PTA Welding Machine
(Plasma Transferred Arc)& System
PTA welding machine (Plasma transferred arc welding machine) is a thermal process for applying wear- and corrosion-resistant layers on surfaces of metallic materials.
WALDUN are expert on production and sales of PTA welding machine. WALDUN PTA welding machines have higher quality with moderate price. If you have budget to purchase one, don’t hesitate to contact us.
PTA Welding is a versatile method of depositing high-quality metallurgically fused deposits on relatively low-cost surfaces.
The PTA process is used in instances of extreme demands on wear resistance.
Plasma transferred arc welding machine is mainly used in high quality large flat surface spray welding.
After surface hardness can reach HRC58-60, within the scope of the 1000 x1000 weld layer does not crack, not obvious deformation.
Can work out a complete plane without defects, can be used in the manufacture of rolling mill bearing high hardness skateboard.
PTA Welding Machine Feature:
- High automation, one button start and stop, simple operation, greatly simplifies the operation process
- Barreled welding wire located above the beam, to ensure smooth wire feeding
- Water cooling effect is good; ensure welding wear-resistant plate, plate deformation after welding is very small
- CNC systemis used to control the operation of the machine, AC variable frequency speed regulation, improve equipment reliability
- IPC control the stability of the platform, in order to ensure the long time stable operation of welding system
- Machine parameters can be set to make any combination of the welding torch welding
- The integration of multi welding torch swing, driven by AC servo motor, stable swinging, weld forming beautiful
- Breakpoint welding function
- Air-cooled torch improve consumable life
