... are higher than gas melters, although melting times may be longer, but metal quality is higher in melting aluminum because hydrogen absorption from fossil fuel decomposition is eliminated. Some smaller electrically heated melting furnaces may employ sidewells for charging and melt treatment such as degassing...

... metal to meet the target fill time. Once the metal has fallen its maximum height, a filter can be useful in reducing the speed of the metal, typically from speeds in the range of 2 to 4 m/s (6.5 to 13 ft/s), capable of generating masses of air bubbles and oxides, to less than 1 m/s (3 ft/s...

... definitively shown that the beneficial action of a ceramic foam filter derives approximately 5% from filtration (depending on the quality of the metal) and 95% from improved flow ( Ref 13 ). Therefore, it seems likely that the benefits of using filters in filling systems arise mainly from the reduction...

An area that has received greater investigation is the spectral range of the electromagnetic radiation emission from the metal vapor/plasma plume. Monitoring this spectral range provides means to infer the quality of the laser weld process...
