beveling edges

[diverdale]

do you more experienced folks out there always bevel edges? I'm going to start on my cart using 1" square and want to know the general rule. I know in my stick class, we always beveled everything but that was for thick plate and big pipe.

What are you going to weld it with. John

I just bought a HH140 and a bottle of C25. Prolly use .035 wire.

I think John was asking what material you are going to be welding. Personally, if I need a full penetration weld and can't double side it, I'll bevel anything 1/8 and over. That's using the 140, C25 and .023.

FWIW too, you can dig deeper going FCAW over MIG, So if I were going to be building tank turrets, I'd go to the .035 FC, switch the polarity and no gas... I'd still bevel though.

sorry...yeah it's 1" square 16ga (.051?) I still have my old FC welder setup with .035 but wanted to play with my new mig unit. Are you guys recommending I use the flux core .035? I have .030 and .023 for the mig. Thanks again for all the help.

On 16ga, you don't need a bevel. Bbased on what you said you have, I'd run the .023 solid wire with the C25. Save the FC for when you really need it - that stuff is pricey.

.023 lives in my Lincoln but .030 will work too

Don't worry, you'll evaporate the 16g with the .023

Watch the joints as the ends of the Tube WILL evaporate- 16g is thin

Start on the Solid piece first and wash over to the Edge of the other piece.

OK, similar question. On 1 x 1 x 1/8" MS tubing, using C25 with an HH140, what wire should I go with? Size? Brand?

Based on the responses, I'd bevel for 1/8". Correct?

Thanks for these answers, guys. They really help.

Ain't that the truth... one second it's there, the next - it's a hole.

I use the .023 solid with the gas, but it really is a personal preference, .030 will work too as Ed said above. Brand again, is a personal preference, so far all I've ran is the Hobart brand the ER70S-6.

The bevel/not bevel question is really based on application. Do you need full penetration or not. Can you double side the weld or not? I've ran a lot of single side welds on non-beveled 1/8" where I didn't need full penetration. Just left a bit of a gap and got "good" penetration, but not full, but then I didn't need full.

So it's a question of application. If you were using 1/4" then yeah, bevel. But the 1/8" is more of a maybe, sometimes, depends, borderline, thickness.
