Testarossa's 78 KZ1000 Fighter Build

this is just a for instance,there was several different tools used to blend this weld.i am just showing it for an example.

very cool! i learned something new. i shoulda had that when I was working on my frame. too late its painted now.

forgive my ignorance....does removing the weld beads built up material decrease the area of strength between the two joined pieces...ie...does it thin out the area where a crack would begin......or are the two metals no longer seperate....at all....do the materials have no real transition from piece---....through joining weld...--to piece....and if there is a transition area...is it stronger with the bead left there.....


simple question...i just wanted to make sure i asked it right...beautiful work...very nice....


which is stronger (in theory) the before or after blending pic.....

this is for some ideas i have been formulating from watching your guys builds

That's a good question Trianglelaguna. Will be interesting to know. That finished piece is fantastic.

dang tri can you say can of worms!:laugh:

it depends on the joint and the weld.too vague?:huh:

if it is a weld i have done(which means i fit the joint i prepped and i ran the bead)and am sure of 100 percent penetration you can smooth/blend the weld with no fear of weakening the joint.
if you buttweld two pieces of the same stock together and properly penetrate,the weld is the strongest point.it should brake on one side or the other of the bead.
i would not go smoothing down welds on something i myself did not weld,such as factory welds on a frame.it seems that factory welds(from my experince of cutting up factory stuff )usually do not penetrate as deep as they should(100 percent,or all the way through the material).
if you have 100 percent penetration you can smooth the welds down to the thickness of the parent material without weakening it.
this is what i have learned from my experience as a certified (3g)all posittion welder.
hope this helped,

leon

a fully polished surface will always be stronger than the same thickness pebbled or textured surface because the polished surface has nowhere for stress risers to start to form.
cracks come from stress risers.
it is the same theory of polishing a stock con-rod if you polish it and blend everything there are no crevices for cracks to start,therefore the polished con-rod is stronger.and has less drag and,blah,blah,blah.

leon

depends on the welder and material i get...

dont blend welds you cant give the history of...great answer.....

the polishing con rods example is perfect....


thank you for taking the time to answer


i love a good hijack

if testa comes to oklahoma and kicks my a$$ for the threadjack,i will get him to give me a ride to monterey and we will throw you a blanket party with bars of soap and socks and everything.:laugh:

Code red!



I don't mind the thread jack since the content is topical. Gotta go shoot a second coat of primer. Back later.

Thank You gentlemen. The NPBSVSC includes a certificate of calibration that is traceable to NIST. This is my favorite type of innovation. It allows the regular guy to achieve professional results with commonly available tools.

Adam, this is one of those rare times that I have the tools of the trade. Literally! I run super precision small parts at work, so good measuring tools are a necessity. Here's a video of the machine that I run, program, and plan for.

i know this post is old, but WOW!

yup, that is sure draggin' up some old posts. I think Josh has moved on to telepathically controlled machines. Screw that funky old CNC technology

Well, maybe not telepathically controlled, but I might just take a side job running a five axis CNC milling center. Apparently the guy has a shop that CNC ports cylinder heads Hmmmm.... I figure it's good experience if He'll pay me what I want. Here's a similar machine in use:
