I split this topic off of the thread it was thread-jacking.

Not the most polite "hello" we've seen, nor the most coherent question, but I invite polite discussion to help this fellow out, if possible.

On that note. Hello and Welcome. Welding down hill on pipe can be done while getting good penetration. This involves proper materials, techniques, and practice. Not all welds are equal and if you by chance have any pictures of welds in question then please post them. Then the wisdom and experience of many eyes can give you an accurate answer.

If your pipe weld is going to be xrayed that means there will be a weld procedure specification in place. This will specify what rod to use and which direction to weld. If you deviate from this specification your weld will fail inspection.

The visual inspectors on site on test day will look you out if there doing there job. If they give you a WPS then that's the law. What kind of problems are you having on your bad side?

Old indian trick - When tacking pipes or tubes up for a test I use three tacks about 1/2" long. When placing the tacked coupon in position to weld (6G) I rotate the bottom tack so that the end of it is dead bottom with the remainder of the tack coming up the weak side. That gives you a little advantage on the weak side. When hot passing or sticking out my good side welds start past dead bottom also. Never been called on it and I've taken a LOT of test's this way.
