- Start to finish build of a widebody PA-18 Fuselage by the Pro's at Airframes Alaska. Fully TIG welded and approximately 180-240 man hours of labor condensed into 6 minutes and 25 seconds.
Being a welder myself this is artwork in action. Thanks for taking the time and effort. Great stuff Airframes Alaska!
Jet plane. No not just only the Jet. But the turboprops also.
Consistency with the welding jig. A slick way to get it exact each time. Fun to watch. Music was a bit distracting.
Stealth
Widebody fuselage
Machine tools. For metalwork and mechanical engineering.
Amazing plane!! What’s the cabin inside width ?
Awesome works guys!! How many hours does it take from start to finish?
Generally between 180-240 man hours per fuselage depending on the configuration and mods.
Great work! Do you guys sell the wings too? Or one would have to buy from a different vender?
Hello.
Which welding machine do you use for welding tubes?
Primarily a Miller Dynasty 210
Got a jig for the PA14 build?
What method do you use for notching the tube ends?
Wielding machine. Aircraft bodybuilding
I dont think a foot pedal is a good idea for this type of welding. You lose your mobility since you can only weld sitting down most of the time. A hand switch is a must better option. Some of them you can dial in while you weld. This is 1950 welding. At least they Tig weld the chromolly.
If they post heated the frame in an oven they would get back 70% of impact and tensile strength. It will make a difference when you hit a mountain side. But I guarantee you they wont tell that to their customers.
Aircraft airframe tubing is all 4130N thin wall stuff. Most of the longer tubing in a PA-18 will be .035 and .049 (with some .058 and .065 in higher stress areas), so the benefits of renormalizing the entire airframe are nil. Some builders will reheat the landing gear attach and strut attach clusters out of an abundance of caution despite those areas being massively overbuilt in aircraft, but they are still dainty compared to stuff you'd find in surface vehicles (1/4" and up 4130N roll cage stuff with 3/16" and 1/4" plate mountings). Anything under 1/8 wall in 4130N makes post heat pretty much superfluous, as airframe tensile and fatigue performance are pretty much the same whether you do or do not. Even the FAA - famously conservative - says not worth it/not required for wall thickness in tubing or clusters of 1/8" or less. Also keep in mind that the only two generally approved welding methods are OA and TIG, although some factories have received approval for MIG under their type certificate production process (lots of controls and heavy duty QC). Heaviest tubing in the PA-18 will be the axles at .120 wall thickness (.125 turned down for bearing use) which are welded to .065 or - for folks that torture their gear - .083 landing gear legs, and that is a bolt-on to the airframe, so easy to send out if desired. In summary, post-weld heat treating is not necessary for most aircraft welds on lighter aircraft, and those builders that do post-weld heat treat, it's usually just the biggest clusters with stacks that get close to 1/4" thickness with added doublers getting a rosebud heat with the hanger doors shut and fans off.
Great at making airframes but know little about you tube videos .. All the greats on here do not use rock music and they all have narration , they turn the music off and talk some . My favorite music is rock but few seem to understand it doesn't go with airplane videos .. at all ... it becomes super annoying .. Were on here to learn about airplanes and get our music fix elsewhere
Pretty awesome once you mute the annoying song
