How to grind, blend and finish a weld seam | Norton Abrasives

Grinding wheels should be the choice for carbon steel. They will remove the weld seam quickly and since the appearance of scratches are not such an issue compared to stainless steel, are ideal for this operation. Typically, in the spectrum of 5 to 35 degrees to the horizontal (depending on the grinding wheel used) should be the target.

Reducing risk from lahar hazards: concepts, case studies ...

Lahars are rapid flows of mud–rock slurries that can occur without warning and catastrophically impact areas more than 100 km downstream of source volcanoes. Strategies to mitigate the potential for damage or loss from lahars fall into four basic categories: (1) avoidance of lahar hazards through land-use planning; (2) modification of lahar hazards through …

Principles of Modern Grinding Technology | ScienceDirect

Most grinding is conducted either with oil-in-water emulsions or with neat mineral oil or neat synthetic oil using a low-pressure delivery system. Grinding fluids reduce grinding temperatures in two different ways. The first is by directly cooling the process within the grinding contact area.
