Not sure if I used the right photo or not. I also uploaded Hearstbuilding01.JPG, and Hearstbuilding03.JPG as well. --Coro 00:27, 4 Apr 2005 (UTC)

— Looks like stone?

Shot-peened aluminium sheet, for example, resembles white stone, and was used in the expansion of the Hearst Memorial Mining Building at the University of California, Berkeley.

If you follow the link to the mining building page it specifically says that the aluminum sheet and modern design were chosen to separate the new part of the building from the old, not because they look alike. And they don't look alike, anyway, see the pic. Romana 19:57, 10 May 2007 (UTC)

I'd like to see a before and after comparison shot of a smaller part. The building doesn't do anything for me, it's just... a building. Karanne (talk) 02:31, 15 August 2008 (UTC)

source material[edit] includes the publication, The Shot Peener. Although the website and magazine are produced by a company that also makes controls and gages for shot peening, many articles are written by academic researchers and other unbiased authors. It should be watched for self-promotional material but not dismissed because the publisher is in the business. Wilhkar (talk) 16:59, 27 February 2010 (UTC) Wilhkar

Grinding stress[edit]

I'm having a bit of heartburn with this sentence: "Shot peening is often called for in aircraft repairs to relieve tensile stresses built up in the grinding process and replace them with beneficial compressive stresses."

I suggest the following instead: "Shot peening is often called for in aircraft repairs to replace the compressive layer lost by the removal of basis material.” (Or something like that)

The following information is based on my working knowledge of aircraft repair and overhaul. I realize it needs to be sourced and may count as independent research.

Shot peening is used extensively in aircraft repairs. However, it is used for fatigue life extension. Repaired areas (blended, ground etc.) have the compressive layer removed, so it’s important to put it back. As for residual stress after grinding, that was mitigated with a stress relief bake. However, we found it to be un-necessary and no longer perform that additional processing step. Alister 77 (talk) 18:47, 21 December 2010 (UTC)

Merge from Cut wire shot[edit]

Cut wire shot is small, unreferenced and would fit pretty well into this broader article. Andy Dingley (talk) 15:48, 5 January 2013 (UTC)

Merger proposal[edit]

I propose that Steel Belt: Shot Peening be merged into Shot Peening. I think that the content in the Steel Belt: Shot Peening article can easily be explained in the context of Shot Peening, and the article is of a reasonable size that the merging will not cause any problems as far as article size or undue weight is concerned.

  • In principle I'd support that. In practice though, Steel Belt: Shot Peening ought to go as an article (not even a redirect) and apart from one nice source, I'm just not seeing anything in there worth merging. It's one very minor application field of shot peening. It's also an article in great need of copyediting.
Starting from scratch, how big should the "Steel belt" section of the shot peening article be? I would suggest, not very. Andy Dingley (talk) 10:39, 28 February 2014 (UTC)

Hi, I am (so far) the main author of the Steel Belt and Steel Belt: Shot Peening Wikis. Both these items are of significant interest to small specialist groups within Industry. To date there is little information available on these topics apart from some very limited details on 1 or 2 commercial sites. The intention is to provide some clear and meaningful technical information so please bear with these two Wiki topics over the next few weeks as the information is expanded and links & references etc provided. Also I'm a new Wiki contributor so its taking some trial and error to get it right. Regarding Merging of Shot Peening and Steel Belt: Shot Peening, I don't believe this is appropriate as Steel Belt: Shot Peening is a very specialist area of metalworking using a significantly different technique and used to achieve a totally different result from General Shot Peening. The previous wiki Steel Belt Shot Peening mentioned by Andy was both created and deleted by me as part of the trial and error process in trying to produce a knowledgeable article that conforms to wiki guidelies.

I'd be curious to see a better image and description of exactly what kind of "deformation" we're talking about here. I mean, how does one shot-peen a gear? They are required to be smooth surfaces to mate properly, and grinding them afterwards would defeat the purpose. Are we talking about shot-peening the SIDES of spur gears, not the teeth? I don't get it. Also, the opening photo seems pretty pointless...can't see any detail. All I see is a building addition that appears to be made out of metal. I don't see how it's any different from other metal building siding. Also, I don't recall anything in the article about if being used for cosmetic purposes...might be nice if that is indeed the case..45Colt 07:32, 21 February 2015 (UTC)
