A look back at last Wednesday when we welcomed the American Welding Society Niagara Frontier Section to Koike for a special evening with metal artist and welding influencer, David Madero! 😁

Known for his work with games like Diablo, Call of Duty, and hosting on Netflix’s Metal Shop Masters, he's currently partnering with Koike to create a large metal sculpture that will be unveiled at FABTECH Las Vegas later this year!

Attendees got a behind-the-scenes look at the project and had a chance to jump in and add to the piece themselves! As a token of gratitude, AWS gifted David Madero/Co. a fabricated appreciation award for taking the time to meet with everyone.

Thank you to all who joined us! Stay tuned when we reveal David's sculpture in October!🙌

🔥NEW BLOG POST🔥

Gravity doesn’t care how strong, skilled, or experienced you are. When a heavy weldment starts to shift, gravity always wins! ⚠️

In our latest post, we break down why safe weldment positioning is a critical skill every welder should learn before taking on larger, heavier fabrication projects.

When most people think about welding skills, they picture arc control, proper fit-up, weld quality, or the ability to run a clean bead. While those skills are certainly important, there is another fundamental skill that often receives less attention; safely handling and positioning weldments. For we...

🔥CUSTOMER SPOTLIGHT: Gernatt Asphalt Products🔥

📍Collins, NY

When production demands increased, Gernatt Asphalt Products knew it was time to scale up. After years of running a 5' x 10' KOIKE ShopPro, their team upgraded to a full-size MasterGraph Katana MGK to expand capacity and handle their countersinking requirements!

See why they made the move and how the MGK is helping them take on more work! 💪

If you love your KOIKE machine and want us to showcase your facility, DM us and let our team know! We'd love to share your story!😁

We're so proud to see our equipment supporting another NASA milestone!😁🚀

KOIKE positioners have been used by NASA many times over the years, from 29 of our TRAC-TRED turning rolls helping assemble the Jupiter-C rocket that launched America’s first satellite, Explorer 1, into orbit in 1958, to supporting the work on the Terra satellite in 1999.

It's always an honor to play a part in amazing projects like this! Thank you for sharing NASA's Kennedy Space Center!👏

Behold, Roman.

For the first time since arriving in Florida, NASA's Nancy Grace Roman Space Telescope is on full display after being unboxed and raised to its vertical position inside the high bay.

And what a sight she is! 🤩

Thanks for sharing Hebbronville Machine Shop! We love seeing a Koike Beetle out there doing what it does best!🔥🔥

Released in 1952, the IK-12 Beetle is one of the oldest oxy-fuel cutting carriages on the market, and posts like this show exactly why it has earned its reputation over the years: simple, dependable, and still producing quality cuts. 😁

Fine tuning the flame on the Koike Beetle track torch #4 cutting tip while beveling plow blades. Just like welding and watching the puddle the cut quality tells you everything you need to know if you know what to look for so that you can make your adjustments accordingly.
