In high-volume manufacturing, welding efficiency is often limited by manual positioning and inconsistent setup times. This welding jig is developed to streamline the production process by enabling quick part loading, precise positioning, and stable clamping in a single operation.

Improving Throughput in Link Rod Welding Operations
By reducing setup time and minimizing operator intervention, it significantly increases throughput while maintaining consistent welding quality. The fixture is especially suitable for production lines where cycle time and repeatability are critical performance indicators.

FAQ
What materials are your welding fixtures suitable for?
Our fixtures are mainly designed for carbon steel, alloy steel, and automotive structural parts such as connecting rods, compatible with most gas-shielded welding processes.
What is the positioning accuracy of your welding fixtures?
Our standard positioning accuracy is ≤ ±0.03 mm, ensuring stable part dimensions and consistent welding quality.
Do you support custom fixture design?
Yes, we provide full custom design based on your product drawings, welding process, production beat, and equipment layout.
What welding processes are compatible with your fixtures?
They support GMAW (MAG / CO₂ welding), assembly welding, tack welding, and continuous fillet welding.
How long is the fixture production and delivery time?
Standard fixtures: 20–35 days; Custom fixtures: 35–50 days (depending on design complexity).
What materials are used for the fixture body and key parts?
The base uses stress-relieved heavy steel plate; key pins and clamps use S50C, 40Cr or hardened alloy steel for high wear resistance.
Is operation difficult? Do you provide training?
Our fixtures feature one-time positioning & quick clamping, easy to operate. We offer online guidance, operation manuals, and on-site training support.
How about the service life and maintenance?
Designed for ≥1,000,000 clamping cycles. Wear parts are replaceable, and routine maintenance is simple and low-cost.
