i take it your a tube welder?

have you ever welded P91 and 450 degrees preheat?

Are you with the Shaw Group? We have worked with them just completed one gas power plant and another one will soon be done .

I don't work for Shaw.

Bechtel

Hi Jeb.
I doubt my welding would get me qualified with Shaw or Bechtel.
I have a friend that wanted to learn how to weld so I fired up the old Montgomery Wards 220 Buzz Box in the garage and gave him a few lessons, "he was very impressed with my skills”.
He pursued that line of work and eventually went through Chevrons Boilermaker welder program. Needless to say, after that, he wasn’t quite as impressed with my talent.
I could have used a few tips from you guys this winter when I built a wood stove chimney for our place out of some 6”well casing , so far no leaks and and it hasn’t fallen over "yet".

dennis its unfortunate that your friend turns his nose up now. if it wasnt for you his interest in welding may have never materialized. i respect the garage fabricator very much. they have many tools at hand including the two most important and versitile....Imagination and ingenuity. we have to follow very strict rules and regulations, it can get a bit redundant. but it pays good!!!

did you use a wire welder on the pipe or your tig rig?

Where was he when Stephanie Lewis broke my heart back in the 7th grade?

Yea, 15, P22, P91.

I like 91 better. I don't get into the preheat or soak afterwards. I just weld. I think they soak 91 at about 1600 after the weld. Hour an inch or so. I do worry about pass temps though.

But I don't go out but about a month or two a year. Sometimes a week or two at a time. Turn off the cell phone and disappear for a little. But really I don't do a lot of the run of the mill - tube welding in power plants like you are thinking of. Too many responsibilities to run the roads too much though, we run a family business, do a lot of thin wall (sch 40 and 80) tight tolerance piping for critical applications. Money has to be right and short spurts for me to go. No more than I do it, I will lose it and start busting. In the family business, I very rarely pick up a welding helmet.

Orbitals and automatics are coming on strong. 10 years will show a lot of changes in thick wall welding and fabrication procedures. If I were you I would get started with them now. They are working out a lot of the issues that made them impractical in the past. They will never completely replace hand welding though.

Jeb.
I made the root pass with TIG then the final with the MIG. I didn’t mean to make my buddy
seem like a bad guy, as you know to get to that level its a lot of hard and frustrating work. He is just a much better welder. Has trouble tying his shoes though.

Has trouble tying his shoes though.

thats a welder for you. some times people can get to big for there britches. the guy that got me started said that i would be a better welder than him one day. i still respect him. he pointed me in the direction that i needed. the junior always should respect the senior regardless of ability!!

you are a humlbe man to let it go and bask in his glory and accomlishments. you have launched him into a place you will never see and that is a good thing. no worries.

i am interested in what you have to post on testing things to destruction. i will post some cool stuff this week. i have tube welders, pipe welders, structrual welders, and some specialty welders to test this next week. just last week we did some titanium tests. i think we have one more welder that willl have to test on that too!!!

more pics to post soon.

Mike, I worked with this guy in Alaska and then up in Borger, Tx. He's something else : combo welder/poet/singer songwriter/comedian. Bought one of his cd's from him, pretty entertaining!

[Dennis D]

Thanks for your interest Jeb.
Here are a few more tests I did when I was building my Gyro. Not all of the testing was to test welds. Some were to give me confidence about a material thickness choice or a component’s capabilities... Please excuse some of the welds, some were just sloppy and others were done poorly assuming that the actual welds would be better / stronger and not fail.

I’m very interested in seeing anything you can post on how professional testing is done.
There has to be more to it than a home made press, converted hydraulic jack and a ball peen hammer.
