  1. Hi Rahul, Aluminium welding design is not a good option if your designing moment connection, since most of the aluminium profiles have less wall thickness which results into lesser weld size, also the design strength of welding reduces to almost half of the strength of parent aluminium material used due to heat affected zone (HAZ). There is a specific material strength table mentioned in ADM-2005 for the length of aluminium member in the HAZ (normally it is 25 mm from the weld line). I normally prefer aluminium welding in decorative items or any non structural aluminium elements. Regards, Ivan
