Been there!

We (production techs) are always wondering who and how our parts are being inspected before they leave the vendor. :roll:

Welded a bracket in to hang a Mac daddy hose real in our Extract Manufacturing Department... Nothing special but it turned out purdy.

After a 50% fail rate from that vendor in two orders (second order being a second chance after reporting the first), we switched vendors. The new one sends a He leak test report. However, they test to 1.0E-07 atm. cc/sec, and I test to 1.0E-10 (and can interpolate to about 5.0E-11). So far, no fails from the new vendor!

BTW, half of the "fails" failed a pressure and Snoop(tm) test, as well. Major fail in performance.

Steve,

At least they have scruples where you are. The vendor badgers our engineers to change the print and spec until they cave.

SMFH :roll: :x

To change a spec with my client requires an EMOC.

So changes don't happen often. I've caused two, by finding near-miss problems they never dreamt possible.

The excuse our "leadership" (I use that title VERY loosely) used when they caved was that we were in R&D phase. The parts and prints and specs have not changed since. Luckily, we (the production techs) have the experience and skill to make it right. (Most of us came from External Tank. Of those, all but two (myself included) have 25+ years in aerospace)).

All but two? Or "only two"? I ask because of where you inserted, "Myself included".

14 techs (of different skill sets) are from the previous program (External Tank). 2 of those (I am one of the 2) have less than 25+ years in aerospace assembly.

I am lucky to work with one of the welders who is a great mentor. He has experience of 30+ in welding of all types including pipe and structural.

RocketSurgeon,

I'm trying to decide if I like your avatar... At the size it appears on my screen it appears the fellow is wearing a beard and a turban, rather than a mask and scrub cap....

:shock:

There isn't a "what I welded the other day" thread, so figured I would post this here. Open corners on 1/4" flat stock. 226" worth. 220 Amps, 1/8" pure tungsten, 1/8" 5356 filler. 4 hours total, and that includes pressing the 'cupped', imported plate flat across it's face where it makes the short corners, so that I did not have any open inside corners. The welds are crowned slightly higher than the base metal in either direction. The tungsten starts well into the open corner and is rock'n rolled out for each bead to get that high build without getting overlap.

Image

At the end of that pipe to plate weld, a giant mosquito hawk decided to become part of it, so I had to 'cook' him out of it a bit. :D

Not my prettiest work, but the welds are sound. It was one of those, "while they wait" Friday deals.

Hey Tamjeff.....I gotta ask, what is that for? I have a project coming up, a custom beer trough for an outdoor bar and your piece looks alot like it. Do you charge by the inch for something like that? Sorry to pick your brain but I haven't come up with a price yet. Awesome welding as usual. I really like that mosquito "burial mound" too :D

I once had an x-ray fail on aluminum pipe, because of a Kamikaze bug...

Had to move a fitting on this fuel tank. Conditions weren't very good. Wind was blowing so I had a helper holding a piece of metal to block the breeze with me trying not to lose my balance and fall out of my chair. All things considered, I think it turned out ok.
