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.

This post continues our series of “Video Borescopes for the Casting Industry” with a look into a different kind of inspection. In case you missed our last piece, here is a quick recap on the metal casting process.

In our first post of the series, we covered video borescopes for coating inspections. This post is going to take a more detailed look into weld inspections.

Overview of welding:

The process of welding is, put plainly, to join two casted parts together. While welding sounds simple, welding precision is crucial. Broken casted parts are not unusual given the brittle nature of most cast iron.  However, any missteps or overlooked defects can result in disaster and may mean that the part is unusable; causing the entire casting process to start completely over. Welding is an important solution to this issue since it is sometimes used to repair defects discovered after a piece has been casted.

Video borescopes, like the VJ-Advance articulating video borescope, allow maintenance technicians to internally check that the weld is free of gaps and is fully penetrated. Medical-grade quality cameras offered on high-quality videoscopes provide the opportunity to take crisp images documenting the integrity of the weld, which allow casting professionals to feel confident that their parts are free of defects. Completing remote visual inspections with a video borescope helps assist professionals in making sure that welds are intact, and parts do not need recasting.

We will post the next part of our Video Borescopes for the Casting Industry series soon! In the meantime, you can find out more about how the VJ-Advance video borescope is the perfect tool for weld inspections by visiting the RF System Lab website or by calling (231) 943-1171.

That is why using a video borescope during the casting process, and final inspection can save companies time and money.

Video borescopes are utilized for a significant amount of inspections during the casting process. Over the next few weeks, RF System Lab is going to provide an in-depth look into how videoscopes like the VJ-Advance articulating video borescope instill confidence in numerous casting quality checks.

We’re starting off this blog series with coating inspections.

Once a part is casted, it sometimes needs a secondary polishing, which is completed by precise methods such as electropolishing. These secondary polishings, made of thin films of material, finish off rough passageways and add protection to the surface of parts. This procedure is crucial for many industrial uses – especially when the parts are being used for food and drug industries, where a smooth surface free of FOD is essential in order to keep the final products clean and pure.

That being said, internally inspecting coated parts is a must in order to confidently confirm that they are free of burrs, cracks, drippage, and even corrosion further down the line. Video borescopes with extremely thin insertion tube diameters, like the 2.8mm VJ-Advance video borescope, are the ideal tool to inspect these coatings. Videoscopes enable NDT professionals to easily observe and take high-resolution photographic evidence of the internal condition of parts, which is a necessity when confirming condition. Quality checks with a video borescope greatly reduce the risk of defects in the coating of a casted part, which also reduces overall expenses by preventing contamination and cracking in coating.
