My question is about best method different than PMI to identify different filler metals used along the completion of piping weld (SMAW), specifically how to diferentiate 6010 & 8018 filler materials.
Any input will be appreciated.
Without cutouts sent to a lab, I think you will have a problem.
What you could do is make a set of "mock up" joints. With what is actually required for fillers, and what you suspect you are seeing.
Then, Do the PMI on the Mock up joints, compare to the PMI on your production work that is suspect and your PQR.
The concern is that second passes were made with E6010 instead of E8018 as stated in the procedure.
If it's on the second pass I think there is no way to see it unless cutting it out and comparing with another welded joint, because PMI doesn't work well with carbon steel (experience with BRUKER S1 Titan not sure of another handheld XRF or spark).
Hope you find another more practical solution.
There is not problem to cut it out and then after what´s the best method to use, is metallography, chemical analysis, hardness...
I'm surprised that the Welding Procedure doesn't allow for a "hot-pass", this is pretty common with pipe welding to prevent burning through your root when you go to the low hydrogen electrodes. Maybe it should...
The "old school" welders always want to do that hot pass thing with 6010.
I haven't seen a hot pass allowed with 6010 on B31.3 gigs in about 20 years.
love 6010 for the hot passI haven't seen a hot pass allowed with 6010 on B31.3 gigs in about 20 years.
been 20 years?? time flies for old blind welders
Case 1 :
I want to weld AFNOR 15CDV6 to AFNOR 15CDV6 forge block of dimensions 350*350*450 (T*W*L). Which filler metal is preferred FC 90T5-k2 or E 100K3C. Also is PWHT mandatory??. If so is the material prone to reheat cracks so what precaution to be taken while welding and post welding .
I want to weld AFNOR 15CDV6 to IS 2062 E 450; forge block of dimensions 350*350*450 (T*W*L) and plate of 10 mm thick . Which filler metal is preferred FC 90T5-k2 or E 100K3C. Also is PWHT mandatory??. If so is the material prone to reheat cracks so what precaution to be taken while welding and post welding .
kindly help me out
Does presence of Ni ( 1.5-2%) in weld metal composition and also Ni in Weld consumable ( Like E90T5-K2) helps in reducing the Reheat cracking in Cr-Mo-V steel.
Kindly help ??
what is the suitable welding consumable for welding HY 130 plates 20 mm thick also plz give the source from where we can procure the consumable ??
To get better responses from people, for each new question/topic you have, open a new "Post".
That way you don't interrupt other people's threads and can focus on yours.
To answer your HY 130 question...
The tempered martensite in that steel is susceptible to hydrogen cracking. Use a filler and/or process to minimize the risk. I cannot give you specifics and I suspect others will tell you the same thing. It takes lots of time and money to develop processes.
Wow, this post took a dogleg left like my 3 wood...
That's why my 3 wood stays in the bag....
Thanks alot. I was unaware of new post.....
