Welding Tips and Tricks

Anyone use an Evolution 380 to cut welds? Do you need a different blade?

I don't have a band saw, my alternatives are a regular 14" abrasion disk chop saw and cut off disks on an angle grinder.

I'm interested in cutting and etching.

You need the correct blade for the material, steel, aluminum or stainless. See HERE

Sorry I forgot to say welds on mild steel.

Yea you can use the EVO 380, just make sure you have the blade for mild steel. You also need "rolocs", or something similar to do the polishing steps. I use

• 2" flap disc 40grit to remove the saw/blade lines first (go 90° to the lines as best as possible will work fastest)
• then maroon sanding pad to remove the 40grit lines (again, go 90° to the previous scratches to work fastest)
• then finally the blue sanding pad (again, 90° to the lines left from the maroon pad).

Then I dab Naval Jelly rust remover with a Q-tip and gently swirl it around for about 45 to 60 seconds, and I can already start to see the weld "nugget" start to appear. If you leave it too long, it etches everything too much, and turns it all dark-gray, then you can't see what's what.
