Removing TIG welds on flat stainless steel
You remove a TIG weld on a flat stainless steel workpiece with an abrasive that removes material fast, stays cool and doesn’t damage the surface structure. With the wrong choice, you get overheating, discolouration and an uneven result.
Which product suits your workpiece
For the fastest removal, choose the LKGR or the AF890 fibre disc. Looking for an affordable solution? Then there is the LZGR.
LKGR
Ideal for removing a TIG weld quickly and coolly.
- Compact grain, from grit 80 to 1400
- Long-lasting
AF890
Ideal for maximum removal on the angle grinder.
- Ceramic grain
- Less heat in the workpiece
- Extra long service life
LZGR
Affordable choice for removing a TIG weld.
- Zirconia grain
- Less aggressive than the LKGR
Choose the right back-up pad
Depending on the machine you use and the workpiece, choose from:

How to remove a TIG weld on a flat stainless steel workpiece in 3 steps
Choose your disc and back-up pad
Choose the LKGR or AF890 for the fastest removal, or the LZGR as the affordable choice. Mount the disc on the right back-up pad for your machine.
Grind away the weld
Work with even pressure and keep moving. This keeps the workpiece cool and prevents discolouration.
Check the result
Check that the weld is flush with the surface everywhere. Then finish further if needed.
Frequently asked questions about removing TIG welds on flat stainless steel
What is the best way to remove a TIG weld on a flat stainless steel workpiece?
Use an abrasive that removes material fast and stays cool. The LKGR grip disc on a back-up pad for angle grinders is our choice: it removes TIG welds quickly, stays cool and lasts a long time. Work at a flat angle and with light pressure.
Do you choose a fibre disc or a grip disc for TIG welds on stainless steel?
Both work. The AF890 fibre disc in grit 80 gives maximum stock removal with less heat build-up and an extra long service life. A grip disc such as the LKGR is quicker to change and is used with a hook-and-loop back-up pad.
Is there a more affordable disc for removing TIG welds on stainless steel?
Yes, the LZGR with zirconia grain is our economical choice. It is slightly less aggressive than the LKGR, but still suitable for removing weld seams on stainless steel.
Which back-up pad do you use for removing stainless steel weld seams?
For grip discs, use the VELVZ. Its extra strong, heat-resistant hook-and-loop holds the disc in place, even during intensive use. For fibre discs, choose a fibre disc back-up pad such as the FIH, FIW or FIZ.
How do you prevent discolouration when removing a TIG weld on stainless steel?
Don’t grind in one spot and work with light pressure, so the heat doesn’t build up. A sharp, cool-grinding disc also helps: the faster you remove the weld, the less heat enters the workpiece.
