And please put two videos for freshers like me. 1. Detail video step by step for making WPS, PQR, WQR. 2. and daily routine of a welding inspector on duty in detail with some tips to be a better inspector. Thank you.
Hi, this is available on my TH-cam channel ASME Adda for Mechanical Engineers. This video covers all stages of WPS PQR WPQ preparation in details.you can refer.
Pipe Diameter: The limitation for pipe diameter addressed in QW-452.3. The welder who qualified in 6 inch pipe cannot weld a 2 inch pipe. He can weld till 2 ½ and not less than that. Other example that is that when a welder is qualified by 1 ½ inch pipe, can weld min 1 inch and max 2 ½ inch. Dear Sir I have a misunderstanding in your statement " You write here if a welder qualify on 1 1/2 Inch Pipe then he qualify on min 1 inch and max 2 1/2 inch pipe. As per ASME SEC IX QW-452.3 said that he qualified for unlimited.
Dear Sir, Great work, please keep posting videos like this your method of explanation has cleared many doubts. I have a question if you could answer I would be grateful. 1. If a Welder is qualified for P1 then can he weld Dissimilar metals like P1 to P15f 2. And if a WPS is qualified for P1 to P1 then can it be used for dissimilar metals like P1 to P15f If all essential variables are the same as same electrode used and thickness etc.
very nice Sir Sir I have question on PQR Sir can we use a PQR "which is qualified on Material ASTM A53 Gr.A Process GTAW/SMAW Filler wire ER70 S-6 and E7018" to make a WPS for A106 Gr. B, process GTAW/SMAW filler wire ER 70 S-2 and E7018
Please refer to my TH-cam channel ASME adda for Mechanical Engineers. Video on WPS PQR WPQ qualification with initial and all stages is available on this channel.
Sir how much min.thickness welder can weld OR he qualified min.thickness limit......If I'm not wrong does he qualify min.13 mm and max.Unlim.....pls.calrify ans.
In section IX for welder minimum thickness is not mentioned. There for the minimum thickness a welder can weld is based on WPS. For example in WPS If the thickness range is given from 1.5 mm welder is qualified to weld 1.5 mm
P no. is qualified from 1 through 15F but F no. is also essential varial. If the welder is qualified with P No. 1 F No. 4 so he can not be qualified for F No. 5 which is F no of austenitic materials. I am preparing detailed videos on welder performance qualification which will cover all clauses of article III of ASME Section IX. ASME Adda for Mechanical Engineers is my TH-cam channel. You can refer this for other topics as well.
Its a good and knowledgeable video on WPQ
You may correct in supporting document under position paragraph as QW461.9 against mentioned QW469.1
And please put two videos for freshers like me.
1. Detail video step by step for making WPS, PQR, WQR.
2. and daily routine of a welding inspector on duty in detail with some tips to be a better inspector.
Thank you.

Overall its a good experience.
yes he is qualified for max diameter. maybe the youtuber misinformed in the video
Dear Sir,
Great work, please keep posting videos like this your method of explanation has cleared many doubts.
I have a question if you could answer I would be grateful.
1. If a Welder is qualified for P1 then can he weld Dissimilar metals like P1 to P15f
2. And if a WPS is qualified for P1 to P1 then can it be used for dissimilar metals like P1 to P15f
If all essential variables are the same as same electrode used and thickness etc.
I have got ur mail and will reply back to u in a while .
Thanks for supporting.
Very very useful information.
very nice Sir
Sir I have question on PQR
Sir can we use a PQR "which is qualified on Material ASTM A53 Gr.A Process GTAW/SMAW Filler wire ER70 S-6 and E7018" to make a WPS for A106 Gr. B, process GTAW/SMAW filler wire ER 70 S-2 and E7018
Nicely explained, kindly make a video on WPS with initial stages
Please refer to my TH-cam channel ASME adda for Mechanical Engineers. Video on WPS PQR WPQ qualification with initial and all stages is available on this channel.
Very good explanation
Next part didn’t come ?
Thank you
Clear explanation. Thank you

In section IX for welder minimum thickness is not mentioned. There for the minimum thickness a welder can weld is based on WPS. For example in WPS If the thickness range is given from 1.5 mm welder is qualified to weld 1.5 mm
And multiple of 1.5T if anyoune do welding below 13mm thickness@@ajay_constantine
Can you make one video on tube to tube sheet welding with GTAW Process?
Excellent explanation sir 👍.
Super expansion hope for more good videos
If a welder qualified during pqr test should we write pqr number or WPS no in WPQ record
My doubt is if welder qualified in p no 1 then he qualified and he can weld p no 1 inbetween p15F all the materials?like P4,p8,p5a
Yes. As per code. But not all clients willing to accept it. They need separate qualification
P no. is qualified from 1 through 15F but F no. is also essential varial. If the welder is qualified with P No. 1 F No. 4 so he can not be qualified for F No. 5 which is F no of austenitic materials. I am preparing detailed videos on welder performance qualification which will cover all clauses of article III of ASME Section IX.

Please share WPQ sheet for download
Only 7 variables as per SECIX, but you are saying 8 as per QW-353.
My counting went wrong. Sorry.
And thanx for the info
@@weldinginspectionndt7376 Thanks and your explanations nice.
Sir test results when u upload
Nice bro.. keep going 👍👍
I want to cswip 3.1 exam please give vedio about cswip
thank you bro!
Very great full sir ji
Thanks
Sir, root doot doot Dookie dook?
Very nice
Excellent 👌
How to review, WPS with PQR....
Please upload sec 2 part A please please
The videos on section II part A of ASME on materials will be available soon on my TH-cam channel ASME Adda for Mechanical Engineers.
What is SA in SA516 gr70
"S" prefix indicates ASME material SPECIFICATION.
"A" prefix means the material belongs to part A of ASME Section 2.
Nice Sir ji
Nice One
Wonderful ❤️❤️❤️
Spot welding WPS wpqr wow asme
Sir what does backing means ???
Sir please reply 🙏
When you weld a groove in plates and you instructed to put a flat bar between your plates. That is a backing
