DiaMet Hardness Software – Weld Testing Using Vickers Hardness Scale

Weld Image

Welded joints are nowadays indispensable in the automotive and aviation industry. Welds usually combine metallic components to form a structure that is then assembled in production and assembly with other subassemblies. The welds must be able to withstand extreme loads as they are the weak points of the construction. Weld seam inspection is thus a …

Cuts Like a Knife … Hardness Testing Matters

Cutting Edge Hardness Testing

In the highly competitive cutting blades indus­try, it is vital for the blade to have sufficient hardness to retain an edge, while too hard can cause brittle failure. When hardened materials are ground, residual heat may alter the microstructure and soften the blade edge. Testing the hardness of the cutting blades becomes challenging as indents …

Material Thickness When Choosing a Rockwell Scale

Hardness Scales

Are you concerned about which Rockwell scale to use for thin materials? Of primary importance in Rockwell scale selection is material thickness. Since the 30 Rockwell scales are distinguished by total test force as well as the indenter type, a load or force that is excessive for a given material thickness will ultimately be influenced …
