Q:What are is the Working Principle of Automatic Welding (Control System)?

•Manual methods require multiple operators to handle heavy lifting, shearing,

tack welding, and final welding—especially for wide and thick strips.

•With a shear welder, only one operator is needed to manage the process via

push-buttons or a touchscreen, significantly reducing physical workload.

(2) Lower Skill Dependency & Optimized Labor Structure

•Manual welding relies heavily on certified welders, who command high salaries

and are often difficult to recruit.

•Automation reduces reliance on specialized welding skills. General operators

can be trained quickly to run the machine, lowering operational costs and

increasing staffing flexibility.

(3) Superior & Consistent Weld Quality

•Manual welding often results in excessive weld reinforcement (beading) and

misalignment, requiring grinding to prevent damage to downstream rollers or

molds.

•Our machine employs TIG butt welding, producing flat, smooth seams with

minimal mismatch and reinforcement.

•Post-weld grinding is typically unnecessary. The strip passes smoothly

through subsequent processes, reducing the risk of strip breaks and improving

overall yield and equipment lifespan.

(4) Enhanced Production Efficiency

•When integrated with accumulators (loopers), the system facilitates non-stop

or minimal-stop coil changes, drastically reducing idle time.

•Digital parameter settings ensure high repeatability and precision, ideal for

to meet diverse production requirements:

•Strip Width Range: 30 – 1000 mm

•Thickness Range: 0.4 – 6 mm

•Applicable Materials:​Q195, Q235, Q355, and other conventional

low-carbon steels, mild alloy steels stainless steel, copper, aluminum, titanium

and other metals, which are suitable for arc butt-welding.

Specific models are available for different widths, thicknesses, and capacities.

Customization for non-standard requirements is also supported.

Secure the strips to prevent movement during welding.

•Alignment Device:​

Ensures precise edge alignment to minimize mismatch.

•Pneumatic/Hydraulic Shear Mechanism:​

Shears the strip ends cleanly and quickly.

•Welding System:​

Typically equipped with a TIG welding torch.

•Drive & Sensing Elements:​

Welding torch stepping motor, proximity switches and etc.

•Control System:​

Electrical cabinet (PLC, controllers), operation panel (HMI, buttons), and

various solenoid valves.

utilizing metal strips as raw material, including:

•Pipe Welding Lines (ERW)

•Cold Roll Forming Lines

•Continuous Stamping Lines

•Metal Processing Lines (Cold Rolling, Pickling, Annealing, Color Coating,

Galvanizing)

They handle the critical tasks of end shearing, alignment, and butt welding.
