Video Borescopes for the Casting Industry – Slag Reduction

The third post of our series of Video Borescopes for the Casting Industry provides a look at the slag reduction process. In case you missed it in our posts on coating inspections and weld inspections, here is a quick recap on the metal casting process.

Metal casting, the process of pouring metal in molten form into a mold to create a casted part, is used in a variety of applications; from art to industrial parts. Because of the need for complete precision during the entire casting process, quality control is a must. Only through a visual inspection of the internal passageways can professionals be absolutely sure that there are no defects or foreign object debris (FOD) that could cause problems down the road.

Overview of slag:

Slag can be defined as refuse produced as a result of melting nonferrous material(s?) that have a high melting point. In the casting process, slag is infamous for being the residue left behind in the melting process of metals.

The reduction of slag on casted parts is extremely important. Refuse of any size can lead to parts not fitting together properly, which would result in restarting the casting process for those parts all over again. Slag, which can also fall under the definition of FOD, can mean partial blockages in internal passageways, residual scratches, and other surface impurities.  Inspectors can greatly reduce the occurrence of slag by making sure RVI of all casting is part of the casting company’s quality assurance procedure. Video borescopes, such as the VJ-Advance articulating video borescope, have camera and video capabilities that are able to document internal slag findings, allowing you to prevent future slag formation.

The fourth part of our Video Borescopes for the Casting Industry series will be posted soon! In the meantime, you can find out more about how the VJ-Advance video borescope is the perfect tool for seeking out slag residue by visiting the RF System Lab website or by calling (231) 943-1171.
