I'm in the process of developing a WPS for 9% Nickel plate, however there has been some feedback in regards to the possible introduction of magnetism to the plate by using the GTAW process. Can anyone elaborate please, I've never heard of this before, also is the a process to ensure this doesn't...
I'm looking for validation on this point or a positive proof to negate my approach please. If I have a welder qualified to GTAW (TIG) carbon steel only without backing (gas or plate) and he utilizes F6 GTAW to obtain a fillet weld, could I use the same welder to obtain a Stainless Steel fillet...
PA2KS, many thanks for this link, even the ability to catalogue and update welders is looking to be a very useful tool. We are in a constant flux (pardon the pun)with regular shutdowns, new welders and constant testing.
Could anyone recommend a reliable programme I could purchase, download and install to help generate new weld procedures? Preferably for North America, Canada in particular.
Many thanks,
Thank you, that is very helpful, Google is not broken, but over and above the information on line I was looking for a hands on approach also. Thanks again for taking some time out for this.
if your design and operating temps do not go below temperatures in the tables of B31.3 then no impacts are required to qualify your PQR, however if you are using low temp carbon there may be more information required from your design department, honestly without your range of temps and design at...
Looking for some tips in the process's applications for both GTAW (TIG) and GMAW (MIG) to this particular duplex on 1/8" plate....back purge pressures...cleanliness...speed...amps ...stringers as opposed to weaves...I would think that a weave would lead to lack of fusion because of fast freeze...
Hello everyone, hope you all had a pleasant weekend. I'm looking to find where it references the requirement of two gauges when doing hydro testing. (high point--low point)This is for piping and so far I have had no luck in B31:3. Also the length of time when gauges should re-calibrated, is this...
Under B31.3, are there any requirements in regards to design or registration governing the fabrication of a hydro-testing manifold.
Thanks for the time spent on this.
We are in the process of fabricating a test header that will be utilized in pnuematic testing here in Canada. Does the header need to be designed and stamped and approved by the provincial authority, and, what code or specification can be used to determine the testing required on the header...
