Brand new About this product
The Ledger Welding Machine by National Cutting Tools is an automated production workstation engineered for circumferential fillet welding of cast or forged steel end blades onto tubular scaffolding ledgers. In modular scaffolding systems like Cuplock, Kwikstage, and Ringlock, ledgers act as horizontal ties; weld integrity at the blade-to-pipe junction is vital to resist tensile pull-out and bending moments during service. The machine uses a heavy horizontal steel bed with a motorized rotary headstock and an adjustable tailstock carriage. Pneumatic jaws clamp the cut-to-length 48.3 mm OD tube while precision locator fixtures hold the end blades in true axial alignment. Dual welding torches initiate simultaneously, laying down clean, spatter-free circular welds around both ends in a single automated cycle taking under 40 seconds. Key Features Simultaneous Dual-End Welding: Two independent MIG torches weld both end connectors simultaneously, balancing heat input and cutting cycle time by half. Interchangeable Blade Tooling: Drop-in locator jaws accommodate forged Cuplock ledger blades, Ringlock cast wedge heads, and Kwikstage captive wedges. Adjustable Length Carriage: Smooth-sliding tailstock assembly on machined ways accommodates ledger lengths from 0.4 m up to 2.5 m with positive mechanical stops. Rotary Inverter Drive: Variable frequency drive allows smooth speed control from 2 to 12 RPM to match pipe wall thickness and wire diameter. Pneumatic Clamping Sequence: Foot-switch activated pneumatic cylinders clamp the pipe and lock end fittings in place before arc initiation. Spatter Protection Guards: Heavy acrylic and sheet metal sliding hood protects the operator from glare and contains welding fumes and spatter. Applications Fabrication of Cuplock forged-blade horizontal ledgers Ringlock cast-head ledger and transom welding Kwikstage horizontal ledger and tie bar production Circular tube-to-fitting welding in structural steel workshops Manufactured at the NCT engineering works in Ludhiana, Punjab. Every machine is tested for spindle alignment, weld bead uniformity, and pneumatic clamping force before being packed for delivery across India or for overseas container export.
