if you use something like 8260 you can use your kitchen oven to normalize the receiver afterwards. 400 degrees.

I used a mig welder for this project. I have probably 700rnds through it already, and haven't noticed any problems with the rifle yet. I will add that I riveted the trigger gaurd onto the receiveer, but the front trunion and rear block were welded in. I used an OOW receiver for this project. |

TIG welding something 70s-2 is what i would use.

If any one has a picture of where there welding was done on T/R that would be great info.

I was thinking about welding my project but ran into alot of discussions where people said mig wasnt good enough, tig was the way to go etc.... I know someone with a mig welding rig, but I ended up riveting. I would like to do a weld build in the future.

Owning a welder doesn't mean you can weld. Most MIG owners got cheap ones and have no idea how to use them.
I have a Hobart 175 MIG with bi-mix gas rig. (Argon C)2 mix) Works wonderfully on thin to medium thickness steels and SS. I'd recommend to anyone with a MIG welder to get at least a semester of training at their local CC. Preferably take gas welding and then MIG welding. You'll wind up with alot more skill at putting the heat to use and better puddle control. Right now I am quite torn between welding or riveting mine. I like the idea of not having to press the barrel out and back in! A cheap MIG with flux core wire can be much messier than a better rig with a proper gas set up. Spend a bit more money and get a gas rig. I've come to hate flux core wire! Welding with a good gas rig is almost as clean as TIG. |

VA-gunnut- Can we see some close-ups of that? I'd like to see what the interior looks like & such.

I'll see if I can get some pictures of the inside later today. |

Sorry for the crappy pics. Maybe one day I'll invest in a better camera.
   I did this one with my cheapy 110 Mig welder. It doesn't make the prettiest welds, but it works.  |

Wow, thats a new one to me..I've only seen them rosette welded. Never from the inside..

VA- how is that holding up? round count? i am very much into detail but i think that no rivits looks pretty good.

This was something I had been considering,but was told on another board that welding the front trunion could affect the heat treatment of it,making it brittle.It seems that as thick as the front trunion is,if you went slow it wouldnt heat up much,especially with a 110 mig welder.

I've heard the theory about the heat treating of the front trunion being changed. I've yet to have any problem with the rifles I've welded together. The one pictured is the third rifle I've done with a welder.
I guess if you were to get the trunion so hot that it would change color, maybe you might change the hardness of the steel. Since it is only being welded in small areas, I don't see it causing any problems. |

Thats about what I thought.That would certainly be one part you wouldnt want brittle though  I would approach it by putting a small,maybe 1/4" bead on one side,let it cool a little and go to the other side.Being you are only replacing a couple of small rivets,wouldnt take much of a weld to hold.

you cant see the welds on that one, it has about 750 through it now with nary a problem. the welds were outside welds that I ground flush it looks like its milled, pretty slick.
