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.
