Stainless welding - Oxy / Acetylene
Had another play with the Henrob torch yesterday having had it tucked in the shed for a while. Have some leave coming up soon so I thought I'd blow the bugs out ready for another push on the cobra build.
This time I thought I would try stainless steel welding, as the video says its a piece of cake. I am usually fairly sceptical when the video guy that has 20 years welding experience says it's easy, but, it wasn't too bad at all. http://www.clubcobra.com/photopost/d..._welding_2.JPG Basically once you have the flame set right, you just walk the weld pool along with no actual difference to mild steel. http://www.clubcobra.com/photopost/d...ss_welding.JPG They aren't the most beautiful looking welds but the penetration is good. Anyways, back into it, thought there might be some interest. I'll post some more when I have a decent crack at the aluminium welding with the torch. I imagine that will be the tough one.

Be interesting to see how it goes with Al. I would think the O2 would cause problems with the base metal oxidizing. Stainless steel is beautiful to weld with. I sleaved my control arms with stainless pipe and welded stainless to mild with 316 rods. I was amazed how nice it worked. http://www.clubcobra.com/photopost/d...ntrol_arm1.jpg The hard thing about welding pipe is going around corners. I got a few lumps were i stopped to roll over the arm (it was in a jig). Only problem with stick welding stainless is you have to be careful not to inspect it before chipping off the flux. With stainless it actualy explodes and shoots off. |
why would you 316 st stl over 309 st stl ,when welding a carbon steel to stainless.

Oxy welding aluminuim is an art. It's possible. All you have to do is master the colour of the puddle. When you can recognize the difference between molten aluminium and solid aluminium. (there's very little difference before the whole thing falls away) you can do a very nice job with gas. Make sure everything is super clean. On both sides of the weld. Inside and out. Plus the joints should be super tight.
My dad was an airframe fitter in the war he taught me when I was 16. I haven't gas welded aluminium for a while but when I do, it's a challenge and a real sense of achievement when the job is done. Have fun. |
