Hardness Testing of Metal Parts
Hardness testing is a fundamental and essential method in materials science for evaluating the mechanical properties of metal components. It measures a material’s resistance to permanent indentation, which generally correlates with properties like strength, wear resistance, and ductility. The methods can be broadly categorized into three main types: Indentation, Rebound (Dynamic), and Scratch Hardness Testing. Indentation hardness is […]
Compared with traditional welding
Laser welding vs MIG welding Laser welding has an extremely low heat input, allowing for precise welding with minimal deformation and an aesthetically pleasing finish. In contrast, MIG welding involves wires that act as both the electrode and filler metal, requiring continuous energization and melting. Therefore, the overall heat input is relatively high, which can […]
