No Welding Required.

Welding generates intense, localized heat that aluminum absorbs unevenly. The result is thermal stress — and thermal stress means warping. Even minor distortion can affect panel fit, mounting tolerances, and EMI gasket interfaces, creating downstream integration headaches that are expensive to diagnose and even more expensive to fix. On a program where dimensional precision matters, this is a risk that simply doesn't exist with bolted construction.

A welded enclosure is essentially a one-time decision. Once the joints are fused, any modification — adding a shelf, relocating a mounting point, accommodating a new payload — means grinding down the weld, re-welding, and re-finishing the affected surfaces. On a long-lifecycle naval program where requirements routinely evolve post-CDR, that rigidity translates directly into schedule delays and unplanned NRE costs. Field modifications are often impractical entirely, requiring the unit to be pulled from service and returned to a facility.

Weld joints are inherently less efficient than mechanically fastened ones. To achieve comparable structural integrity, welded designs require additional material around the joint — thicker walls, reinforcement gussets, or supplemental brackets. On a shipboard rack where every pound contributes to the payload budget and affects isolation system sizing, that added weight has a real downstream cost. A&J's bolted extrusion system is engineered to carry the load without the extra material — keeping the structure light, strong, and optimized from the first design iteration.
