American Welding Society Forum
Hi everybody MERRY CHRISTMAS im new to here this is my first topic and post and i have been looking around to find pictures and info about how a good downhill root and cap pass looks like ill be glad if anybody has some pics inside the pipe of the root pass and how it needs to be. I know both walls needs to be welded together but i would like to see some of your roots and also pics of your cap pass.... thanks 4 your time and have a great day
what kind of downhill weld u asking for.. i would say it would be mig gun hardwire or pulse ? i would never weld downhill if its stick rod ,tig,fluxcore mig gun.. i myself inspected weld testing downhill isn't the best idea for piping jobs ..
but thats the way the pipelines do it
stick rod 1/8" 6010 root and cap 5/32" or 3/16" 8010
here are some pictures had to downsize them to fit sorry about quality hope it helps you
Is that 1st pic your bead?
first one is bead #2 is the bead ground out #3 is the hot pass #4 cap the last picture is the inside of the pipe
i used 1/8 5p+ for bead and 5/32 8010 all the way out. All downhill
ok I was just wondering Ive never had a bead look like that unless thats just thin wall pipe.
it is a piece of 12" thin wall
Hey wagon 83 dont want to bust your b:::: or any thing like that but that looks like a pile of sh"" work to me what grade are you in or did sourdoe i ment sourpu:: show you that

Isn't it great when someone chimes in that can barely type and busts your chops when you are trying to help someone out. I am sure the pics were appreciated.
Agreed, my thoughts exactly. Thanks for the pics!
The best comment I have ever found for people like that is simply say, well I guess your lucky cause you can kiss my A** and I can,t. To bad he is to good to help or can't figure out how to upload his own pics.

those a super sweet welds there tozzi
hey hand you done good just messing with you keep on keeping on life to short
It is all practice, just keep at it and you will get the hang of it.
alright guys dont hit me up to hard i know im still learning i having trouble on the cap im learing on my own and i got some advice from here it has help alot
dont look too bad man looks way better than mine lol... i always get stuck welding that junk pipe that just melts away when u touch it i had to turn my machine down to 190 and about 25 to keep it from blowing out... and some of the pipe was magnitized
on your filler metal try making it even all the way to the top of the bevel.that way when you cap it will be even all the way around. and only grind in the weld zone .not on the pipe wall. it will make a big difference on the way it looks.
thanks for the advice ill will try that....also how does my root looks?
Not to bad but as far as the root goes, when I was first learning I kept working at it to get it as uniform are I could get all the way around. It all depends on the inspector but all inspectors will want penetration all the way around but some will want it to look just like a wedding band all the way, tie ins and all. Keep working at it, its looking good.
