Partial joint penetration

Partial joint penetration

Partial joint penetration

(OP)
I am looking for a design of PJP connection. Can someone refer to a good reference? I am interested in HSS to an HSS. Thanks.

RE: Partial joint penetration

See Blodgett's Design of Weldments

RE: Partial joint penetration

Casasf:
Or look at Omer W. Blodgett’s “Design of Welded Structures” too, they are both from Lincoln Arc Welding Foundation. They are both very good ref. books on welding and weld design, etc., and they are inexpensive too. Also, look at AISC and AWS Codes and Stds. You might actually be talking about a ‘Flare-bevel-groove weld,’ if at the radiused corners of the HSS. If you are interested in meaningful discussion on your OP’s, it usually pays to give enough meaningful info. and a sketch so people can see what you are talking about.

RE: Partial joint penetration

Blodgett "Design of Welded Structures" is a great book. I think I got my copy for about $5.00. Still only $22.00.
Few picky issues:
No index.
It hasn't been updated in almost 50 years.
I'd use the line weld methods from Blodgett with allowables from the current codes. If you denote your effective penetration (place the dimension in parentheses), you can use that as your weld depth.

RE: Partial joint penetration

Jed, yes it is a great book and really does not need to be updated...

RE: Partial joint penetration

Any structural engineer without Blodgett on their shelf had better be management.

That being said, the best modern references for HSS connections are Packer's stuff. He's written a couple of books and one AISC design guide on the subject. The weld capacity per unit length is easy, dealing with non-uniform weld forces and other phenomena is the tricky bit.

The greatest trick that bond stress ever pulled was convincing the world it didn't exist.

RE: Partial joint penetration

The CIDECT design guides are probably the most comprehensive for hollow sections. Packer is one of the contributors. Blodgett's references are great, but I think most of his work was before the time of widespread use of hollow sections.

RE: Partial joint penetration

(OP)
Thank you for your replies. I will look into CIDECT.

RE: Partial joint penetration

There is one chapter in the AWS 1.1(?)that provides very good guidance. Basically there are fillet welds and flare welds.
