Single Cantilever Type Welding Machine
Compact and Efficient Welding Solution for H-Beams and Structural Profiles
The Single Cantilever Type Welding Machine is a specialized welding system designed for submerged arc welding (SAW) or gas metal arc welding (GMAW/MIG) of H-beams, box beams, and other structural components. This machine features a cantilever arm structure, which holds the welding head and allows it to travel along the length of the workpiece with high stability and precision.
Unlike double-sided or gantry-type welding systems, the single cantilever configuration is compact and cost-effective, making it ideal for smaller workshops or production lines that require efficient, one-sided beam welding. The machine typically consists of a cantilever boom, motorized carriage, welding head, flux recovery system, and a control panel for adjusting welding parameters and travel speed.
It offers stable arc performance, deep weld penetration, and high deposition rates, particularly when used with the submerged arc welding process. The cantilever structure provides excellent accessibility for one-sided welds while maintaining a smaller machine footprint.
Key Features:
Cantilever design allows stable, precise welding from one side of the beam
Suitable for SAW or MIG welding processes, depending on application
Ideal for welding the fillet joints of H-beams, box columns, and frames
Motorized travel carriage ensures uniform movement along the beam length
Flux recovery system included for clean weld zones and cost savings
PLC or digital controller for easy operation and parameter adjustment
Space-saving structure suitable for medium to heavy fabrication workshops
Applications:
H-beam and box beam welding
Pre-engineered building (PEB) structures
Steel bridge and column fabrication
Heavy machinery and equipment frame welding
Shipbuilding and infrastructure steelwork
The Single Cantilever Type Welding Machine offers a reliable, economical, and space-efficient solution for structural steel fabrication. With its compact footprint and high welding performance, it is a preferred choice for manufacturers aiming to improve weld quality while optimizing production space.
