Reply:If the cap was freehand, why did you try to weave it? With a bead that narrow, there is no real reason too.Have we all gone mad?

Reply:Showdog: On that pipe that you beveled and did the root pass followed by the stitching, I was wondering why the V groove was so wide. I'm not a pipe weldor, so I can't say anything about the beveling, but it just seems to me that the bevel was way wider than it needed to be just to get a good root. Of course a wide bevel requires lots of follow up passes to weave it all back together. I was always under the impression that the bevel only had to be wide enough to get the torch in and get a good full root pass.Edit: Looking at the photos again I think I might have misjudged the diameter of the pipe and the wall thickness. It looked like a large diameter pipe to me at first. Was it some sort of small dia. pipe with thick walls? If so, I can see the reason for what appeared to be a wide bevel.DougLast edited by DougAustinTX; 04-06-2011 at 01:10 AM.Miller Syncrowave 350Millermatic 252/ 30A spoolgunMiller Bobcat 225g w/ 3545 spoolgunLincoln PowerArc4000Lincoln 175 Mig Lincoln 135 Mig Everlast 250EX TigCentury ac/dc 230 amp stickVictor O/AHypertherm 1000 plasma

Justin T (can't quote your post): Not looking too bad, but In the first foto you need to give the purge more time to work, the gold bits of the root are aceptable but the grey areas show too much O2 content. Also, you'll get better results if you don't stop and start so much when running the root pass.Last edited by Baila La Pinza; 04-06-2011 at 05:46 AM.
Reply:wow nice pics yall!! @Baila Thanks for the info I will try that today and post new pictures.

Reply:Originally Posted by arcboyHow do I do that. I just took a weld test on some SS and I prepped it myself and pretty much burned it up. It was 2” tubing something like 3/16 thick open root not purged. It was good enough for them but I thought it was nasty!!I don’t have a lot of experience in pipe and I want to learn. I have 48 feet or some 6” 1/4 wall pipe and a Dynasty 200 that I am going to practice my technique. I would like to know how to make some good SS welds on pipe/tubing without burning it up.I was always told that its a good rule to for example to use 1/8 gap, 1/8 filler or 3/32 gap, 3/32 filler and walk the cup for pipe is most consistent.I have a lot of experience on every type of process and material except pipe and this is where the money is at.
Reply:It would help if I would add the link I meant to. http://www.millerwelds.com/resources...t-I-do-at-workMaybe this will help answer some questions for you.
Reply:BC how did you clean the throttle shafts up? I tried some stainless chemical clean once and it did a good job but it stank and the parts had to sit for some time.Pie cut exhaust.
Reply:just one question - Is that grey-red colour of weld on exhaust pipe ok or the weld will crack and rust ? Will pulse welding help when welding 1-2 mm stainless ? I can make beautiful welds on 3mm and thicker stainless but 1-2 mm stainless is pain in the *** even with #8 gas lens.

Reply:i was always told that you have to watch your heat when welding ss...the heat effected zones on some of these look as if it was not a worry
Reply:It all depends on the application. Most of the welds you are seeing here will never be pushed to their limits and don't need to keep radioactive materials or the like inside. If we were looking at pics of stainless welds in a nuke plant there would be no colors at all to look at. To make perfect stainless welds is quite time consuming and unnecessary in most applications.

To make perfect stainless welds is quite time consuming and unnecessary in most applications.all the ss welds i have ever done had to be practically color free and it did take a very long time...i know in the food prossesing industry it has to be the same way..from what i was told is that if the heat affected zone/weld gets to hotit changes the molecular structure of the stainless and inturn alows it to rust
Reply:Yes food and medical industry calls for nice stainless welds as well. Here is some "medical" stainless work I did one year for valentines day.
