Aluminum welding and its uses
Aluminum welding
is known as the most intractable alloy. These are done according to the grade and type of aluminum used. There are three types of aluminum where
welding is done easily. There are commercial grade aluminum, non heat treatable alloy and heat treatable alloy. All these three contains some chemical which leads to easy
welding. The first two types consist of pure aluminum and magnesium respectively. Where else heat treatable alloy contains copper, zinc, magnesium or silicon which makes the work of
welding difficult. Due to copper you may find crack on the metal while
welding.
These generally include
Mig welding and
Tig welding method during
welding. For better result the latest technique used by
aluminum welding is the combination of
mig welding with
arc welding. These
welding feed the rod faster than other types of
welding. This welds the metal quicker without stopping for brushing or grind. There are few factors which will affect aluminum while
welding are the coating of aluminum oxide, conductivity and expansion of thermal and characteristics of melting.
