TL;DR: This investigation evaluated preceramic and postceramic soldering procedures and found the strongest joints were achieved by using wider gaps and the oven soldering technique.
Abstract: This investigation evaluated preceramic and postceramic soldering procedures. Three gap spaces and two soldering methods were evaluated. Wider gaps produced stronger joints. The strongest joints were achieved by using wider gaps and the oven soldering technique. Very wide gaps (0.76 mm.) are not recommended because of possible distortion through excessive solder shrinkage. However, in practice, many solder joints exceed the 0.31 mm. recommended minimum; these joints will not show decreased strength.

TL;DR: Laser-fused precious, nonprecious, and mixed metal welds were investigated for optimum weld energy requirement as determined by tensile strength tests, and laser fusion is as good as, or better than, unions created by conventional dental joining methods.
Abstract: Laser-fused precious, nonprecious, and mixed metal welds were investigated for optimum weld energy requirement as determined by tensile strength tests. These strengths were compared to soldered unions. Laser fusion is as good as, or better than, unions created by conventional dental joining methods.

TL;DR: This is a technique for soldering ceramic-metal restorations in a vacuum-fired furnace and the various colors of impression plaster to form the key for removal of the assembly are used to prevent softening and distortion of the individual units.
Abstract: This is a technique for soldering ceramic-metal restorations in a vacuum-fired furnace. Care must be exercised to prevent adherence of the flux to the porcelain surfaces. Low-heat solders have been used, but they do not flow any better and may result in a weak union. The various colors of impression plaster to form the key for removal of the assembly are used to prevent softening and distortion of the individual units. There are several techniques described in assembling and soldering ceramic-metal restorations. This technique is direct, accurate, and easily accomplished.
