Anything welding

I think someone mentioned that…. Glad you’re good to go!

 

I bought a used bumper off Craig's list for $100. It has some scratches and a little surface rust but is otherwise in great shape. The welds look fantastic accept for one of the recovery points which looks pretty bad.. What can I do to fix this?

I have a die grinder and angle grinder. Should I cut out the weld run a new bead?

 

Simple

Hit it with a wire wheel, and run another pass or two and call it done.

Cutting it off will also damage the bumper face, not to mention you don't show how it's welded on the backside.

Then you'll have to buy a new recovery point as you don't want to use that same one you're cutting out.

On top of putting a lot of heat by welding up an area that's already been welded before.

If that were my bumper, I'd run a full pass around to fill in all that undercut and possibly another to fuse wherever weld metal wasn't deposited (due to the recovery point overhanging).

 

I'm sure far shitter weld have gotten the job done.

 

Speaking from experience?

 

Someone in a welding group wanted one of my aquarium signs so, who am I to say no?







Really liking how this one came out.

I went 5% bigger not to mention I ran the feedrate at 5% faster.

 

Please include your cut rate/ PC output/iron thickness so those of us with tables can use those #'s as a baseline?

 

Don't have one, on the basis that I don't make signs to sell

The person just messaged me out of the blue saying he wants one so I just quoted a flat rate of $70 (and separate shipping)

It's 16 gauge, unpainted and 23.4" x 13.1"

I still make parts as my #1 item

Post yours seeing as how I have less experience here than anyone else regarding CNC

 

They swapped it out no questions asked

 

far from it..

 

I'll reiterate lol

Everyone here with a CNC plasma table (working) has far more experience than me

Until yours is 100% that is

 

They didn't say anything about other bottles being problematic?

 

Nope, the guy said it mustve been filled wrong

 

See that'd make more sense

 

I mix my own trimix for scuba and deal with the gas places. I don't even know what this statement means...

 

Just filled with straight argon, or trimix, or whatever other pressurized gas they deal with that doesnt do well with mig welding mild steel. One thing I can say is I'm glad it wasn't of the flammable variety.

 

Yup, sure am. Certainly can't say my early welds were flawless (nor could I say that about my current welds, cause I don't weld enough) but none of them have failed. Probably abused the early ugly welds much worse as I used to wheel a ton back then.

 

Yeah, that's true for anything really

Don't do it often enough, you don't build the muscle memory or anything for it

Not to mention learning that proper technique!

 

@Pyrotech

What all is left for your CNC table so it's running non-stop at 100%?

 

But they don't blend gasses to order. Most don't even fill anything. They take empty tanks and send them off and get truckloads of full tanks that are filled from banks at big facilities. If one tank has the wrong contents, there would probably be many more, and they would have a bigger problem on their hands. Helium is about $2 per cubic foot currently. A local dive shop got an empty T bottle exchange recently. Extremely expensive mistake.
