Looking great Mike...awesome miters...your crown molding in the house must be spectacular!...:ylsmoke:
Technical noob question..when you miter steel like that, is it necessary to grind back the cuts in order to weld?
Keep the updates rolling in!
Thanks for the compliments and the question Titan!
To answer your question I would say yes and no.

With adjusting the welder settings I can easily get enough heat to be confident of the weld penetration with a tight butt joint like this. Now, having said that, for the welds that I know I will be grinding down I did take a thin cut off wheel in the angle grinder and open up the butt joint a little. This was really only for the welds on top of the frame where I will have the main box or other components sitting right on top of the frame. I didn't worry about opening up the outside corner vertical joints because the metal at that point is thin enough that it melts back pretty quick and then the filler metal from the MIG welding process adds it back in. I hope that all made sense. If not just let me know and I'll try again.
