Does anyone know of a formula that will reveal the microstructure of tantalum?
We are cutting .080 tantalum in a CO2 laser. To evaluate the quality of the cut we must cut a cross-section and look at the recast layer and grain boundaries of the base metal. So far we have used the etchants we...
Thanks to everyone who responded for their valuable posts!
:-D
I did try the link to Weidemann engineering and downloaded their evaluation software. It works quite nicely! I'm gonna have to look at the NX2 supported solution via the manufacturing license.
Big thanks to all...

Hello,
Does Unigraphics NX 2.0.2.2 (or previous versions) support the engraving of text onto a solid? That is, how does one make a "word-shaped" hole?

Hello,
I have been charged with qualifying a Unitek/Miyachi High Frequency DC Inverter resistance spot welding unit for use with Nickel/Cobalt superalloys (URL: http://www.miyachi1.com/Product_Item_View.asp?ID=13).
I am experimenting with settings for .059 thick Hastelloy X, and have been...
Yes, I did email them but unfortunately they had nothing. Here is what they did have, for anyone who might be interested:
"We do not have the exact parameter you are seeking for Hastelloy X. As an approximation ,you might consider the value for latent heat of fusion for nickel, given in...
Hmmm... superposition of latent heats? That's a fine idea, wish I had thought of it. Since the target of my calculations will not involve endangering human life or sending a 3 billion dollar craft to the moon, I suppose a little bit of error can be allowed for.
Thanks for your input sreid...
What is the latent heat of fusion of the nickel superalloy Hastelloy X?
I know specific heats up to about 1100 celsius, and I can use trendline extrapolation to find ones at temps up to 1260-1355 C (melting range) if I want. But I haven't been able to find any data on latent heat for this...

Hello,
we have a Trumpf 2200 watt continuous wave CO2 laser we use to machine sheet metal. Occasionally, it is necessary to perform a laser power output calibration, or Puck Test (labeled so because the laser power probe resembles a hockey puck).
When the machine was brand-new, output...
I'm just wondering...
I've got some .012" thin test coupons of AMS 5510 (321 s/s) which will be spot welded. There is a dull gray color on the surface of the coupon, which when ground off reveals the shiny metal underneath. What is this dull gray coating? And is there any way to remove...
CWIC:
Thanks for your reply, it is quite helpful!
I don't want to beat a dead horse, but just to clarify the Net Electrode Force point...
From Table 20 and .012 Sheet Thickness:
Electrode Tip Face Diameter = 0.13 in (regardless of nose geometry)
>>> Electrode Tip Face Area =...
The AWS C1.1 spec "Recommended Practices for Resistance Welding" states in Table 20 "Spot Welding Parameters for Stainless Steels" the appropriate parameters for spot welding sheets ranging in thickness from .006 to .125 inches.
I am confused about the Net Electrode Force...
