC-DC-AC. Three phase 380V power supply is sent to step down transformer before it passes through switch
cabinet. The AC power supply is around 200V which has been dropped voltage to sent into the rectifier in rectifier cabinet,
Rectifier use threes phase thyristor fully controlled bridge rectifier, through control thyristor break-over time delay angle
A to achieve the purpose for adjustment output power size.
The rectified DC voltage is sent to the high frequency inverter
before pass through the filter link. High frequency inverter to inverter producing single phase high frequency and being sends
to resonance circuit via the matching of load and the adjusting mechanism output high frequency energy to complete steel pipe
welding.
The comparison with vacuum tube high frequency, the main difference between vacuum tube welder is its efficiency
SSW efficiency is 85% as compare to vacuum tube welder which is 65% and SSW no oscillator valve is used solid state welder save
electricity consumption because off its 25% efficiency saving.
Welding pipe power supply Vacuum tube high frequency
welding pipe equipment has accumulated operation design experience for a long-term, the equipment quality and the operation
stability have been accepted by the general welding pipe enterprises. Along with the promoted application of solid state welded
pipe equipment, its strong advantage for highly effective energy conservation opened a new path for the intense welded pipe
profession competition. The third generation solid state high frequency power supply has many fine performances, there is no
doubt it has the competitive advantage compares our company earlier period the second generation solid state high frequency
power supply.
