I believe this topic is far enough from my other post that it warrants a new thread.
I would like to know what the general consensus is for sandblasting plain old steel materials before TIG welding it, vs just grinding or sanding the material?
Sandblasting is probably more work but it would remove very little material and have a very clean uniform surface for welding. However sandblasting may or may not leave behind dust or particles that we dont want in our welds, same could be said when using abrasives to remove surface rust.
Generally we`d use new materials that are coated in grease or whatever that black stuff is [mild steel] but since i`m practicing i`m using junk steel plate that I had left over from old projects.
