What does he do weld 'em?

(b) Aluminium slag from solid rocket motors

They clearly refused this slag from another time.

There's space to experiment and to weld and to test things.

Apparently, IMLI also dumps its waste slag outside its factory gates.

(b) Aluminium oxide slag and micro particles from orbital solid rocket motor firings

Well, those sand dabs of yours are just terrible. The way you weld them with that acetylene flavor, the...

Hence, aluminium slag from orbital solid rocket motor firings must be regarded as a relevant space debris source.

And what you do is you put it together in three layers, you weld it around the edge, and then you inflate it.

Hence, the main problem in modelling the generation process of such aluminium oxide slag is the lack of reliable data.

Villagers collect it and smelt it in woks over open fires in their backyards, trying to sell the extracted lead content of the slag.

When the manufacturing process or the materials make it necessary, the shells shall be suitably heat treated to guarantee adequate toughness in the weld and in the heat affected zones.

Of these sources, only the coolant droplets and the large scale fraction of the aluminium oxide objects, called slag, are of some interest in terms of collision cascading.

As a result, the current models only reflect a coarse impression of the generation and release mechanisms for aluminium slag, particularly in terms of mass or diameter distribution.

Other mission related particles may be generated unintentionally, as in the release of slag (up to several centimetres in diameter) during and after the burn of solid rocket motors.

The precise nature of the amount and distribution of these slag ejecta are unclear, and the improvement of solid propellant and motor insulation to minimize the released solids is difficult.

Future analyses will have to show the level up to which the slag population may accumulate, taking into account the influence of sink mechanisms like atmospheric drag or solar radiation pressure.

At DARA DLR a study concerning the actual aspects of the space debris discussion is nearing completion, comprising, for example, additional space debris sources (RORSAT droplets, surface degradation particles, Al2O3 dust slag from solid rocket motor firings) or the minimum spacing required between the graveyard orbit and the geosynchronous Earth orbit (GEO).

While the ejection of micron sized Al2O3 particles in the course of solid rocket motor firings is a well known fact that can easily be derived from the large amount of aluminium additives in the charge, the exhaust of relatively large slag objects in the burn out phase was discovered only recently.
