Why are Cannondale welds so smooth?

Maybe Bondo

However, I have heard that Klein bikes also achieve the same appearanc
without the use of the dynafile. Anyone know how Klein achieves this

There is a method for smoothing up the weld surface, which definitely
results in reduction in stress concentration, called TIG-dressing.
Essentially, it is re-melting the weld deposit metal withoud adding any new
filler metal. TIG stands for tungsten-innert gas welding method and has
been around for about 50 years now. More details available upon request -
or use Google.

TIG-dressed welds could often look like buffed and ground ones, besides
this process is superior to grinding in metallurgical aspect. Does take
approx. the same time to do this, but TIG-dressing requires high level
operator's skills as opposed to using a grinder.

I suspect that's what Klein is using.

Guess the subject header says it all. I went to my LBS and saw a
Cannondale
on the used rack. I checked the welds, and they were so smooth it almost
appeared monocoque. How does Cannondale do it? They're a lot neater than
the
aluminum welds I've seen on other makers.

My smooth welded Cannondale was just stolen 3 weeks ago. Are you in
Toronto?

Nope. Sorry somebody jacked your bike.

Yep. I've always thought they were sharmp looking bikes. Plus, you have to
give them credit for making every frame in the USA(except for the new carbon
jobber). If I wasn't a dyed-in-the-wool steel fan I would have a 'dale.

Go for it.

I'm a dyed-in-the-wool steel fan too (Cinelli Super Corsa, Colnago Spiral
Conic SLX, Condor Cycles, Wicked Fat Chance, Hot Tubes 'cross bike, etc),
and I own both a Colnago C40 and a Cannondale T1000.

The C40 is my daily ride. That doesn't mean I don't love steel.

And I do have to admit...I bought the 'dale almost a year ago, finished
(re)building it this spring, and haven't actually ridden it yet.

I'll check back when I do

Do you know why they build airplanes out of aluminum? :-)

More room for decals on those beautiful fat tubes.

Actually, Reynolds 531 tubing was used to make spitfire airplanes. In
those days the wimpy materials like aluminum were only deemed strong
enough to replace the fabric wing covers ... *grin*.
