Tube inside Scarfing Inserts

During high-frequency welding of steel tubes, excess weld material often forms along the inner seam, creating internal burrs that can interfere with downstream processes or product quality. The inner burr removal knife is a critical tool designed to trim and smooth these internal weld protrusions in-line during tube production, especially for applications requiring high inner surface quality—such as in automotive tubing, furniture, and fluid transport systems.

Inner Burr Removal Knife for ERW Tube Mills

During high-frequency welding of steel tubes, excess weld material often forms along the inner seam, creating internal burrs that can interfere with downstream processes or product quality. The inner burr removal knife is a critical tool designed to trim and smooth these internal weld protrusions in-line during tube production, especially for applications requiring high inner surface quality—such as in automotive tubing, furniture, and fluid transport systems.

Working Principle

The inner burr knife is typically installed after the welding section and before sizing. A precision-guided support mechanism feeds the knife head into the inner diameter of the tube, aligning it directly under the weld seam. As the tube continuously moves forward, the knife scrapes or shaves off the burr along the weld line. Some knife heads feature oscillating or rotary action to enhance trimming efficiency. Removed burr particles are discharged and collected via an external extraction system.

Key Specifications (customizable upon request)

  • Applicable Tube Diameter: Φ16 – Φ219 mm (larger sizes available)

  • Wall Thickness Range: 1.0 mm – 8.0 mm

  • Knife Material Options: Carbide steel, HSS (High-Speed Steel), Ceramic-coated

  • Knife Mounting System: Mechanical locking / Spring preload / Pneumatic-assisted

  • Cooling Options: Air-cooled / Water-cooled / Dry-cutting (depending on application)

 

Common Questions & Answers

Q1: Is burr removal always necessary?
Not always. For light-wall or general-purpose tubing, internal deburring may not be required. However, it's recommended for structural or high-spec applications.

Q2: How long does the knife last?
The knife is a consumable. HSS or carbide blades typically last 1–3 weeks depending on speed, material, and maintenance. Keep spare sets available for continuous operation.

Q3: Does the knife require precise weld alignment?
Yes. Poorly aligned or inconsistent welds can cause blade deflection or breakage. Weld quality should be stable before applying internal burr removal.

Q4: Is the knife easy to replace?
Yes. Most knife holders are designed for quick change, with replacement typically taking just a few minutes.

 

Usage Tips

  • Always align the knife precisely with the weld seam before operation.

  • For automated lines, use seam-tracking systems to optimize blade positioning.

  • If scratching or tube wall damage occurs, inspect blade sharpness and angle settings.

  • When changing tube diameters, use matching knife heads or inserts for best results.
