A Question On Bolsters?

Some of SOG's folding knives like the Tomcat and Winder have induction welded bolsters. What does this mean? What is induction welding?

Sorry if this is a dumb question!:p :D :)
 
Hi Chris,

Not a stupid (sorry, you said "dumb") question. Welded or soldered bolsters means that the steel bolster is welded or soldered onto the liner, not affixed in some other less secure method (like gluing).

Let me know if I answered this well enough for you of if you have further questions.
 
Thanks for the reply! So is induction welding soldering or more like arc or stick welding? I guess the induction part through me off...I never heard of induction welding.:confused: ;)
 
"Induction welding" ...

For a really technical answer, I'll have to leave this to someone with better technical knowledge than me (as you guys know, I'm in "customer service" not "technical support" ... and for very, very good reasons), but let me give this a little stab (after consulting some of our tech guys ... like my pun?).

Induction welding is the processing of passing an electric current through the two metal surfaces (in this case, the bolster and the liner), thus heating them up to the point of fusing them together.

I hope that works for you (and that I'm right).
 
I hope this clears things up....:p :rolleyes:

High–Frequency Welding: High frequency welding includes those processes in which the joining of metals is produced by the heat generated from the electrical resistance of the workpiece to the flow of high-frequency current, with or without the application of an upsetting force. The two processes that utilize high-frequency current to produce the heat for welding are high-frequency resistance welding and high-frequency induction welding, sometimes called induction resistance welding.
Almost all high-frequency welding techniques apply some force to bring the heated metals into close contact. During the application or force, an upset or bulging of metal occurs in the weld area.
 
Rob,

Ya techno geek! ;)

Ummmm ... I said that in the nicest "customer service" tone I could muster!

Ummmm ... Ooops. Take care! 'K?
 
Ok I get it now! Thank you for the techno help! ;) When I read "welded" I wondered where? I could not see a bead but this makes sense!
