Hi All,
I am considering buying a small mig-welder to build some sping-loaded arms for my wooden dummy. In doing some research I quickly learnt that welding spring steel detempers the metal and that breaks close to the weld are likely. I almost abandoned the idea and then I saw:

I plan to use stiffer springs and thicker arms, but essentially this is exactly what I was thinking of doing. So I'm both hopeful and confused. It can obviously be done but I'm wondering if the creators of this product have used a special process (which I'm not likely to have access to). Or perhaps they have retempered the spring after welding. I don't know.
The spring I have (scrap from one of those '80s arm exercise machines) is a coil of 5mm steel.
Is anyone able to offer advice on this?
Thanks in advance,
Burgers
