In this video I show what process I perform to properly restore the condition of aluminum castings to the original. The aluminum casting that I weld comes from a Jawa 50 moped. After watching this video you will be directed to how the repair of welding of motorcycle, moped or any castings looks like. I would divide the video into 4 steps 1 - inspection and determination of the profitability of repairing the casting 2 - Very thorough cleaning of the casting 3 - Selection of parameters, filler metal for aluminum and welding of aluminum 4 - Finishing of the final welded aluminum element The welding technique I use (Tungsten Inert Gas) TIG. Filler metal AlSi5 - AlSi12, the closest to AlSi9 casting. Green tungsten electrode 2.0 / Argon gas. Welding of aluminum castings is considered complicated due to the specific properties of aluminum, such as its high thermal conductivity and tendency to oxidize. This requires the use of appropriate techniques, materials, and aluminum filler metal to obtain durable and high-quality connections. ????
