Translation of "Water blasting" in German

Water abrasive suspension blasting is used for example in degrading technology below and above water.

This may take place by means of knurling, laser ablation, hammer brushing, high-pressure water jetting, sand blasting or similar processes.

Thus, more than simply the draining concept of creating wave motion in the water surface by blasting a plurality of jets of displacing material or fluid across the felt width in front of, or in, the convex deflection zone may be utilized to remove as much fluid from the felt as possible.

If the abrasive medium located in the pressure container is used up the pressure container must be filled and the water abrasive suspension blasting must be interrupted during this time.

The nozzle array or the individual nozzle entails thick supply lines, which are difficult to move, in conventional high-pressure water blasting installations.

The high-pressure water blasting cleans the surface and produces undercuts on the surface of the insert, leading to, e.g., good securing of the casting metal after it has solidified.

The hard, silicon-rich phases are torn out by the water-blasting and leave behind the desired undercuts at the surface.

They believe that the "hard" methods (high-pressure water, sand blasting, hydro sand blasting), which are frequently used because of the low cost (ECU 15/m2), are too hard on both the building and the envi ronment.

As in the pre­vious case, there remained a cavity which apparently had to be "filled with water" before blasting into the seam in order to preclude the possibility of a firedamp explosion.

The front wing anhedral also helps to keep the wing tips away from the water surface while blasting upwind or carving a hard turn.

The removal of the mold material of the lost mold occurs, conventionally, by means of knocking the material off, vibration, use of pressurized air, water or sand blasting, ultrasound or through rinsing with acids or alkaline solutions.

The reaction layer 43 may also be removed by water blasting, in which case once again a small amount of energy is introduced.

Hitherto, components which have been coated with coatings of type MCrAlY or ZrO 2 have had the coating removed, for example, by acid stripping in combination with sand blasting or by high-pressure water blasting.

A drawback of the currently usual methods of core production is the fact that the removal of the cores from the molded part is possible only with an extremely high expenditure (e.g., combustion, high-pressure water blasting), the distribution of the sands within the core is inhomogeneous, and crack nuclei exist which may lead to breaking under thermal/mechanical loads, inter alia.
