A group of welding processes which produces coalescence of materials by heating them to a suitable temperature and by using a filler metal, having a liquidus above 840 øF (450 øC) and below the solidus of the base materials. The filler metal is distributed between the closely fitted surfaces of the joint by capillary attraction.
Welding Tech
A method of welding by using a filler metal, having a liquidus above 840 øF (450 øC) and below the solidus of the base metals.
A weld produced by heating an assembly to the brazing temperature using a filler metal having a liquidus above 450 deg C (840 deg F) and below the solidus of the base metal. The filler metal is distributed between the closely fitted faying surfaces of the joint by capillary action.
Bonded fluxes are manufactured by binding an assortment of powder together and then baking at a low temperature. The major advantage is that additional alloying ingredients can be added to the mixture.
A defect in metal caused by hot metal cooling too rapidly when excessive gaseous content is present. Specifically, in welding, a gas pocket in the weld metal resulting from the hot metal solidifying without all of the gases having escaped to the surface.
