RE: [MW:4362] Aluminium Welding

Dear Nimesh,
 
I have practicied many welding processes and consumables for welding of 50xx and 60xx grade AL.
 
you can use both procedures TIG and GMAW.
 
if you use TIG your machine and power should be set up on AC.
 
if you use GMAW your power should be DC. try to use ESAB make ER5356 or 5183 gmaw wire in DC current.
 
the Al you want to weld is non heat treated alloy. with above written GMAW wires you can get a very good result but dont pass the interpass temperature which is required to be max 130 degree c.
 
best regards,
Elshan.

Dear All,

Need to weld Aluminium of grade 5052 for 5mm thick plates in both BUTT and FILLET welding. Kindly suggest which type of power source (Arc, TIG, MIG) will be most suitable for this application. 

We tried using LH409 welding electrode (3.2mm ) in EP mode. We get a good weld result with BUTT joints but Fillet doesnt hold any strength , any reasons why ?
