Product Introduction:
To address the industry pain points of carbon steel clamps and hoop clamps being prone to deformation during welding, unattractive weld spots, and heavy spatter, this dual-head capacitor-discharge projection welding dedicated machine has been launched. The resistance weldert adopts capacitor-discharge technology, which delivers highly concentrated heat and effectively protects thin-walled ring parts from thermal deformation, producing flat weld spots with almost no spatter. Left and right dual vibratory bowl feeders automatically feed the small buckle/latch parts, so the operator only needs to manually load the rings. The two independent welding heads on the left and right press down in sequence to perform projection welding, while a pneumatic-hydraulic booster cylinder provides stable pressure. This not only eliminates the cumbersome manual alignment required in traditional processes but also ensures the weld strength and consistency of every clamp product, helping companies easily achieve semi-automated, high-quality production.
Features:
1.Single clamping, dual-end forming: The operator only needs to place the ring into the fixture once, and the machine automatically completes welding of the buckles on both the left and right sides. Compared with traditional single-head welding machines that require flipping or realignment, efficiency is increased by 100%.
2.Fully automatic small-part feeding: The left and right vibratory bowl feeders continuously feed automatically, so workers do not need to pause during welding to pick up small buckles, enabling a minimalist streamlined workflow of “load ring – press start – remove part.”
3.Extremely short welding cycle: The capacitor-discharge power supply discharges in milliseconds, and combined with the rapid press-down and lift of the pneumatic-hydraulic booster cylinder, the welding cycle for a single clamp is extremely short, perfectly matching the production takt of high-volume assembly lines.
4.Extremely low operator threshold: The semi-automatic operation mode places very low skill requirements on workers, and no experienced welder is needed. Ordinary general workers can take up the post after simple training, greatly alleviating the factory’s “recruitment difficulties.”
5.High yield rate reduces rework: Stable pressure and energy output ensure a very low scrap rate, reducing rework time caused by cold joints and burn-through, thereby invisibly greatly improving overall production capacity.
Welding Test:


Welding Workpiece: Engineered specifically for tabbed steel clamp rings, this dual-head capacitor discharge projection welding machine broadly accommodates various ring-shaped hardware components including pipe hoops, exhaust clamps, hose clamps, pipe clamps, tab clamps, metal fastening rings, and U-clamps. Through its step-by-step welding process for carbon steel, galvanized steel, and stainless steel parts with custom stamping tabs, it perfectly solves the common thin-walled ring welding pain points of thermal deformation and excessive spatter, making it highly suitable for mass production across the hardware fasteners, automotive parts, home appliance assemblies, and pipeline engineering industries.
Detailed Images:

Dual Independent Welding Heads & Electrodes: Say goodbye to workpiece deviation caused by single-head welding. Step-by-step pressing ensures uniform force, while high-conductivity copper electrodes guarantee perfectly consistent welds at both ends.

Gas-Liquid Booster Cylinder: Completely prevent cold and missed welds. The gas-liquid booster outputs multiple times the thrust, pressing instantly without bouncing, ensuring every projection weld is rock solid.

Dual Vibratory Bowl Feeders & Feeding Mechanism: Bid farewell to inefficient manual picking of small parts. Dual vibratory feeders automatically sort and deliver materials precisely, allowing operators to focus solely on loading/unloading the main parts easily and efficiently.

Energy storage welding control box: Eliminate thermal deformation and annealing discoloration. Large-capacity capacitors discharge in milliseconds with highly concentrated heat and minimal spatter, saving you post-weld grinding.
