lookin for actual constructive critisism here from anyone who is qualified.






same weld diff pictures. thx.

 

i'm not qualified but that is one sexy weld.

 

What kind of material is it?

 

Looks like a collector on a turbo manifold.

Nice welds....much better that I can do. Only thing is it looks like they might be a little bit undercut. Kinda hard to tell from that angle

 

i'm not qualified due to the fact i've only spot welded , but i know a good amount about welding, and have seen amazing welding thanks to my old boss, and that, is a very nice weld

dude u work at full-race .. y would u ask if thoes are good ?
u know there good and i bet so does everyone at full-race ..

i kinda think u posted that just to brag. and have people tell u how good u are

excilent welding .. just lighten up on your ego

 

The Welding Inspector in me says it appears to be 100% acceptable.

The Welder in me wonders why there's 3-4 ripples, then a dark line...and repeating. It looks as if you welded a few dabs of wire, then stopped to get another grab on your wire...possibly even long enough that your postflow turned off. Although this not a problem, it's an area that you could improve. Presuming I'm right about you getting a new grab on the wire, you would really be helping yourself out to learn to feed the wire without stopping.

It doesn't look like you were pumping the pedal, but it is possible...if you are, I'd stop that practice ASAP.

Overall though...the weld looks nice. I've seen "professional" welders that have been doing it for 20 years that can't put down a bead like that.

i know theyre good. i wasnt looking for people to applaud me.
and if i was posting it to brag, i would have put up alot more pictures. why dont you take your ego expertice over to the fi forum and say the same **** to everyone who posts their cool new setup or ooo look what i got in the mail. i was looking for critisism on the weld, not my ego, but thanks.

thanks! your wrong about the wire thing though, i can feed forever like that so thats not a problem. my cup is small...im not sure. so i only go so far so i dont burn the weld. i know that spot is being coverd in gas, but it makes that dark spot anyway...any idea?

and why is pumping the pedal bad?

another question....what is "walking the cup?" ive never had any formal training in welding and have no idea about alot of things but ive heard you use that phrase before im not sure what it means though.

 

those are beautiful welds

 

Walking the cup is hard to explain. The only way i can start to explain is youd move the cup along the desired path with it never leaving the surface of metal. You could do it on the small pipe but it would be very hard to do since the pipe you are working with is such a small diameter. I dont think you could do it on the collector to, I assume you just use the groove or dip were the two collector pipe meet as your guide to keep the torch steady, thats what i have done in the past.


Walking the cup results in welds looking like a snakes skin, not like 1/2 moons or figure 8's. I used to work at a pipe fabrication shop(steam boiler pipes) and all the SS they did they always Heli-Arc'd and they old journeyman who always worked with SS "walked the cup". Pumping or "pulsing" the pedal i assume is what your doing but at the same time your heat signature looks pretty consistent so idk.

Do you guys at Full-Race purge you mani's w/Ar when you weld them? Also do you do all the welding at Full-Race?


p.s. You should post some close ups like this on the runner welds... i'd like to see how steady your hand is (can never tell how steady peoples hands are on the collector welds)

 

It is a nice weld but I'd be more interested in how the inside looked.

I know. I want to know if the "GODS" at Full-Race purge (just poking a lil fun)

 

so walking the cup is it just sitting on the metal, so your hand doesnt shake or whatnot? never done that. i dont understand what you mean when you say it looks like snakeskin.

yes its purged, no i dont do all the welding.

the inside is welded also.

ill get some runner pics up sometime

 

still trying to get my welds to look half as good as that. Still trying to get my purge system set up. After that I think my welds will be mucho better.

IF thats a problem...boy Id take that any day. :D

it doesnt look like cirlces. as i said its very hard to explain on text...here



Resulting in this (this is not as good as it could be)

 

damn jackson....why u gotta use my machine

 

thats a beautiful weld

It looks to me like your torch purge runs out while you wait for the weld to cool. That, or youre JUST missing the affected heat "puddle" if you will, while youre waiting for it to cool.
&lt;--I too have had no formal training, but this is what I notice with my welding.
A good example of your guys' "dark rings" are shown really well with these welds:

Ive notice when I pump the pedal, ESPECIALLY on head/turbo flanges, that micro-cracks occur if you let the metal cool down too quickly. This might be what Engloid is getting at/why its bad.

I just had my pipe test last week and to fill the 1/8 gap with a root weld i used "walking the cup". i wish i coulda kept the pipe and posted pictures. The weld looks almost robotic

 

so walking the cup is a cross stitch weld resting the cup on the metal?

my gas isnt running out at all, and like i said before i know for a fact that the area is being sheilded from the atmosphere by argon.

 

looks good... but im in no way certified or whatnot... id like to see the inside as well... i would question the dark rings as well and i have no clue as to how they be (if i hadnt read this thread)

walkin the cup... hmmm... good for gaps (which suck... but sometimes i gotta deal)

i thought i seen something some where you guys used a hydrogen mix for your gas ?????

yes sir. Now you understand the "snakeskin"?

I've never tig welded, but I am certified in structual steel welding and this type of weld would fail due to the fact that its caused by not waiting for the puddle to catch up. Creating snakeskin/fish scales/etc. Altho structual steel isn't manifolds and tig isn't stick, so who take it as you will.

But as far as the first welds go, the bead doesn't mean jack if the penetration isn't there. But at least it looks pretty right?

Well this went into a BFGoodrich tire plant and its a 12inch dia SS sch10 pipe. It's not structural so that has nothing to do with it. Its made to hold heat and pressure. Also there is no "catching up" that the puddle has to do. You add filler in front of the torch when usign this procedure. Stick and TIG are 2 separate beasts. And i do both every week at work.


This is purely the cosmetic pass to cover the penetrating and sealing root pass, but you knew that right?
