You can expect to stay up-to-date on the latest and greatest NDT knowledge and tips with our weekly blog article.
We will also occasionally send you new product and happenings information to keep you in the loop about what we are up to at Magnaflux.
Reading or skimming through our weekly emails and articles will only take you about 5 minutes each week (we know how busy you are!). Below are two of our most popular articles to get you started.
The Y-2 is an AC electromagnetic yoke, ergonomically designed to improve productivity and reduce operator arm and wrist fatigue. The yoke generates a strong AC magnetic field for the detection of surface indications during magnetic particle testing.
Lightweight with an ergonomic grip and trigger, the Y-2 is designed for the rugged demands of field inspection. Featuring a field swappable cord and isolated trigger switch; the Y-2 is easily serviceable because a severed cord should not stop a job from getting done.
A super bright LED attachment is available as an optional item to help illuminate the inspection area while simultaneously magnetizing the part. All-in-one Kits are also available, including #1 Gray and #8A Red magnetic powders, a yellow paint marker, and cleaning cloth, for a full inspection kit in one convenient carrying case.
The operating temperature range for penetrant inspection as specified in ASTM E1417 Standard Practice for Liquid Penetrant Testing is 40°F to 125°F (4°C to 52°C), but how is the penetrant inspection affected at temperatures below 40°F (4°C) and can the inspection process be adjusted to achieve acceptable results?
To answer these questions, we evaluated SKC-S cleaner/remover, SKL-SP2 solvent removable dye penetrant and SKD-S2 non-aqueous developer at a range of temperatures in order to figure out what NDT inspectors can expect when using these, or similar quality dye penetrant products when inspecting at lower temperatures
Cleaning at lower temperatures
At lower temperatures in the range of 32°F – 50°F (0°C – 10°C), the solvent cleaner will take longer to dry.
We used 75°F (24°C) as our ambient, standard operating temperature, and observed how decreasing temperatures impacted how quickly the solvent cleaner dried. Below are our suggested drying time for solvent-based cleaner/removers at lower temperatures.
Regular upkeep on mag particle equipment is critical for non-destructive testing to safe guard inspections & reduce downtime.
Just like changing the oil in a car, basic preventive care is a cheap and easy way for NDT professionals to get the most out of your mag particle inspections and make sure your mag particle machine investments last. Will it prevent all failures from occurring, no. But I can guarantee you that if you never pull off the machine’s ventilation panels to check the cooling fans or to blow off the dirt and dust off of the rectifiers, your machine will eventually develop issues, just like a car if it’s oil hasn’t been changed in years.
One of the reasons many NDT professionals don’t pay more attention to mag particle equipment maintenance is they perceive standards like ASTM E1444 as an operating guideline instead of as minimum requirements. While it is important to regularly have your meter calibrated for accuracy, your shot timer checked and to verify output repeatability, this is not enough to keep your mag equipment at peak performance.
The ZL-400 series penetrants are water-based, water washable fluorescent materials that are an ideal solution when waste water produced during the inspection process is a concern for the operation. They are water based and contain no petroleum distillates allowing them to drain directly into the sewage system (depending on local regulations).
Magnaflux is excited to announce our latest handheld electromagnetic AC yoke – the Y-2!
Ten years ago, Magnaflux introduced the world to the first ergonomic, lightweight yoke – the Y-1. The Y-1 disrupted an industry dominated by heavy, unwieldy yokes, and brought relief to thousands of inspectors worldwide. The popularity of the Y-1 proved to be enduring – and it remains one of our highest volume products today.
