Step-by-Step Process

1. Safety First

Always wear safety goggles, gloves, and ear protection. Metal grinding can produce sparks and loud noise, so taking precautions is essential.

2. Initial Grinding

Use an angle grinder with a 40-grit flap disc to begin removing the bulk of the weld seam. Hold the grinder at a slight angle to the tube, applying even pressure along the seam.

3. Fine Grinding

Switch to a 60-grit flap disc for more refined grinding. This step helps to smooth out the surface and further reduce any unevenness.

4. Detailed Filing

For precise work, use a metal file set to address any hard-to-reach spots. Work slowly to maintain control and avoid creating deep scratches.

5. Polishing

Finally, switch to an 80-grit flap disc to polish the area smoothly. For a high gloss finish, apply a metal polish using a soft cloth.
