Success Story - Electron Beam Welding of Stainless Steel Bearing Seal Support for the Aerospace Industry

Posted by Chris Kielb on Jan 6, 2022 3:21:19 PM

When an FAA customer asked us to repair a bearing seal support with only two days' notice, we welcomed the opportunity to prove its dedication to satisfying their expectations.

Following customer specifications and PWA 16-2, we utilized a purpose-built fixture to position the part under the beam. The repair consisted of welding AMS 5613 (410 stainless steel). We achieved the requisite weld dimensions of 6.4" in diameter, a .070" joint thickness, and a weld penetration depth of .070" (100%). Dimensional tolerances achieved were ±.0005".

After stress relieving at 1050 degrees Fahrenheit for a specified cycle, the bearing seal supports were ready to be returned to our aerospace client. Another perfect welding job performed by one of the country's finest welding outfits.
