Weld grinding/finishing standards(?)

Weld grinding/finishing standards(?)

Weld grinding/finishing standards(?)

(OP)
I've been looking around for any standards or best practices that help a designer (me) communicate the finish quality of welds - both to my fabrication vendor and to my customers.

Bottom line, customers expect everything ground and polished (for free) like a medical device and fab vendors expect one pass of a power grinder to count for "ground" welds. I can't find anything in AWS D1.1 related to this.

Before I write my own standard covering grinding, max undercuts, allowable pockets, surface roughness, 8x10 glossy color photographs of the crime scene, etc, does something exist?

RE: Weld grinding/finishing standards(?)

There's not standard that I know of, but when this issue has come up in the past for me I have used a note similar to "Welds to be fully blended with base material (ground/polished until no evidence of a welded joint is visible)"

I think this is one of those unfortunate cases where no symbol or standard exists, and you have to include a big long sentence on your drawing. I hate that.

RE: Weld grinding/finishing standards(?)

Check "Architecturally Exposed Structural Steel".

RE: Weld grinding/finishing standards(?)

simple run test samples of 125 micro, 63 micro 32 micro 16 micro
precision ground parts vs hand ground parts is like night and day.

precision ground are are 32 or better.
hand ground 250-125 micro. must be noted hand ground or precision ground.
