Today Abe will test his pipe welds with gamma rays! First he will weld the 6" sch 80 coupon at the South Coast Welding Academy then take it to the Ocean Corporation to see if it passes x-rays! oceancorp.com
As a former X-ray technician, now Chem plant inspector, this is probably the best video representation of field RT of pipe welds and how things work 🤙🏼
Takes guts to do this for the world to see and judge your skills. I am a welding student and I know it's serious business. I hope to have a skill set like this young man one day. Well done, Sir.
I'm glad you had the old lady with the experience and knowledge of theory to tell you about the process. A welder is only as good as his radiograph and you passed the test.
Can’t believe they are still using tape to hold the cassette, numbers, collimator, etc. We use magnets to hold the cassette and collimator and have sets of bands for each pipe size and for different number of shots, it makes setup way faster.
@Kandela Brown not sure what you are taking about I've been a refinery inspector for almost 15 years and the only time i see digital radiography is for profile shots. In maintenance and, new constitution, and turnarounds this is the normal process..optionally you could utilize ut shearewave or phased array but most places do not trust the techs ability to locate flaws. I agree with that assessment.
@@joshuajones1319 joint geometry limits use of the digital radiography plates. And ultrasonic examination tech skills have slowed the availability of this method to be used. I understand times are changing.
@@clintg3435 ......I'm literally a CR xray tech, shooting weld quality and profiles in a chemical plant. You are talking about DR plates that can't bend, it's a little different process of capturing the image.....
very talented, I would sat that in my career I've been doing x ray welds for well over 18 years, and yes admittedly ive had a plethora of repairs along the way. majorly of them I would say self induced..
Everything looks good, Damn good! Folding the finger tips of the gloves over, never would have thought about it. Awesome shit....gonna have to give it a try here in a month or two when I can get back on my feet and walk again
I had a repair for porosity on some 3” one time. I was done welding for the day and just on standby. The techs showed me how they load film, how the figure the formulas for shot and development time, and what wire pack they use for what wall thickness and pipe size.
X-rays in welding are good. I remember back in the day picking up some blades for jet engines. And they would have to x-ray them to make sure there was no anomalies not only in the cast but the world. Weld pardon me we'll just leave that one though. Kudos keep doing it right. I'm working on it. All of my best to you and yours. No luck involved here.
Asked my backup foreman how x-ray works and got called dumb and asked if it was a genuine question sorry I’m 19 years old and don’t have 20 years experience in the trade thanks for the video helped understand a lot more with x-ray.
I had to get a bunch of 1 inch pipe welds xrayed the other day and some 1.5 inch xray. also some 2 inch 3 inch and 4 inch 6010 root on all except 1 stainless tig. all shots were clean. 1 inch 6010 welds should never get xrayed. luckily it was all clean.
3:20 I see that you are feeding the wire on average after every 3-4 complete walks of the cup. I gotta ask: how many times did you have to sharpen your tungsten? Or do you go into this pipe weld with a handful sharp at both ends ready to go? And how often did you have to let the pipe cool? For how long? or does that not affect the NDT? Thanks. Loved this video the most of all your intructionals. Peace unto you.
I always used 3/10" cassettes on a 6" pipe w/a number belt, bungie... RT Dude must be using SE75 for shooting on a picnic table Outside with No Shielding, Barricade way to small for IR192...
man i aint seen no one tape numbers out a number box like that, i guess im spoiled where im at and just build belts. also i would never shoot a spool laying on the table just making it harder on your self, set it up right, i also noticed didn't use bungees. man i cold not imagine just using masking tape all the time
also noticed he put hi penny upside down. ( numbers read left to right penny upside down) personal preference i guess i just cant stand reading film like that, for this setup i would have kept my numbers on the top side of the weld, and put my b pack astm portion so it reads( 1 astm b) on the same side and wires going down. so when i look at the film it would be whatever increment 0-1, 1-2,etc then the penny. so it should read like this 1 (increment first number , 1 astm b ( bpack) then 2( last increment). like i said personnel preference. you dont see alot of nde videos but the ones i come across i gotta pick at ahah
I've seen a lot of backfeeding videos and nobody ever talks about or shows feeding the wire while welding hope you can shed some light on this subject great video thanks
Pro tip. Cut the thumbs out of every trashed glove you ever have. Welding tips and tricks originally gave me the idea. No need to tear up good gloves every weld. Just put a thumb on like a tig finger and run with it. If you want the real tig finger I am not stopping you. I’m just cheap. And saves tig gloves from shrinking around your hands where you can’t get them off too when you forget you don’t have stick gloves on. Dunking your hand in a quench tank in welding school was kinda embarrassing to get the damn thing off.
Im a bomber in the UK and as you would have seen there was much much more wrong that just the under exposed film, I was chuckling while listening to him explain everything
I was testing for a job.I put a fifty dollar bill in my coupon. Gave it to the Welding Inspector.The X-ray guy gave me back the money he said that wasn't very funny.Nobody has a sense of humor.
No disrespect. But GTAW is generally clean process. The only defects may encounter is metal inclusion and porosity. cautious taken during welding justify RT result. However to really check skills, perform GTAW, SMAW combi. on austenitic steel (304 most commonly used, 305, 309, 310) as these may become 'sensitized' depending on 1.carbon content and 2.manner in which they are welded (technique). Performing RT after 72 hrs will reveal cracks (if any). For xtra challenges try on HK40 steels(high carbon cast stainless steels) but with GTAW only. i haven't seen those in my experience. I would love to see! I am from India btw and learning a lot through AWS. Thanks.
Go learn how to weld yourself before trying to challenge welders , oh that's right you more then likely cant , like most , will fall back on somthing that can easily be learned from reading books and watching videos
How about severe cycle… seen a lot of ppl pass X-ray until they shoot severe cycle never seen so many stainless bust and carbon … they will call porosity and slag inclusion on a stainless weld 😅 I ground into a few to find some grey spots .. tungsten inclusion … doesn’t take much to swirl in there and get trapped. Won’t burn out. Don’t get lax just bc tig is a clean process doesn’t mean you won’t catch a repair
Not sure who's neck you talking about but the only thing I see around the tech's neck is a microphone. No badge, no densitometer like good raggedy says..
Theres so much wrong with the way this guy is shooting welds, no way he just taped the increments on the pipe and used tape to hold the collimator, who taught this guy how to shoot, if anyone?
As another level 2 RT tech, guy did a great job and was professional as all hell. Needs to change out his chemicals though if they so low you need to use 17" film 😂
@@kylespirk306 he was also using 17” film on a 6” and didn’t use a number belt. Was also taping the film on there when a bungie would be a lot quicker and easier.
Anyone else that thinks they can just walk into a companies front door and have them X-Ray their welds: 🤓 The X-Ray Company: OK, she shot good! That'll be $10,000. 👍 🤣
If you can't make an X-Ray quality weld in perfect shop conditions then you should not be allowed near a welding machine. Do the test in a cramped boiler penthouse, among the super heater tubes, with a mirror. Then, if you make the X-Ray I will say, "Good for you". In a shop, no big deal.
You didn’t miss much. They lay the film out and mark its location, set the source location, crank out the source for the calculated exposure time then crank in. Then they develop the film.
You could, but you would either need to film from a distance outside the radiation area or use a tripod to leave your camera near the source. Radiation will cause ionization, but not enough to interfere with the camera.
"Why do you use lead numbers?" "Because radiation won't pass through it" Uhh... radiation DOES pass through it. Lead just absorbs more radiation due to its density. Thus not allowing much radiation to hit the film. Also saw the spacing on the location markers. Complete garbage. They need to fire that Level II. Horrible. Damn nice weld though.
