Measuring device with two registration elements which determine if a feature to be measured is between two established limits.
Gouge
Surface imperfection, deeper than a scratch, often with raised edges.
Grain Direction
1 Crystaline orientation of material in the direction of mill rolling. 2 Orientation of a surface finish generated by abrasive method.
Grinding
Process of removing material by abrasion.
Grippers
Material clamping devices often serrated for additional holding force to restrain material during a die operation.
Grit
Mineral particles used for abrasive metal removal.
GTA Welding (Gas Tungsten Arc)
Or TIG Welding (Tungsten Inert Gas), a welding process that uses a tungsten electrode to produce the weld, allowing for greater control and stronger, higher quality welds.
