Anything welding

Can I get your guys opinion on this weld, not mine and I also don't recall where I found this picture but it intrigued me. It's the first time I've seen it done like this and to me it doesn't seem right...

 

Without really knowing just what that part is for and what it does.

Depends on who taught you and what type of work you do.

Looks like a wide weave that in most shops would get you one of those lectures if you don`t know what I mean your still young

Comes back to just how critical that joint is it might be just fine .

 

Looks nice, but it's a waste of time. Need more details to know for sure.

 

Looks to me like a link mount on a axle possibly, and yeah I've never seen a weld done like that and it looked to fancy.

That being said it is laid in there good and all, but I just wanted some clarification on to why I couldn't wrap my head around why someone would make a pass like that

 

It also looks like it was stitched and not a full weld, but the heat marks are pretty even so who knows

 

Not true. We downhill a bunch of heavy wall pipe. Just a matter of doing it right.

 

They walked the cup around some sort of flange. It's whatever.

 

My point was its easy to fuck up downhand. And im going to assume you are a pressure welder, so your welds are awesome. Most of us are not at that level.

 

Yeah no prob. Was just addressing this because it's not accurate

 

I used downhill all the time on thinner stuff less than 1/4". I was taught that with a thicker material, run it uphill. Aws d 1.1 or whatever its called.

 

Love benchmark flap disks. They seem to last a while longer than the expensive dewalt ones I get from tractor supply.

 

It's "easier" to run uphill and get a good quality weld than downhill.

You see downhill more with 31.1, 31.3 and 1104. And a lot of it is when a MFG of a product in a system or a client/company produces a wps specifying a downhill procedure, normally due to time or because it's considered "low pressure".


My comments on downhill are based off of many cert quals which are all ndt and dt via tensile, notch, side bend and face bend (and etch + xray). So opinion aside, the numbers in real world are comparable.

 

And throw name in for Norton discs

 

Are most of these downhill welds F3 xx10 type elecrodes? Just curious. Chatted with a pipline welder who said most of his work was 8010 downhill, root, fill and cap. I knew the root was downhill but was suprised to hear fill and cap was too.

 

Yup. 60xx,70xx, and so on. Then you get in to 5p, 5p++ and every other flavor.
Basically it's a light slag, cellulose rode ( makes gas.for shielding), with a very stiff arc. As you go up in the tensile strength (60,70,80) they get a bit more stubborn to manipulate and can almost be more ...spongy...? while looking at the puddle.

Theres a lot of generalities in welding that are applied poorly.
Ex. You can open root 7018. Columbia gas 12 on 12 branch tests

 

Being mostly self taught, this was a big thing for me. In the beginning I had some welds that were a little porous and that helped.

 

Cool, so many varieties of electrodes, thats what I like about stick.
I was taught with 6010 root, 7018 fill and cap. Its tricky to do haha! 2 of 10 passed their B pressure, I didnt feel like burning $350 to fail so I didnt try, need more experience.

 

Yup. That was 90% of my 31.1 stuff. Underground steam. Downhill root, hot pass, 7018 fill/cap

 

That's really dependent on the welding process being used

 

All my stuff was open root tig uphill. Tig was the only class i took before i decided i didnt want to be a welder. But I am doing it part time in an industrial maintenance shop while in school. We only use the er70s-6 mig wire there nothing special. I dont do much stick welding.
