Problem: A customer needed a custom formed shape in a 24 foot sub-assembly. The tolerance in a critical venturi area was +/- 0.06" and it was inspected by a go/ no go gage. The 24 foot long sections then had to be welded together to complete the assembly (pictured above).
Solution: Northern used its extensive experience with complex forming to produce the desired shape. We then achieved full welding penetration in the 3/16" material for the entire 96 feet of welding.
Results: The laser welding caused so little distortion in the final assembly that the critical venturi area stayed within it’s extremely demanding tolerance. |
