D28 U Shaped Square Box for 3D Welding Table
Why Do You Need This "U-Shaped Box"?
• ❌ Nightmare of traditional fixtures: Pipes tend to roll under force, with spot welding positioning deviations exceeding 1mm, requiring repeated correction.
• ❌ Efficiency black hole: Building a complex support structure for special-shaped parts takes 20 minutes, while welding only takes 5 minutes.
• ❌ Interference curse: Ordinary right-angle blocks are too high for welding torches to reach, resulting in missing welds and cold welds.
👉 If you are tired of wasting time on "correction" and "rework", this U-shaped square box is your lifesaver.
Products Details
This is not an ordinary cast iron block. It is a high-precision, multi-functional, fully relieved welding positioning tool.
• Core design: U-shaped open structure provides 5-sided machining/welding space, allowing the welding torch to move around the workpiece without collision.
• Locking method: Compatible with D28 locking pins and quick clamps (to be used together).
• Material and craftsmanship: High-strength cast iron/carbon steel (to be filled in according to your actual material), not easy to deform and resistant to spark splashes.
Products Parameters
Products Application
Application Scenarios
• Pipe truss welding: Positioning of round pipes after intersecting line cutting.
• Frame/roll cage fabrication: Ensuring parallelism of round pipes.
• Repair of special-shaped parts: Firmly "clamping" irregular workpieces.
• Square pipe frame: Rapid assembly and welding of 90-degree right-angle frames without the need for try squares.
FAQ
Q1: What diameter of round tubes is this suitable for?
A: The U-shaped groove design is highly versatile, typically suitable for round tubes with a diameter of 15mm - 50mm and corresponding square tubes. Please refer to the dimension drawing above for details.
Q2: Can it be directly locked onto my D28 workbench?
A: Absolutely. It is equipped with standard D28 positioning holes at the bottom and can be fixed on a 3D welding table using locking pins.
Q3: Is it resistant to impact? Will it deform?
A: Made of high-precision cast iron/steel and heat-treated, it will not deform even under long-term knocking.
