This first pipe I believe was installed by a basket weaver, badly on the piss. I had to put in a 4" dogleg to straighten it out and relieve the pressure on a flanged control valve. 1" sched 40.

Second pic is replacing a section of rusted 1/2" sched 80 pipe, about 12ft up, frustrated access on one side, treated sump water dripping down onto pipe caused my bead to freaking explode a couple of times just as I was sealing it up. I think the chemicals were crystallising into the joint causing some kind of contamination. Cut and grind.

Yep. I should've taken a before pic. Out 4" in two directions. Discovered when the solenoid valve was removed for service and the pipe sprang apart. There must have been huge force on the valve casting and flanges all that time. Absolute awful and dangerous original install. The welding done on it makes you spit as well.

Amazing that they let hacks work on something that could be so dangerous if a failure ever occurred. Now they have the right man on the job. Nice work!

What process did you use when welding it back together? Nice fix, I like the clamp attachments, Do you use them frequently?

All butts were tigged in two passes with vee prep, no land and 3/32" wire gap.

Both clamps are stronghand tools commonly used by pipe welders to align pipe joints.The lower one comes in two sizes, this one is the small vice grip clamp and is good down to 1" pipe. It grips 3/4" & 1/2" pipe but not enough gap is left between the jaws to get a tack in. The upper c-clamp has one v-mag jaw only, a little bit fiddly to get the alignment right but leaves a gap even on 1/2" pipe to tack through.

I use these clamps all the time, great time saving tools that gets the all important alignment right.

I believe the the comments when the the pipe sprung apart were something like " oh snap, that's something you don't see everyday!" followed by a brief discussion concerning the lineage of the original welder. :)

The lineage of original welder was the first question I asked myself.

What was the lineage of this welder you speak of.
A student now but really want to weld everyday. Want to learn everything about everything. Want to become a knower of all and master of none.

We can only speculate cause we don't know his identity

Probably better this way. If you found out who he was he might have a problem coming his way from you.
