  • Mending the unmendable: A new method for restoring fractured metals

    Researchers develop a new metal-healing technique that fully restores previously unrepairable metals, presenting sustainable options for manufacturers.
    Tensile test for welding procedure. It, also known as tension testing, is a fundamental materials science and engineering test in which a sample is subjected to a controlled tension until failure.
    Also known as a tension test, a tensile test is a fundamental materials science and engineering test in which a sample’s strength and quality of a welded joint are evaluated by subjecting a test specimen to an increasing tensile load until it breaks. It helps identify defects that can weaken the weld and ensures the weld meets the required standards for strength and quality.
