•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.

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.
A:A shear welder is a specialized machine used in continuous metal strip
processing lines. Its primary function is to automatically shear the tail end of
the preceding coil and the head end of the succeeding coil, align them
precisely, and perform a butt weld. This ensures continuous production with
minimal downtime.
The machine utilizes Tungsten Inert Gas (TIG) welding.
•First, the hydraulic or pneumatic shearing mechanism shears off the
irregular ends of the strips.
•Next, clamping devices secure the two strips, bringing them into tight butt
alignment.
•Under the protection of inert gas (Argon), a tungsten electrode generates an
electric arc that melts the joint interface.
•The entire cross-section is welded simultaneously under pressure, forming a
strong, uniform seam.
