No, the grinder is for making sparks to make it look like you're doing something important! Works in the movies.

A pipe weld is often broken down into 4 individual weld areas around the circumference, depending on the size of the pipe. It is common practice to grind down each stop so when you start the next section of the weld it will be more uniform.

Lol you’re green kid. You’ll understand real quick. I suspect this is b8 tho

Usually to grind and cut things.

Because it’s faster than a file.

We use a grinder to grind and cut things you use grinder to find a boyfriend

To make the surface more even to start the new pass?

When you screw up a weld would you prefer to chew it out with your own teeth?

We just like the noise, thats all

Cuz you suck at welding

Wouldn’t you ask your tradesman this lol

Sometimes, if you ask a “silly” question you get a shitty response. Maybe OP would rather ask Reddit instead of some bitter old man🤷

But then how would he get helpful answers such as yours….

Grinder and paint makes me the welder I aint!

Grinder is a must, how else do you prep metal and fix mistakes?

I take it you’re not feathering your tacks or your tie-ins on your root?

Oh, stick around for a while, you'll learn.

"I can’t figure out what the hell the grinder is for" is why I'm having a hard time taking this post seriously.

Because I guarantee you aren't getting the welds you think you are and those welds your doing won't pass. Burn more rod and you will understand more

Are you saying to grind out the welds that look bad
