The demand for bending on thin wall stainless steel grows in industries that require the safe, clean transportation of liquids and gases. Below you’ll find the Axenics thin wall steel tubing size chart to give you an idea of our most-common requested bends. Thin wall...
The phrase “great news” has been scarce this year, but we feel strongly that we’ll be using it more in 2021. One, we’re seeing signs of robust growth within the semiconductor industry that should continue for at least the next calendar year. Two, Axenics is moving...
Many journeyperson welders consider argon the perfect shielding gas for precision welding and fabrication. Axenics utilizes 99.9% pure argon for tungsten inert gas (TIG) welding for customers that require high-purity welds for their liquid and gas transfer systems...
Non-destructive weld testing critical for hydrogen fuel cell components
The call for cleaner energy gets louder every day, which is why Axenics puts a strong focus on welding and weld testing for hydrogen fuel cell components. Original equipment manufacturers demand the highest purity level for fuel cell technologies, and we deliver exceptional products by implementing tactics such as:
- Continuing education for our welders and technicians
- Eliminating potential contaminants by completing projects in a Class 100 cleanroom
- Performing non-destructive weld testing on components during each step of the process
More OEMs are getting onboard with clean technology, including introducing hydrogen energy solutions into automobiles, construction vehicles and other modes of transportation. Aside from additional consumer vehicles receiving hydrogen power, we see an increase of vehicles that perform functions indoors using fuel cell technologies as well. For instance, food service companies use forklifts and other vehicles that transport products within warehouses powered with hydrogen technology. This solves the problem of chemical byproducts damaging the edible inventory. The byproduct of a hydrogen fuel cell is simply water.
Your next process control solution begins here.
The increase in projects based around hydrogen fuel cell power systems does not translate to a decrease in Axenics’ in-house safety measures or productivity. Cross-training our team ensures there are many hands available for welding tasks. Staying on top of new techniques keeps our welders sharp as they tackle increasingly intricate weldments.
The delicate nature of hydrogen fuel cell components means we are performing much of the welding in a cleanroom setting, which is maintained daily. Potential contaminants such as dirt and dust particles are kept out, tooling is regularly cleaned and technicians wear protective gear to maintain the purity of your products.
Nondestructive testing on hydrogen fuel cell components
Non-destructive weld testing (NDT) is an essential part of the process in component production. Axenics’ technicians regularly perform NDT on three-pass heat exchanger hydrogen fuel cells, evaluating the performance of the components. NDT locates any potential defects and discontinuities, while maintaining the component’s functionality. These three variations of NDT are commonplace at Axenics:
Visual Weld Testing is just as it sounds — using trained eyes to find potential leaks. Technicians review the component for a range of possible problem areas, including, but not limited to:
- Weld fissures
- Surface flaws
- Material corrosion
- Banding distortion
Hydrostatic testing uses water and air pressure to locate leak points. Helium leak testing via pressure testing and vacuum testing are two NDT processes used to ensure your components are defect-free. Axenics’ performs helium leak tests on any component used to transport a gas, such as hydrogen.
Axenics accelerates hydrogen fuel cell component production to lower energy costs and provides longer lifetimes of products for our customers — to promote a cleaner environment for everyone.
The semiconductor industry has remained pandemic-proof through 2020 so far. And, the outlook for 2021 looks fantastic with a projected 12% global growth, according to Future Horizons. Axenics is a longtime fabricator of components and a service provider for Tier 1,...
Our lean manufacturing practices come in very handy when there’s a shift in the speed of business. Fortunately, the new year sees a burst of growth continuing, specifically with component manufacturing for the semiconductor industry. Since late summer, we’ve been...
