how to remove weld seam from square tube
1. Cutting method: This method uses a fixed blade or rotating cutting head inserted into the tube to cut burrs.
2. Rolling method: This method uses a rolling device inserted into the pipe to cause plastic deformation of the internal burrs, achieving the effect of thinning the height of the internal burrs.
3. Oxidation method: At the beginning of steel pipe welding, an oxygen flow is sprayed into the inner weld seam through a ventilation nozzle, and the residual heat of the weld seam is used to accelerate the oxidation of internal burrs, which fall off under the airflow.
4. Pulling method: When the steel pipe passes through the mold, the burrs inside the steel pipe are removed under the action of the circular blade of the floating plug.
