That appeared to be an almost impossible repair - kudos for accepting a challenge like that. Because that casting was designed to be exposed to salt water, I imagine they actually used better casting material than would have been necessary otherwise.
I think the worst I did was an oil pan on a skid steer. While on the skid steer. Used a spool gun. Ugly when done but it held oil. I like your videos. I teach now and share them with my class.
Thank you for simple, clear instruction. l am welding a damaged quad engine lower casing with a hole and broken away edge. l am using a cheap lift inverter tig 165, not sure will do a good job. Any advices appreciated.
pre heat with a torch. get to at least 400 deg then weld at full amps you might get a puddle. if you haven't welded aluminum before. don't make this your first project
@@MeltinMetalAnthony Thanks, l m refining my tig set up for ac, thicker tungsten to do the cooking/filling after preheating the job. Will practice on junk cast alum parts(a bad cut off saw) till good results acquired. l arc alum sticks, its good bulk jobs.
Great videos. Wear some robber gloves when you use acetone. It absorbs thru your skin and goes straight to your liver, or kidneys, don't remember which. Stay safe.
5356 is generally used on unknown aluminum alloys and more so on dirty cast. 4043 works though but keep this in mind… unless using a spoolgun, spoolgun welds with 5356 filler are terrible in my opinion and spoolgun on a job like this should only be done as a last resort if you have no access to AC TIG.

l have a spool gun set up for alum, will try on bulky works. Tig seems doing a finer patches/build ups.
Great video and thanks for sharing! Stay Safe!

@@MeltinMetalAnthony Thanks, l did the repairs by Duraweld rod, as my repair spots on quad lower casing are all none critical structural areas.
Use Phosphoric Acid to chemically clean Aluminum, (Alumi-Prep). That is what is used in Aircraft Aluminum Alloys. Lime-Away may work.
never thought of that
Only need H pure tungsten for a transformer machine I believe correct me if I’m wrong
Can you repair cast aluminum with alumna weld ?

the 5356 wouldn't take
totally agree
Which price this mashin.
Mention your settings more.
That looked absolutely horrible to do, well done....
Came here after welding a pencil sharpener back together
