Putting together the "Mast Puzzle"

As I mentioned in another post the mast was joined with an internal piece and secured with stainless steel rivets but I never was happy with this formula because this is like having a sword of Damocles on you. live with the possibility that one day the mast split and fall on someone or on me is not recommended or intelligent. It's okay if you're always going to sail in the harbor under the protective sky of a protected area but this is not the case.
Then before assembling the mast I took it to a place where they welded airplane parts to be soldered with "Tig" welding.
There has always been controversy about welding aluminum masts for fear of being deformed but when using "Tig" this does not happen. The first thing to do to achieve a good welding job is to find out what type of aluminum alloy your mast is made of. Once you have discovered this, the welder can use 4043 or 5356 welding rods.
The first is for aluminum alloy masts with silicon and the second is for magnesium alloy masts.
In this way, the fusion bath generated by the welding machine and the argon gas produces a smooth weld without deforming the metal from which the mast is made.
After all this it was necessary to place the rails of the main sail securing them with the "tap and die" system. I chose this "tap and die" system because it is much safer than just putting rivets and it gives you the possibility to disassemble to do maintenance whenever you want.

Also reinforce the "Mast head" with welding. Originally this mast system has attached the mast head with a pair of bolts but having investigated on masts similar to this discovered that many of them break or fail because the mast head is disconnected from the mast because the galvanic corrosion that occurs between the stainless steel bolts holding the mast head weaken this mast area causing it to fracture and fall on your head and end up in the cemetery in the worst case.
