Two Heads Overlay Welding Machine| Hardfacing Equipment For Chromium Carbide Wear Plates

Two heads overlay welding machine is an ideal standard machine for production of chromium carbide wear plates. With the advantages of simple operation, low cost and long service life. Generally, one start up company shall have six two heads overlay machines, one leveling machine and one plasma cutting machine.

WALDUN is an expert on providing hardfacing welding machine. We have focused on the wear plates production for many years, so we can handle solutions for production of wear plates. Including welding, cutting, leveling and etc. You can rely on us and we will be your best partner in China.

Two heads hardfacing equipment

General Introduction

Two Heads Overlay Welding Machine is optimized based on the original structure, the main improvement is an update of the control system, it has a more humanized operation interface

The welding head made a number of improvements, making the machine running process more smoothly, totally enclosed rocking slider can guarantee the stability of the swing and maximum flow, to ensure the use within the cycle

Reasonable smoke dust removal system can effectively remove 90% of dust in production, to provide better working environment for operators

Equipped with the basis of the bottom beam for the customer from the trouble of pouring a concrete foundation, convenient installation, convenient for user to move the machine; also has new vitality and more high-end appearance!


  • 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
