WPS for Skewed T Joints

WPS for Skewed T Joints

WPS for Skewed T Joints

(OP)
Hi all,

I've been asked to put together a few WPS to cover the range of skewed T joints that we need to qualify, but I have very limited experience with the welding code. Since we need to qualify by test, I'd like to have the fewest number of WPS that can cover the various types of welds that we are using.

The plate thickness of steel that we use ranges from 3 gauge to 12 gauge, and sometimes two different gauges may be used together (i.e. 3 with 7). The T joint angles can range from 150 to 30, and the fillet is always just on one side. My question is, how many WPS will I need to cover these various parameters with angles and material thicknesses? Also, what if we use different types of steel?

In addition, is there an easy way to determine the effective throat that will be required for each setup? How do I determine the fillet size for each condition?

Any help would be greatly appreciated.

Thanks,
M

RE: WPS for Skewed T Joints

What is your applicable code of construction? Your thicknesses may drive you to sheet steel specific codes for the 12 gauge material, possibly more if you are using materials other than carbon steel.

HI M,

PLEASE SPECIFY WHICH STANDARDS ARE YOUR COMPANY FOLLOWING. DEPENDING ON THAT I CAN HELP YOU.

We are following ANSI AWS D1.1-2010.

RE: WPS for Skewed T Joints

I HOPE YOU HAVE A COPY OF D1.1 PLEASE REFER TO SECTION 3 FOR PREQUALIFIED WPS. IT WILL HELP YOU

RE: WPS for Skewed T Joints

Most structural people do not work with gages, they and the code (D1.1) is written for fractional or decimal thicknesses. Make your life and ours a little easier and provide that thickness in inches or millimeters wn working with the structural welding code.

Best regards - Al
