Gantry-type Multi-axis Welding Machine
Juyoubao provides customized gantry-type multi-axis welding machines for automated welding of large, long, heavy and structurally complex metal workpieces.
Unlike a fixed welding robot with a limited working radius, a gantry welding system allows the welding unit to travel across an extended working area. Multiple linear, rotary and positioning axes can be coordinated to reach weld seams located at different heights, angles and positions.
Our gantry-type multi-axis welding machines can be configured with MIG/MAG welding, pulse welding or laser welding systems according to the customer’s material, workpiece dimensions, weld joint, production volume and required weld quality.
The complete solution can include the gantry structure, welding robot, external axes, workpiece positioner, welding power source, customized fixtures, control system, safety protection and welding process development.
A gantry-type multi-axis welding machine is an automated welding system in which the welding head or robot is mounted on an elevated bridge structure.
The gantry provides one or more linear travel axes, allowing the welding unit to move along the length, width or height of the workpiece. Additional robot, rotary or workpiece-positioning axes can be integrated to create a coordinated multi-axis welding system.
This structure is particularly useful when:
The number of axes, gantry travel, robot reach and positioner capacity can be customized according to the actual workpiece.
The gantry structure extends the movement range of the welding unit beyond the reach of a stationary industrial robot.
It can be designed to cover long workpieces, large frames, multiple fixtures or several production stations. The travel length, working width and gantry height can be adjusted according to the customer’s factory layout and product dimensions.
Linear gantry axes, robot axes and workpiece positioners can be integrated into one control system.
Coordinated movement enables the welding torch to maintain a suitable angle and travel speed while the workpiece is rotated or repositioned. This helps reduce manual handling and makes weld seams on different surfaces more accessible.
Large structural components are often difficult to move repeatedly during production. A gantry system moves the welding unit around or above the workpiece, reducing the need to reposition heavy components.
Customized heavy-duty fixtures, rotary positioners and support platforms can be added according to the workpiece weight and center of gravity.
The rigid gantry structure and controlled linear movement are suitable for continuous longitudinal welds, frame welds and other extended welding paths.
The final welding stability depends on the gantry rigidity, transmission system, welding process, fixture accuracy and workpiece consistency.
The system can be configured for different welding processes, including:
The welding source, torch, wire feeder, shielding gas and process parameters are selected according to the material and weld joint.
Juyoubao currently provides three gantry-type multi-axis machine configurations. Buyers should select the model according to the workpiece weight, welding process, material and production requirements rather than relying only on the machine name.
| Model | Recommended Application | Main Selection Consideration |
|---|---|---|
| YB-QS-350(280) Heavy-Payload System | Large, heavy or difficult-to-position metal components | Workpiece weight, payload, gantry travel and fixture capacity |
| YB-QS-DD-350(280) Multi-Material Industrial Welding Robot | Factories welding different metal materials or multiple product types | Material range, welding process, changeover frequency and weld quality |
| YB-QS-DS-350(280) Automotive Laser Welding Robot | Automotive components and applications requiring laser welding | Laser power, penetration, seam tolerance, cycle time and laser safety |
This configuration is recommended when the project involves large or heavy metal components that are difficult to move manually.
The gantry travel, robot payload, fixture capacity and workpiece positioner should be selected according to:
Before production, Juyoubao can evaluate the workpiece drawing and recommend a suitable gantry range, payload and fixture layout.
This configuration is suitable for manufacturers producing different metal products on the same welding line.
The welding package can be selected according to the material grade, coating, thickness and weld-joint requirements. Program storage and interchangeable fixtures can also be considered when several product models share the same machine.
Customers should provide sample materials or workpieces for welding trials when weld appearance, penetration, porosity or spatter requirements are critical.
This configuration is designed for applications requiring laser welding speed, narrow heat-affected zones or controlled deformation.
A complete laser welding solution may include:
Laser power and welding speed should be selected according to the material, thickness, joint gap and required penetration.
Suitable for beams, columns, support frames, brackets, platforms and other fabricated steel components containing long or repetitive weld seams.
The machine can be customized for agricultural equipment frames, brackets, supports, chassis components and other large welded assemblies.
Suitable for structural frames, machine bases, lifting components and heavy-duty fabricated parts requiring multi-position welding.
Applicable to automotive frames, brackets, structural assemblies and other components requiring repeatable automated welding.
Laser welding configurations can also be developed for suitable automotive applications.
The gantry system can weld large furniture frames, shelving systems, storage racks, bed frames and tubular structures distributed across a wide working area.
Suitable for trailer frames, carts, material-handling equipment and other long or multi-section structures.
The system can also be customized for pressure-free tanks, industrial frames, enclosures, platforms and other large fabricated metal products.
| Selection Factor | Gantry-Type Multi-Axis Welding Machine | Fixed Welding Robot |
| Working range | Can be extended along customized linear axes | Limited mainly by the robot’s arm reach |
| Workpiece size | Better suited to large, long or multi-section components | More suitable for workpieces within a fixed robot cell |
| Multiple stations | Can travel between several fixtures or work areas | Usually assigned to one fixed working area |
| Floor layout | Requires space for the gantry and travel path | Usually has a more compact cell layout |
| System customization | Travel, height, width and external axes can be customized | Mainly customized through robot selection and positioners |
| Typical use | Large structures, long seams and heavy components | Small and medium-sized repetitive components |
| Investment | Depends heavily on travel, payload and integration | Usually lower for a standard single-robot cell |
A gantry system is recommended when the required welding area exceeds the effective reach of a stationary robot or when one welding unit must cover several fixtures.
A fixed 6-axis or 8-axis welding machine may be more economical when the workpiece is relatively compact and all weld seams can be reached within one workstation.
Juyoubao provides more than an individual welding robot or gantry frame. We develop complete automated welding solutions around the customer’s workpiece and production process.
Our project services can include:
The working range is customized according to the workpiece dimensions and factory layout. Please provide the required longitudinal travel, working width and welding height for technical evaluation.
