This week’s topic for RF System Lab’s Video Borescopes for the Casting Industry blog series is burr reduction. Our previous blog posts have covered residue reduction, coating inspections, weld inspections, slag inspections, and form inspections. In case you didn’t get a chance to view those posts, here is a 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 Burr:

Burr is a kind of residue that is leftover after the part has been casted, cut, or drilled. Specifically, it is a rough edge or area that remains after those processes. Any debris or rough edges that remain in the casted form affect the integrity of the part and must be removed. However, many passageways, where burrs are located, are extremely thin and hard to inspect without the proper tool.

This is where video borescopes come into play. Super-slim articulating video borescopes are the perfect tool for navigating around tight corners and inspecting small passageways to ensure that they are clear of burrs. Metal Casting quality inspectors can use videoscopes to confidently confirm that casted forms are free of residue and are cut or drilled exactly as required.

We have one last post in our Video Borescopes for the Casting Industry series to look out for! In the meantime, you can find out more about how the VJ-Advance video borescope is the perfect tool for inspecting all components of casted forms 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.

Only through a visual inspection of the internal passageways can professionals be sure that there are no defects or foreign object debris (FOD) that could cause problems down the road. 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.
