How would you fix this crack?

[Raspi454]

passenger side frame, in front of crossmember that transmission sits on. doesn't look too bad yet, but this is why I haven't been driving the truck.
I plan to get a welder fairly soon so I can do my sheet metal and this, but how should I attack this?

Im no expert, but maybe drill a hole at the end of the crack, then grind away to fresh metal n weld it.

should i put a piece of angle on the inside to help strengthen it a lil?

I would suggest having someone that is experienced in welding look at it and do the welding for you. Welding on a frame is not somewhere I would want to second guess the quality of work.

I'd clean it up, straighten it out, weld it, and put a fish plate over it, and/or triangular vertical gusset(s).

At least it sounds like you know what you're talking about! Lol

Jack the truck up so it sucks itself together and weld on both sides. Be sure to crank up the heat so it penetrates. Reinforce as necessary, I imagine a piece of flat stock welded down the bottom would do.

There isnt anything left to weld to on that crack. You cant weld rust.
Take a wire wheel and a grinder to that entire area inside and out fore and aft for several inches and clean it all back to solid metal.
I can see that crack is already splitting up towards the top of the frame.
I would try to get a couple of feet of good junkyard frame if you can find one.
But that also depends on your level of welding experiance.
If you do try it yourself, dont buy a cheap harbor freight flux welder.
Make sure you are actually bying a MIG welder with shieldind gas capability.
The "Easy Mig" or whatever they call it these days is not an actual MIG
That wont work.
The frame is thick enough to stick weld.
If you know how to stick thin ****.
MIG would be much easier
But you also may have no choice.
Up here the welding lawyer chickenshits wont touch that because of "liability"
Whatever you do, practice on some scrap of the same thickness first.
Watch some vids, do some reading etc.
You can do it. Its just gonna take some fuckups before you get it.
And, if you get this figured out, you will happy as hell that you did when you start the sheetmetal.
That is another level of difficult but at least you will know that

That look really bad. You have to get it down to clean shinny metal before it can be welded. As mention, you can weld over rust, buy also dirt, and paint. Drill a hole above the crack on the top side. Grind out the crack, weld it up, than add a doubler plate or angle iron ext. And weld that too. This is really not a job for a novice welder. A good welder can do a proper repair that will last.

Ditto on the welding machines and the experience to be able to get proper welds. Once you start getting close to 3/16 thickness in materials your about maxxed out with a 110 volt Mig and need step up to a 220v machine.
