Fillet Welded Connection Joint Structural Solution For Industrial Civil Infrastructure

Product Description​
A Fillet Welded Connection Joint is a versatile and cost-effective structural joining solution that offers strong load transmission, good adaptability, and easy quality inspection. This product adopts the AWS D1.1 standard welding process, with a fillet weld cross-section in the shape of an isosceles right triangle, ensuring connection strength equal to the base material (Q235B/Q355B steel), suitable for lap joints, T-joints, and other common structural connections.​
One of the key features of this joint is its excellent construction adaptability—it can handle complex special-shaped components (e.g., irregular brackets, curved members) that are difficult for bolted connections to adapt to. Customers can choose from ER50-6 low-hydrogen welding wire, which effectively reduces the risk of welding cracks, while 100% ultrasonic flaw detection ensures weld quality, eliminating hidden safety hazards.​
For enhanced durability, the joint surface can be treated with shot blasting and anti-corrosion paint, adapting to outdoor, industrial, and other harsh environments. Its cost-effectiveness is another advantage: compared to high-strength bolted connections, it reduces material costs by 20% while maintaining equivalent load-bearing capacity, making it ideal for budget-sensitive projects.​
With its simple operation and mature process, the Fillet Welded Connection Joint is easy to promote on construction sites, requiring only certified welders to ensure quality. Whether it's for industrial workshop steel frames, bridge bearings, tower structures, or temporary construction supports, this product provides a reliable and economical joining solution.​
Customers can receive professional support including welding process design, on-site quality inspection guidance, and weld defect repair advice. The technical team is committed to ensuring that each weld meets the design requirements, helping customers balance cost and structural safety.

Applications​
Fillet Welded Connection Joints are versatile and economical joining solutions widely used in industrial, civil, and infrastructure projects. Certified by AWS D1.1 and GB/T 12470, they meet international welding quality standards, ensuring reliable performance in various scenarios.​
These joints are suitable for a broad range of applications, including industrial workshop steel frames, bridge bearings and brackets, tower structure connections, temporary construction supports, and agricultural facility steel structures. Their adaptability to special-shaped components makes them particularly useful for non-standard structural designs, such as custom-made machine frames and irregular building facades.​
The minimum order quantity is flexible (no fixed minimum, based on project needs), and weld size (leg length 6-20mm) can be customized to match different load requirements, making them suitable for both small-scale repairs and large-scale construction projects. Competitive pricing and low material costs (20% lower than bolted connections) make them a cost-effective choice for budget-conscious customers.​
Delivery time depends on project scale, with standard small-batch orders (≤50 joints) delivered within 3-5 workdays. The manufacturer offers flexible on-site welding services, ensuring that joints are completed in line with project schedules. With a service life of over 40 years and customizable anti-corrosion treatment, these joints adapt to environments from indoor workshops to outdoor bridges and coastal structures.​
Customization options include weld size adjustment, anti-corrosion coating type (epoxy, polyurethane), and welding process optimization for low-temperature or high-humidity construction environments. Whether it's for standard or special-shaped connections, the Fillet Welded Connection Joint delivers reliable performance at an economical cost.
