JH-700 Four-Torch Gantry Wear Plate Hardfacing Machine
CNC gantry hardfacing system for automated wear plate production.
The JH-700 Four-Torch Gantry Wear Plate Hardfacing Machine is an automated overlay welding system developed by JINHUA for industrial production of hardfaced wear-resistant plates.
The machine uses a rigid gantry-type mechanical structure combined with four welding torches, multi-axis CNC motion control, servo-driven positioning, automatic welding path calculation, circulating water cooling and digital PLC control.
Four-Torch Gantry Platform Capabilities
The JH-700 combines a rigid gantry structure with CNC multi-axis motion, four-torch welding, automatic path calculation, active thermal control and integrated fume extraction.
What Is the JH-700 Gantry Hardfacing Machine?
The JH-700 is a CNC-controlled flat-plate hardfacing machine designed to deposit a wear-resistant alloy layer onto a steel base plate.
Unlike conventional welding carriages with relatively simple linear movement, the JH-700 uses a gantry structure with independently controlled motion axes, allowing the welding torches to move according to programmed welding paths.
During production, the system coordinates:
- Welding torch position
- X-axis travel
- Y-axis travel
- Z-axis height
- Wire feeding
- Welding speed
- Welding trajectory
- Torch cooling
- Base plate cooling
- Fume extraction
The PLC automatically calculates the required welding trajectory after the operator enters the plate dimensions and welding parameters. This provides a more automated and repeatable method for industrial wear plate production.
With a standard welding area of up to 1550 × 3200 mm, the JH-700 can be configured for the production of:
Hardfaced wear plates
Bimetallic wear plates
Chromium carbide overlay plates
CCO wear plates
Customized alloy overlay plates
The four-torch configuration, rigid gantry structure and programmable welding path system make the JH-700 suitable for manufacturers requiring stable batch production, high welding coverage and reduced dependence on manual hardfacing.
Gantry hardfacing platform — four torches, multi-axis CNC motion, water cooling and integrated fume extraction.
Four-torch parallel hardfacing — multiple torches operating across the plate surface to increase welding coverage.
Why Use a Gantry-Type Hardfacing Machine?
Stable structure for large flat-plate welding. The gantry structure is one of the main advantages of the JH-700.
Stable Structure for Large Flat-Plate Welding
The gantry structure is one of the main advantages of the JH-700. The machine consists of:
- Left and right gantry columns
- Upper connecting beam
- Welding carriage
- Vertical torch slides
- Horizontal adjustment slides
- Fixed worktable
- Cooling system
- Electrical control system
The gantry and worktable form a rigid frame structure. This design provides stable mechanical support for multi-torch welding and helps maintain consistent welding trajectories across large plate surfaces.
The main motion structure and welding feed structure are mechanically independent, allowing their positioning accuracy to be adjusted separately.
* Final machine positioning accuracy should be confirmed according to the actual machine inspection report.
Four-Torch Parallel Hardfacing
The JH-700 is equipped with four dedicated hardfacing welding torches. Multiple welding torches can operate across the plate surface to increase welding coverage and improve production efficiency.
Compared with single-torch hardfacing systems, the four-torch configuration is particularly suitable for factories producing wear plates continuously in medium- or high-volume production.
Actual production capacity depends on:
- Plate dimensions
- Base plate thickness
- Overlay thickness
- Welding wire diameter
- Welding current and voltage
- Travel speed
- Welding path
- Number of layers
- Alloy formulation
For new wear plate plants, JINHUA can recommend the machine configuration according to the required m²/day, plates/day or tons/month.
Four-torch gantry configuration — torches mounted on vertical slides along the upper beam.
Real-time welding trajectory display — programmed path, current position and process progress on the HMI.
JHM-650 Digital Hardfacing Welding Power Supply
The JH-700 can be configured with the JHM-650 digital hardfacing welding power source. The welding power system is designed specifically for overlay welding applications.
According to the standard configuration, the power source uses IGBT power components and flat-characteristic control technology developed for continuous hardfacing.
The power source is designed to provide:
- Stable welding output
- Continuous operating capability
- Strong arc stability
- High-current hardfacing capability
- Resistance to electrical interference
Final welding power configuration should be selected according to the welding wire diameter, alloy composition, deposition rate and required production capacity.
