Welding Platform Case

Core application areas of 3D flexible welding platform

As a modular and rapidly reconfigurable tooling system, the 3D flexible welding platform has become an indispensable key equipment in modern welding production due to its high-precision positioning, flexible adaptation, and efficient operation characteristics. Its application scenarios cover a wide range of welding needs from small and medium-sized precision parts to large structural parts. The following are several typical application scenarios:

1. Automotive and parts manufacturing industry

In automobile production, the 3D flexible welding platform is the core equipment for welding key components such as body frames, chassis components, and engine mounts. Automotive parts are mostly produced in small and medium-sized batches with multiple varieties. The platform's modular fixtures (such as quick locking pins, adjustable support blocks, and angle locators) can be quickly reassembled through hole systems or T-slots to adapt to the size differences of parts in different vehicle models. For example, when welding the rear axle housing of a car, the platform can fix the workpiece through precise positioning holes and apply uniform pressure with pneumatic fixtures to avoid welding deformation; For thin-walled aluminum alloy components such as battery trays for new energy vehicles, the high precision of the platform (flatness ≤ 0.1mm/m) can ensure the consistency of welding seams and meet sealing requirements. In addition, the platform is often linked with robot welding systems to achieve automated processes from fixture switching to welding, adapting to the needs of "flexible production lines" in the automotive industry.

2. In the field of construction machinery and heavy equipment

The welding of construction machinery (such as excavator boom, crane boom, loader frame) is mainly based on large, thick walled steel structures, and requires extremely high welding strength and dimensional accuracy. The heavy-duty design of the 3D flexible welding platform (with a load-bearing capacity of several tons) and the large-area worktable (commonly 3m × 6m or customized larger specifications) can stably support giant workpieces. Its grid hole system (with a spacing of 50mm or 100mm) can quickly fix specialized support molds, ensuring that the workpiece does not shift during the welding process. For example, when welding the boom of an excavator, the platform clamps the workpiece from a three-dimensional direction through multiple sets of hydraulic fixtures, and controls the coaxiality of the key shaft holes within 0.2mm in conjunction with preset positioning benchmarks; At the same time, the anti deformation structure of the platform (such as thickened tabletop and reinforced rib design) can resist stress deformation caused by welding high temperature, ensuring the assembly accuracy of large structural components.

3. Aerospace and military manufacturing

Welding components in the aerospace field, such as aircraft landing gear connectors and rocket fuel tank flanges, often use high-strength alloys (titanium alloys, high-temperature alloys) and have the characteristics of "small batch, high precision, and high reliability". The micro level positioning capability (positioning accuracy ≤ 0.05mm) of the 3D flexible welding platform can meet the welding needs of such precision parts: through customized flexible fixtures (such as ceramic insulation support blocks, to avoid contact corrosion of dissimilar metals), precise clamping of complex curved workpieces can be achieved; Paired with a laser tracking system, the displacement of the workpiece during the welding process is monitored in real time to ensure that the deviation of the weld position does not exceed 0.1mm. In the military industry, the platform's rapid reassembly capability is also applicable to the multi variety welding of weapons and equipment (such as armored vehicle protective plates and missile launchers), shortening the changeover time and improving emergency production efficiency.

4. Welding of pressure vessels and pipelines

The welding of pressure vessels (such as chemical reaction vessels and gas storage tanks) and pressure pipelines must strictly follow the standards of sealing and pressure resistance. The standardized positioning system of the three-dimensional flexible welding platform can ensure the straightness and symmetry of the weld seam. For example, when welding large pipeline flanges, the platform fixes the two ends of the pipeline with a circular positioning disc and cooperates with a rotating worktable to achieve 360 ° continuous welding, avoiding positioning errors caused by manual flipping; For irregular pressure vessels, the adjustable angle support of the platform can adapt to cylinder sections with different curvatures, ensuring that the welding quality of longitudinal and circumferential seams meets ASME or GB 150 standards. In addition, the platform is compatible with various processes such as submerged arc welding and TIG welding, and can flexibly adjust the tooling configuration according to the container material (carbon steel, stainless steel).

5. Metal structural components and general mechanical processing

In the welding of general metal structures such as steel structure factories, bridge components, and machine tool beds, the flexibility of the three-dimensional flexible welding platform can significantly reduce tooling costs. Traditional welding relies on specialized molds, which require redesigning and manufacturing when changing shapes, while three-dimensional flexible platforms can complete the splicing and positioning of different specifications of steel (H-beams, angle steels, channel steels) through the combination of standardized modules (such as square rulers, V-blocks, and telescopic supports). For example, when welding steel structure frames, the hole system of the platform can quickly fix temporary supports, ensuring that the verticality and diagonal deviation of the frame are within 1mm/m; For small-scale non-standard mechanical parts such as gearbox housings and conveyor supports, the platform's rapid clamping capability (completing fixture switching within 30 minutes) can significantly shorten production preparation time and improve the economy of small-scale production.

In summary, the 3D flexible welding platform has achieved a dual improvement in welding efficiency and quality in fields such as automotive, heavy industry, aviation, and pressure vessels through its characteristics of "modular design+high-precision positioning+flexible adaptation". It is particularly suitable for welding scenarios involving multiple varieties, small to medium batches, or large complex structural components, and is the core supporting equipment for modern welding automation and flexible production.
