· I have 3/4" tubing which I need to remove the welding seam inside for a slide-fit project. The tolerance req. for this job isn't high, something like 0.1-0.5mm at min, or the tube must mount a hand-fit cylinder inside it so the protruding seam is just PITA and I need to get it off the easiest way.

Flash Removal. During manufacturing of steel pipe and tube, the electric resistance welding process extrudes a small amount of metal (weld flash) on both the inside (ID) and outside (OD) of the tube. The outside flash is always removed from the OD of the tube with a cutting tool which keeps the surface smooth and uniform.

In the case of longitudinal (axial) welding, the seam will have burrs, for example, on the inside which have to be removed. As the burrs are severed from the pipe by scraping, one produces a continuous, wire-like burr, which remains in the pipe. This wire-burr has to be removed from the tube. Such a removal is rather simple, if the pipe is a ...
