Is it possible to weld schedule 10 aluminum to schedule 40? The schedule 40 has a wall thickness of about 1 inch and the schedule 10 is about .16 inchesWe are building a rocket and the body tube is made of the lighter schedule 10, while the end caps of the oxidizer tank are schedule 40The end caps are circular and will be inside the tube and will have to be welded all along the edgesWe have never tried to use two different schedules so we aren't even sure if they will hold well.

Kinda depends on your idea of healthyIf you're doing low carb, a filet minon with blue cheese butter is considered good for youlol.
Try a fettuccine alfredo with shrimpChoose whole-grain or spinach noodles, boil al denteGet Bertolli Alfredo sauce, lowest in carbs, I findBuy large shrimp sauteed in oil butter or waterCook until flesh opaque shells pink, don't overcookServe with a salad of mixed greens vinaigrette.
Shouldn't be a problemOne thing I'd advise is to bevel the edges of the caps so you get a full-penetration groove weld, instead of a simple fillet weldGroove welds have more structural integrity since there's guaranteed fusion through the entire thickness of the materialAlso groove welds require less heat input for fusion which will reduce the potential for distortion and burn-throughThis is obviously a failure-critical weldHave it done by someone with lots of experience TIG welding aluminumDon't do it yourselves since you obviously don't know what you're doingWhat is the oxidizer? Compressed N2O? Sch 40 seems a bit excessive to me, if the walls are only going to be sch 10Have you done tank stress calculations? It would also be wise to pressure test your tanks with water to check for leaks, before fielding themAlso, the type of alloy you use comes into play with regard to weldability AA 6061 is very common for applications like thisHowever 6061 is a precipitation strengthened alloyHeat causes the weld + heat-affected zone to be in the solutionized condition- which means they will lose about 70% of their ultimate strengthonly slightly stronger than pure aluminum The best procedure in this case would be to purchase materials in the all-solutionized condition, weld the parts, then have them be precipitation heat-treated after welding.
