Re: Question on TIG welding/annealing 4140
@ kiwi2wheels (sorry didn’t get your real name) Thanks for the tip, I’ll give Barri a buzz and ask if he can help by recommending a heat- treater. @ Arno, no hard feelings here! I realize that many people on forums are lazy a*#es, cough up a problem without doing any research themselves at all and l...

Re: Question on TIG welding/annealing 4140
@Raymond thanks for the reply and the very informative link. Lots of insights! Really appreciate that! @Arno Thanks, but I know what 4140 is. ;) I am trying to understand the key facts of the "US-annealing procedure". As I wrote I have been searching down info on the process of annealing a...

Re: Question on TIG welding/annealing 4140
Hi Vic. Sorry, I probably didn't express myself correctly. 4140 is popular in Germany but classified as not/or hardly weldable - so resellers don't have much info on the matter. I import small amounts of 4140 cold rolled annealed square stock as it is not obtainable here. It comes in handy that I ne...

All suggest not to weld 4140. Most of the teachers can't weld it themselves. We have totally different mat...

Question on TIG welding/annealing 4140
Hi all. When reading these lines please keep in mind I am from Germany. Some things that may appear to be obvious to you are not on this side of the pond.

Another newbie here
Hi all, my name is Andy and I live in Germany. I spent a few years of my life in the USA and really miss being there. As a hobbyist I do sheet metal work and welding on/for (mainly) my bikes and classic cars. I also enjoy designing/making my own tools and machines for my panel work. I practice O/A, ...
