Aluminum welding process a list of frequently asked questions is as follows:

One, the coating liquid capable of dissolving aluminum in large amounts of hydrogen, hydrogen hardly soluble solid.
Two, the coating aluminum welding in the air and easily oxidized to produce alumina (Al2O3) high melting point, is very stable and difficult to remove.
Three, coated aluminum thermal conductivity and specific heat capacity of both carbon steel and low alloy steel, more than twice.
Four, the linear expansion coefficient of aluminum coated carbon steel and low alloy steel is about twice
