1.Introduction for Space frame welding machine:
The main body of the Automatic Space Frame Welding Machine is assembled from high-quality steel metal components. All structural parts undergo annealing heat treatment to relieve internal stress, ensuring excellent stability and long-term durability under continuous operation.
This automatic welding system features a swing welding function for the welding gun, with manual adjustment capability to accommodate different joint configurations and welding requirements.
The primary and auxiliary clamping devices are hydraulically operated, providing reliable and consistent workpiece holding power. After welding is completed, the machine automatically releases the workpiece. Lifting of the workpiece is achieved via a manual lead screw mechanism, offering simple and controlled handling.

Characteristics and Performance
The Automatic Space Frame Welding Machine is designed for high-efficiency automated welding of truss structures. Its standout feature is the ability to weld both sides of the workpiece simultaneously, effectively doubling production output compared to single-side welding systems. This dual-side welding capability significantly improves overall efficiency and ensures balanced weld quality on both ends.
The machine delivers reliable weld quality that meets China's flaw detection standards (Class I/II level). With imported PLC control, the system offers high precision, stable performance, and low maintenance costs. Operation is exceptionally user-friendly—even operators without prior welding experience can become proficient after a short training period.
Welding Diameter Range
The machine accommodates rod workpieces with diameters ranging from 42 mm to 180 mm. Standard body length is 7.2 meters, with customized lengths available upon request to suit specific production requirements.
Standard Configuration
Each standard unit includes:
Main welding machine body with dual-side welding heads
Imported PLC control system
Hydraulic primary and auxiliary clamping devices
Manual lead screw lifting mechanism
Two CO₂/MAG welding power sources (brand can be specified by the client or selected by our company based on quality and availability)
Working Process
The typical working sequence is as follows:
Workpiece Loading – The rod is positioned and secured using the hydraulic clamping system.
Welding – Both welding guns operate simultaneously on both sides of the workpiece, with swing welding function and manual gun adjustment for optimal joint coverage.
Workpiece Release – Upon completion of the weld, the hydraulic clamping system automatically releases the workpiece.
Lifting and Unloading – The finished workpiece is lifted via the manual lead screw mechanism for safe removal.
Productivity Data
Ф48 mm workpiece – Welding cycle: approximately 20 seconds per piece; one spool of welding wire can produce up to 1,000 pieces.
Daily output (per worker):
Ф48 mm: 600–800 pieces/day
Ф76 mm: 400–600 pieces/day (using 1.5 bottles of mixed gas)

products faq
A standard welding machine is a single power source that requires manual operation and external positioning equipment. An Automatic Welding Center, by contrast, is an integrated system that combines welding power source, wire feeder, manipulator, positioner, and PLC control into one coordinated unit. It automates the entire welding process—including torch movement, workpiece rotation, and parameter adjustment—delivering higher consistency, faster throughput, and reduced operator dependence.
Depending on the configuration, an Automatic Welding Center can support multiple processes including GMAW (MIG/MAG), GTAW (TIG), submerged arc welding (SAW), and RMD (regulated metal deposition) for root pass welding. Some advanced designs integrate up to three welding methods on a single manipulator, switchable by rotating the boom 180°, offering exceptional flexibility for diverse applications.
The system is designed primarily for cylindrical and rotational components, including pressure vessels, boiler shells, pipelines, wind tower sections, and hydraulic cylinders. It is suitable for both longitudinal seam welding and circumferential seam welding. With modular positioning accessories such as roller frames, positioners, and lifting supports, it can adapt to a wide range of diameters, lengths, and material thicknesses.
Quality is maintained through several integrated features: PLC-based parameter control ensures repeatable welding conditions; laser seam tracking (on advanced models) maintains torch alignment within ±1% tolerance; frequency converters provide stepless speed regulation for smooth motion; and real-time monitoring systems halt welding immediately if any subsystem anomaly is detected, preventing defects before they occur.
Yes. The system features user-friendly interface panels and remote control boxes for flexible operation. Setup involves basic parameter entry for the specific weld job—such as speed, current, voltage, and travel distance—after which the center executes the programmed sequence automatically. Batch program storage allows quick changeovers for mixed-product manufacturing. Operator training is typically straightforward and supported by comprehensive documentation.
Routine maintenance includes inspecting welding cables, torch consumables, and grounding connections; checking lubrication of moving parts (manipulator arms, roller drives, and linear guides); and monitoring the cooling system and wire feeder condition. The PLC and frequency drive systems are generally maintenance-free but should be kept free of dust and moisture. We recommend regular inspection schedules based on operating hours, with full technical support and spare parts available from our service team.
