GENERAL ELEKTRIC GE MWB 70-4 Winkel-Probe 4 MHz, 8x9mm

GENERAL ELECTRIC GE MWB 70-4 Winkel-Probe 4 MHz, 8x9mm is an angle beam probe used in industrial Non-Destructive Testing (NDT) applications, specifically for ultrasonic flaw detection. Typical application areas include:

  • Weld Inspection: Detection of defects such as cracks, voids, and lack of fusion in weld seams.
  • Casting Inspection: Identification of flaws like porosity and inclusions in cast parts.
  • Forging Inspection: Detection of cracks and other defects in forged components.
  • Pipe and Pipeline Inspection: Identification of damage such as corrosion and cracks.
  • General Material Inspection: Detection of internal and surface flaws in metals and other materials.

GENERAL ELECTRIC (now known as Waygate Technologies under Baker Hughes) GE MWB 70-4 is an angle beam probe that generates ultrasonic waves focused at a 70-degree angle. Its 4 MHz frequency and 8x9 mm crystal size offer a good balance for detecting various material types and flaws. "Winkel-Probe" is German for "angle probe." This probe is connected to an ultrasonic flaw detector and is used to analyze the reflections of sound waves sent into the material to determine the location and size of defects. Its compact dimensions make it ideal for inspections in tight and hard-to-reach areas. It is commonly used in weld inspections.
