Aluminium Welding

[afrozsh...@gmail.com]

Dear Expert

It sound very strange , but I got information there is some non - heat treatable aluminum grade of material which can welded without addition of filler wire metal.

Is it true ?

Yes, there are non-heat treatable aluminum alloys.

Dear sir,

Welding of aluminium without addition of alloying element is not recommended due loss of alloying elements in final weld. If total alloying elements reaching < 4% then weld may crack.

Refer curve: Effect of alloying additions on crack sensitivity of aluminium alloys.
