mirrors for welding

admin

What do you folks use for this. Specifically I have a 2" socket weld pipe joint in the 5F position about 3" off the floor and about an 1 1/2" from the wall (tie in joint). Can't see the bottom quarter (6 to 9 o'clock). Was wondering if there's a mirror with a special coating or what not that resists pitting and burning. Tried using a clear poly lens overtop, but just pitted badly and was seeing a double image.
Reply:I would heliarc that tight of a weld, personally.no spatter.
Reply:Wow, that don't sound like fun. I try to avoid getting in that situation if possible. When we get those miserable tie ins like that, I try to use slip on flanges if possible. Then you can usually seeand get the inside ok. It's sometimes about money, flanges and time will be more but the joint is easier.
Reply:A polished piece of stainless should work fine. Practice before you do the actual piece, it's a little tricky welding with a mirror.
Reply:Agree with tig the joint.  Lots of mirror welds on super heat and economizer tubes in boilers. A truck mirror on a magnetic base frees up both handsDan
Reply:I just use normal mirrors and replace them when they get to pitted to see well with. When they have room to fit my favorite mirror to use is the simple automotive sun visor clip on mirror.
Reply:Telescopic mirror, most auto part stores have them. Theyre cheap and also have a flexible head.I hate being bi-polar it's awsomeMy Heroes Have Always Been Cowboys
Reply:Thanks for the input. I don't have the option of tig welding the joint unfortunately. Slip on flanges would have helped except there was no room between the concrete and line next to it. This was a maintenance job in a steel mill and we had to make do with what we had in the time we had to do it. I like the different ideas with various mirrors and mag bases. Interesting about using polished stainless, have to give that a try.
