Good morning, everyone. I just started going through the 2019 ASME IX code book and noticed what I believe is an error. Let me know if I am missing something.
Table QW-288.1 for tube to tubesheet welding procedure qualifications
Under joints it shows QW-402.32 - A change in joint...
Good morning, all. I am currently working on coming up with a welding procedure to ASME VIII / IX and API 582.
Base Material
SB-443/SB-444 Grade 1 Annealed 120 ksi
Welding Codes: ASME IX / API 582
I have been informed that the choice of the higher grade of this material was to reduce base...
Good afternoon, all. I have been doing some reading of various ASM books, technical papers, and the like but I cannot seem to find exactly what I'm looking for. Here goes.
I am trying to understand whether or not to preheat my weld coupon to above the Ms point and if I should keep it at this...
Good afternoon, everyone. I'm not sure if this is the right section to ask this question but I thought I'd give it a try. I am trying to find a sheet metal supplier of:
UNS 26455
9.4610 Hastelloy C4-C
ASTM A494 CW2M
DIN G-NiMo16Cr16
I have searched online with no luck except for one company...
Good morning, all. I am designing a pressure vessel per ASME VIII Div. 1 and have come to a snag. Page 19 UG-27(c)(1) states that when the thickness does not exceed one-half the inside radius, or P does not exceed 0.385SE use this formula.
My shell will be seamless in nature. The pressure will...
Good morning, all. So our QC department is asking me whether or not we can use bar for a studded outlet (I assume for a side wall)referencing Section VIII. I am telling them no per UG-14, however I wanted to be sure I am not missing anything that may allow us to do this.
Good afternoon all. I am updating a database for our company and would like some clarification. Does B16.48 supersede all of the API STD 590 dimensions? I've looked through the forums and a few websites and it seems like it does but some companies still use the 590 code. Specific clarification...
Good morning, all. I am trying to find a standard that governs ANSI swivel type flanges. At our shop we make these, but for some reason we make the bullet part out of carbon steel such as A105 and the donut/ring out of 4130. I cannot for the life of me figure out why we are doing this and QC has...
Good afternoon, everyone. I will list all of my information/code and move on to my question.

The problem I am having is I cannot find a...
Good afternoon, eng-tips! I will outline my question, code requirements, and thoughts.
My question is about tempering temperature on 4130 and will be below. I have gone through our inventory of material to try and choose the best coupon suited for an updated SAW welding procedure with a...
Good afternoon, everyone. I have done a PQR using this:
Originally I used the PQR base metal thickness as 1/2" but the customer is saying it should be 1" on both the PQR and the WPS. This is for a 625 overlay with mechanicals to meet "as part of the design criteria" in API 6A. I am unclear as...
Good afternoon, everyone. So here is it. I'll lay out code requirements and information before getting to my question.

ASME Section IX 2015
Interpretation IX-13-19
I was reading through these and came across this one.
Interpretation: IX-13-19
Subject: QW-404.12, Hard-Facing Filler Metal Classification

Good afternoon, everyone. I have a question regarding NACE MR0175 Part 3 A7.3
"A cross-section of the weld metal, HAZ and base metal shall be examined as part of the welding procedure qualification. The microstructure shall be suitably etched and examined at x400 magnification.... The ferrite...
I have a customer requesting us to modify a procedure so that it will be good for 3/8" with impacts. The code is NACE MR0175 and ASME Section IX. Do I need to only weld up a 3/8" plate following the original procedure and have that plate impact tested or does it need to include...
Hello all and thank you in advance for any information that you can provide.
I am going to be running a coupon in the next few days overlaying 625 inconel on duplex.
Codes:
ASME SECTION IX
NACE MR0175
ASTME562
API 6A
API 6D
DNV-OS-E101
I have done several cladding procedures in the past using...
Good morning gentleman! This question regards ASME Section IX. I had a welder weld up some plates for a customer. Basically the day that all the testing was completed and the WPS was being written, a different customer asked for a WPS that included a plate thickness was not in my thickness...
Hello all. Thank you in advance for any information that you can share.
Every so often our facility needs to repair a bolt hole that was drilled in the wrong place. In the past we have qualified welding procedures to take corrective action. However the welder qualification is very difficult...
I have a WPS/ for a GTAW 625 CRO to 4130 which is heat treated. Our testing lab's WPS for my cold repair, which references the 625-4130 CRO WPS, states that the repair is qualified to weld on:
WPS
Base Metal (QW-403)
Specification - Low alloy steels (including 4130, 8630, and F22)
PQR
