Welding Symbols and Definitions

A 'weld symbol' is similar but different in that it is one specific symbol for one specific kind of weld. In my article on the different types of welds I showed you the 5 basic welds: fillet, groove, surfacing, plug, and slot. There is a specific weld symbol for each of these weld types, which is just one small part of the entire welding symbol.

Understanding the Marking System for Grinding Wheels

The peripheral surface speed, given in metres per second. For example, 80m/s. The rotational speed, given in revolutions per minute. For example, 8500rpm. For smaller grinding wheels (below 80mm in diameter), the maximum operating speed is provided on a separate notice which must be stored alongside the wheel.

Surface finish - Wikipedia

Surface finish, also known as surface texture or surface topography, is the nature of a surface as defined by the three characteristics of lay, surface roughness, and waviness. It comprises the small, local deviations of a surface from the perfectly flat ideal (a true plane).

Surface grinding - Wikipedia

Surface grinding is used to produce a smooth finish on flat surfaces. It is a widely used abrasive machining process in which a spinning wheel covered in rough particles (grinding wheel) cuts chips of metallic or nonmetallic substance from a workpiece, making a face of it flat or smooth.
