Engine components are joined by numerous techniques. Wherever a joint might need to be hammered there is not much choice to drilling holes and matching nuts and bolts, the latter being one of those patented 'stop' forms that can't work loose in service.
Engine accessories – some big things like gearboxes and petroleum tanks – and – bleed connections, fuel injectors, cover plates, and several different things are kept by comparable prevent nuts stored (like others, together with the right torque) on studs welded to the motor casings.

Many motors include numerous countersunk screws. These constantly have cross-type heads, like the Parker-Kalon series. Locking wire, utilized by the mile from the Second World War, is now rarely seen. Where engine components aren't going to have to be split, the nearly universal response is some kind of aerospace bonding or welding; rivets are infrequent.

As in numerous procedures, human welders have tended to be substituted by a computer controller. When the software was perfected, this must mean completely repeatable joints with no shrinkage or distortion which has been previously difficult to prevent. One of the more conventional types used to join sheet metal work is place and arc resistance welding.
Inseam welding, the components are moved beyond aluminum wheels that by the same procedure make a constant joint. The electrode flashlight, which creates a DC cathode, is made from consumable thoriated tungsten and fitted using a gas lens' which protects the weld using inert argon, although in many instances that the whole operation occurs within a feeling of high-purity argon.
