Typical application scenarios
• Precision welding: such as automotive parts, mechanical structural parts, pipeline welding, etc.
• Fixture positioning: used for precise positioning during assembly and inspection.
• Small - batch and multi - variety production: Rapid change - over to reduce the cost of special fixtures.
• Education/R & D: Suitable for scenarios that require flexible adjustment, such as training and prototype making.
Applicable industries
• Automotive manufacturing (body welding, chassis part positioning)
• Aerospace (precision structural part welding)
• Machining (fixture manufacturing)
• Steel structures (bridge and building component welding)
• Maintenance and prototype development (quick adjustment to adapt to different workpieces)

Core Features
(1) 3D Flexible Design
• Three - dimensional adjustability: The surface, sides of the workbench and the fixtures can be adjusted in the X, Y, and Z directions to meet complex welding requirements.
• Modular hole system: A standard hole array of D16 (16mm), which is compatible with various positioning pins, fixtures, and support parts.
(2) Portable Structure
• Compared with large fixed welding platforms, this model has a moderate size (1000×1500mm), can be moved or disassembled, and is suitable for flexible use in the workshop.
• Some models are equipped with adjustable feet or rollers, which are convenient for adjusting the level or moving.
(3) High - strength Cast Iron Tabletop
• Anti - deformation: Cast iron has good shock absorption, reduces welding thermal deformation, and ensures long - term accuracy.
• Wear - resistant and corrosion - resistant: The surface is usually quenched or rust - proof treated to extend the service life.
(4) Modular Fixture System
• Standard or optional quick - acting fixtures, angle adjustment blocks, V - shaped positioning blocks, etc. are available to achieve rapid workpiece clamping.
• Suitable for various welding requirements of pipes, plates, special - shaped parts, etc.
Commonly matched accessories
• Locating pins (D16 standard, various lengths available)
• Quick clamps (manual/pneumatic available)
• Angle adjustment blocks (15°/30°/45°/90°, etc.)
• V-shaped support seats (used for positioning pipes/cylindrical parts)
• Extended worktops (optional for a larger working area)
