Re: Grinding metal for painting


Not to scale, but here is how I welded plate butt joints. MIG or stick.

Re: Grinding metal for painting


I took it to my current welder. He might have been the previous welder also as I don't remember who welded it 20 years ago. He said at 1/4" even if butted up against each other the weld done right would penetrate 1/8" per side so full penetration and a good weld if I wanted to grind the weld off.

When this garage extension is done maybe it is time to take up welding, now that I will have the space.

Well if you are going to learn to weld, learn to TIG and you wont need to grind it.


This is from the handrail inside my house. Welded on all sides with a small amount of filler rod. For something structural I would have added more filler but it would have looked just as nice.

Nice work rrmcabe,
I wish I could do that so I could build my own railing for my upcoming balcony.

Is TIG appropriate for stainless steel? My hobbies include sailing and brewing, both require using stainless steel so would like to learn how to work with it someday.

Absolutely. my uncle built his own sailboat and I welded a lot of the stainless parts like the mounts for the railing and most the mast parts, anchor chain rollers, etc.


And almost all brewery and food stuff is TIGd. I used to be the plant engineer at a potato chip factory and that is where I learned how to do it.
