Open-Die Forging
Open-die forging, also known as free-forging, shapes hot metal between flat dies or a hammer and an anvil. There are no side-walls or full molds used, which allows the metal to flow relatively freely as it is deformed from different sides. Advantages Continuous Grain Flow: The grain structure aligns with the part’s shape, […]
Methods for Detecting and Verifying the Magnetic Field in MT Equipment
Here are the primary methods for detecting and verifying the magnetic field in Magnetic Particle Testing (MT) equipment, as per industry standards (e.g., ASTM E1444/E1444M, ISO 9934): Tangential Field Strength Measurement (Direct Measurement): Tool: Tangential Field Probe (Teslameter/Gaussmeter) with a Hall-effect sensor. Method: Place the sensor probe perpendicularly (tangentially) on the part’s surface in the area of […]
