Cook, G. E.↗
Techniques for controlling warpage and residual stresses in welded structures
Thermal pattern alteration technique controls both distortion and residual stresses in aluminum weldments. Cryogenic liquids and auxiliary heat sources are used to produce contraction and expansion of metal in the vicinity of the weld in such a manner as to counterbalance expansion and contraction caused by welding.
Cole, D. Q.↗
Renewal of corrosion protection of coated aluminum after welding
Effectiveness of conversion coatings designed to protect aluminum alloys against atmospheric corrosion is reduced after exposure to high temperature or welding. Damaged coating should be manually stripped six inches from the weld and then recoated by sponge or spray with the original solution.
Higgins, R. H.↗
Tool simplifies machining of pipe ends for precision welding
Single tool prepares a pipe end for precision welding by simultaneously performing internal machining, end facing, and bevel cutting to specification standards. The machining operation requires only one milling adjustment, can be performed quickly, and produces the high quality pipe-end configurations required to ensure precision-welded joints.
Matus, S. T.↗
Repair of honeycomb panels with welded breakaway studs
Damaged metallic honeycomb panels can be repaired by drilling holes and welding breakaway studs to both facing sheets. Minimal heat required for welding reduces distortion of highly stressed panels. Repairs can be made without the use of doublers and with greater strength when doublers are used.
Bruce, D. F.↗
Parameters for good welding of copper to nickel
Quality in welding copper leads to nickel bus wires is obtained by the mass of nickel exceeding that of copper. Welding range 2ncreases proportionately with the increase in the nickel-to-copper mass ratio up to 4-to-1.
Hall, L. G.↗
Nondestructive testing of welds on thin-walled tubing
Special ultrasonic search unit, or transducer assembly, reliably inspects the quality of melt-through welds of fusion welded tubing couplers for hydraulic lines. This instrumentation can also be used to detect faulty braze bonds in thin-walled, small diameter joints and wall thickness of thin-walled metal tubing.
Hagemaier, D. J.↗
Welding of very thin foil.
Electron beam welding method for very thin foils, discussing welding of pinhole free Ni, Cu and stainless steel foils
Fowler, P.↗
Modified faceplate assembly for stud-welding gun
Ventilated barrel assembly aids installation of studs on narrow uneven weld lands. The modified faceplate permits proper aligning of the percussion stud-welding gun in any position and on a smaller surface, and it maintains gap setting without any other adjustment.
Johnson, R. E.↗
Electrical resistance determination of actual contact area of cold welded metal joints
Method measures the area of the bonded zone of a compression weld by observing the electrical resistance of the weld zone while the load changes from full compression until the joint ruptures under tension. The ratio of bonding force to maximum tensile load varies considerably.
Hordon, M. J.↗
Improved electron-beam welding technique
Electron-beam generator produces high quality welds without vaporization by relying on the mobility and hydrodynamic properties of the material in its liquid phase. The power density of the beam is relative to the speed of the workpiece, producing an inclined weld-front.
Schumacher, B.↗
Applications of gap welding
Gap welding of electronic interconnections yields high strength joints, is easy to use, and allows visual inspection of the welding process. It is easily adaptable to automated circuit assembly.
