Weld symbols 5

[BKM2]

In the past, our company did not include welding symbols for weldments, and are currently attempting to do so. I'm not sure how to best apply symbols on the angled cut, to the 2 HSS members mating end to end, on the attached drawing...any suggestions as to the best way to prep/weld and add symbol to the angled cut on the attached DWG?

What standard do you work to, AWS 2.4?

KENAT,

Have you reminded yourself of faq731-376 recently, or taken a look at posting policies:

What is Engineering anyway: faq1088-1484

Where I work everything is basically a butt weld or fillet weld, except in rare cases. Therefore, that looks to me like a butt weld.

I'm no welding engineer, but it really depends on your joint design. I would think you would want to put a bevel on the tubing to get good penetration. Therfore; a groove weld symbol would be appropriat.

You could also leave the edges square and leave a slight gap to allow penetration. In this case you could use a square weld symbol.

KENAT,
I'm using ANSI/AWS A2.4-98. I had not previously visited "FAQ731-376" or the other 2 sites you mentioned; today is my first time on ENG-TIPS. I do thank you for your input though.

Sorry BKM2, that's just my standard signature, wasn't directed at you personally.

Groove weld doesn't sound unreasonable but like brandon, I'm no expert. Maybe this will help.

KENAT,

The weldment I was referring to is a bit of an oddity,(2 different size HSS, & matting surfaces cut @ different angles. I have lititure with respect to A2.4 but could not find anything specific to the relitive situation.I was leaning toward a V-groove weld @ 60 degrees, resulting in a 1/4" weld
I thank you KENAT (your latest input did assist me), and everyone, for your assistence

Consider reviewing the prequalified joint details included in AWS D1.1 and consider the limitations imposed on tubular designs.

You have groove welds where butt joints occur and combinations of fillet welds and flare bevel groove welds where the gusset plates attach to the HSS.

AWS D1.1 will provide you with some direction for sizing the welds and the appropriate welding symbols needed to specify the welds you require.

Best regards - Al

Just a point of information.

I just looked through a copy of the Machinist's Handbook published by Industrial Press, 2008 edition. The welding symbols are 25+ years out of date.

Do yourself and your fabricators a favor and purchase a copy of AWS A2.4-2007 from AWS, Miami, Florida if you want to use welding symbols.

Some of the welding symbols I saw in the book predated the 1976 edition of AWS A2.4.

Shame on the editor responsible for that publication!

Best regards - Al

gtaw,

Thanks for the advice...I will be purchasing AWS A2.4-2007 as well as AWS D1.1
