Hole Drilling - Aircraft Structure Repair | Aircraft Systems
Hole Drilling - Aircraft Structure Repair. Drilling holes is a common operation in the airframe repair shop. Once the fundamentals of drills and their uses are learned, drilling holes for rivets and bolts on light metal is not difficult. While a small portable power drill is usually the most practical tool for this common operation in airframe metalwork, sometimes a drill press may prove to be the better piece of Field welding repair - The FabricatorThe first step in welding repair is to remove the damaged metal. This can be done with oxyfuel or plasma cutting or carbon arc gouging. Oxyfuel and plasma typically are better for cutting throughmetal, whereas carbon arc gouging is better for gouging out a crack or defect without completely severing the part. Oxyfuel torches, one of the most common tools for cutting, usually can be found on most service trucks. Plasma cutters, See more on thefabricator repair of steel tubing aircraft structure by welding MachiningCorrosion Repair - an overview | ScienceDirect TopicsTraditionally, a cracked steel member can be repaired by gouging and welding at the location of crack or by welding a cover plate over the cracked region to bypass the loading. However, additional weight will be added to the structure by the welding of cover plate and fatigue crack will appear again at the location of the reweld as well.
Corrosion Protection Method for Welded Steel Tube Structures
Apr 03, 2014 · If you are TIG welding steel tube structures, the current practice is to make sure the tube inner surfaces are clean and free from corrosion prior to welding. During welding, the tube inner volumes should be back-purged with an inert gas to displace any moisture or oxygen at the back side of the welds. After welding, the vent holes should be welded closed. As long as the weld joints are sound, there should be no moisture and very little oxygen present inside the tubes.
