#automotive #welding why doesn't anyone tell aluminum welding tricks like this I use lpg gas and co2 gas, for welding wire I use homemade cast wire (previous video) not many know how to weld aluminum using lpg gas
I haven't seen this quality of aluminum welding in over 30 yrs, my son's god father who worked in a sheet metal fabrication shop was the go to guy to do aluminum welding, and he was the best of the best, and this gent doing the welding in this video should be proud of his work, kudoos to him and keep up the great work, as for the keyboard Karen's, well all I gotta say is if don't know then shut up watch and learn !! Have a great merry Christmas
I would use mention instead of tell, but I get the picture. This guy could even fix a 6061 aluminum bike even though 40,000 psi is plenty of tensile strength. Stronger than carbon fiber in general.
Keren mas 👍👍👍 thanks udah share.. Mas mau tanya perbandingan tekanan/presure gas CO2 sama LPG nya berapa untuk menghasilkan las2an alumunium yang solid??
Aluminum is hard to weld, because it doesn't puddle up, like steel does, instead it justs gets a wrinkle look, then a few seconds later after the wrinkle look, the aluminium just falls apart, so its crucial to get your welding rod into the wrinkle area, just as it wrinkles, them keep moving, before the whole wrinkle area, just falls off, in one big blob. Also, its good to use an aluminum flux when welding aluminum, for a better looking weld.😁👍
Takes a bit of practice but can make a very sound weld using gas torch with aluminum arc welding rod as a filler rod. Can use in the field without electricity. Was a common practice in the early part of to 20th century. Easier to do if you have a pair of the old blue lensed gas welding googles so you can see when the base metal starts to melt. Over the past few years I’ve done several successful repairs this way and have tested several samples that achieved full penetration welds stronger that the base pieces being welded.
The way I’ve been doing this, the weld is fluxed and shielded by the flux on the arc welding rod I’m using as a filler rod. I’ve also done some welding with no filler rod or with bare aluminum filler strips where I cleaned all materials by sanding or brushing with an un contaminated stainless steel wire bush and welded using the aluminum flux sold by Tinman Technologies (a good source for speciality tools for sheet metal work and sheet metal welding) - off hand I don’t know what is in the flux which is supplied as a white powder you mix up with distilled water.
Learned this 40+ years ago in high school. It’s best to clean all surfaces and wipe them down with acetone before welding, makes a cleaner, stronger and better looking weld
Looks a really skilful job. What gas is used here propane or poss Argon or a mix?. Steel rod to remove Oxidisation and filler rod where necessary?.great anyway.👍
Most of the time, he's manipulating the weld puddle with the butt end of a steel welding rod. Then adding a little filler, and repeating the process. He is melting the parent metal, and adding filler, literally the definition of welding. If you think it looks easy, its because you've never tried to do it.
What I see is, the process of extracting dross from the surface of the puddle by using the arc welding rod to collect it by a scratching technique. The preliminary weld to secure the parts in place is cleaned in preparation for the filler rod, after the application of the filler rod the weld is again cleaned by pooling and scratching. The same thing happens when you melt ally for casting, before pouring ,the dross is removed with the help of a steel sieve. Great work...
Salut! La lucrări de tinichigerie de îndreptare ce pot folosii pentru finisaje la temperaturi joase atât pe aluminiu cât și pe metal, ma refer sa nu mai intre asa mult chit, mulțumesc
How do you know if your aluminum is hot enough to weld, but not so hot it falls apart? 1) you should clean all that comtanination out. 2) turn your torch to where it is just burning acetylene. You want that orange/black sooty flame. Put the torch on the metal and get it black. 3) Turn your torch to the proper heat for the job. 4) now heat the material. The black soot will burn off when the metal is ready. This works well before you TIG weld or any type of aluminum welding.
Irmão essa solda não está penetrando só está colocando material em cima se vc tivesse usado esse eletrodo na máquina de solda esse trincadinho solidária só com um passe . Se fosse ferro fundido a ser soldado aí sim e bom dar uma aquecida na a peça antes de fazer a soldagem e após a soldagem uma estufa para ele não resfriar rápido Agora alumínio vc pode trabalhar com a operagem da máquina bem baixo porque ele aque rápido por inteiro
well let's see.....it shows him at the start of the video opening the valve on an oxygen tank so I would guess it's oxygen and propane....but we'll let you figure it out Einstein 🤨
Please correct me if mistaken and supporting evidence. This cannot be welding but brazing or soldering. The base metal is not forming a puddle; not a fusion of base and filler metals.
This is gas welding. He is forming a weld puddle, and manipulating it with the butt end of a steel welding rod. The filler material is a fat bit of aluminum, which is added at times, then he goes back to working the weld puddle with the steel welding rod. When you see the welding rod, he is not adding filler, just working the puddle. The parent metal and filler are all blended together. That's not low temp zinc he's using for filler, it is aluminum, which means the parent metal is being heated to the melting point.
@@vandalsgaragetambién por cuestiones físicas y técnicas la soldadura queda con pequeños poros internos q debilitan el material, no va tener la misma resistencia una soldadura realizada como en el vídeo a una por electrodo revestido o por proceso tig siendo este último el más resistente, esto no quiere decir q este mal lo del vídeo solo q es otro proceso y no es el óptimo pero cumple su función.
