okwelder82,
Let me guess, you busted due to slag entrapment?
Year and a half or so back I posted an inquiry in this forum pertaining to E7048. I had to test some seasoned Union Boilermakers of whom several I knew professionally and to be good welders. 2 out of 14 passed
My tips for running this would be...
1) Avoid this rod at all costs! Test on it only if you just want to brag to your buddies all about it, are really hungry, don't care if you flunk, your ex-wife or Dominatrix didn't punish you enough ("you're a bad, bad welder, kiss my whip!"), or the Repo man just hauled your rig out of the bar parking lot.
okwelder82, you say you've got a couple of 10 pound cans of this crap? Sell it to the first schmuck you can...tell 'em it's the best rod made since 5P++...tell 'em it's a welders best kept secret and is known as 10P+++ amongst those "in the know"!
2) Run HOT!!! Any doubts, turn it up 10 more! You will know if you are too hot if the rod is 1/2 way burnt, melts off and falls out of the stinger.
3) Grind between passes, until you're wore out. Then give the grinder to your helper and have him grind some more.
4) Use a really steep leading angle, just as if you were running Exx10 on pipe.
5) Work the (well ground) sides real good.
6) If you don't think it went in good...You are right ...It didn't. Repeat steps #2-#5 or save yourself further anguish and use step #1
7) If you think it went in Good...You are Wrong! ... It didn't ... Repeat steps #2-#5 or save yourself further anguish and use step #1
8) Use an old hood. Don't want to throw your good one across the shop and break it.
I remember back in the '80s? maybe reading about this in the Welding Journal and it was developed to bring the Pipeline Industry up to speed and allow the Down Hill welders something familiar to run, yet give the Metalurgists and Engineers their "highly revered" Low Hyrdogen weld deposits. It never took hold in the industry and I'm sure...because it is a SLAG TRAPPING SOB!!!
BTW I did run a sample 3G down and it bent. There were "indications" on all the straps...it bent..I swear.
This is based only on my limited experience.
Can anyone can honestly chime in and say this is their rod of choice. If so okwelder's got a deal for you....
