Aluminium is well used in various industries. In St Helens, aluminium welding is dependent on the properties of aluminium itself. Its high thermal conductivity, high thermal expansion coefficient, low melting temperature and aluminium oxide surface coating influence how it is welded. The melting point of aluminum oxide is almost three times the melting point of pure aluminium. This aluminium oxide film absorbs moisture from the air, particularly as it becomes thicker. Moisture is a source of hydrogen, which can hinder the durability in aluminium welds. Hydrogen is soluble in molten aluminium and will therefore easily enter the weld pool. As the aluminium solidifies, it will retain much less hydrogen since solidification will reject hydrogen. With a fast cooling rate, free hydrogen is retained within the weld and will cause porosity. Porosity will decrease weld strength and ductility, depending on the amount. We take all this into consideration in order to ensure your welded aluminium is strong.
