Q: What is a Shear Welder? How Does It Work?

•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

Mechanical Execution System:

•Control Layer:​

The PLC and control modules inside the electrical cabinet manage logic and

instructions. The operation panel features a Human-Machine Interface (HMI)

and buttons for parameter setting and status monitoring.

•Execution Layer:​

Components such as the welding torch stepping motor, proximity switches, and

pneumatic/hydraulic solenoid valves execute actions based on PLC commands

(shearing, clamping, aligning, and welding).

•Operation Modes:​

Supports both manual step-by-step operation and fully automatic welding

cycles, enabling seamless automation from feeding and shearing to alignment

and welding.

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:​
