The authors examined the methods of high frequency induction soldering, especially Loop-method, other than the gas flame soldering which was known generally. The details which was done are: (1) about the form of induction coil, and the relative places of the coil and restrative appliance, and some supplementary appliances of them. (2) about strength of soldered joints of Co-Cr wire using silver solder and Pd-solder, and observation on the corrosion of soldered-joints by the scanning electron-microscope. (3) about the comparison of the characteristics of Co-Cr wire by means of high-frequency induction heating and gas-flame one. (4) about the examples of soldering of porcelain crown-bridge and clasp wire attached on the dental cast, and possibility of soldering techniques of them on the dental cast. The authors found that the high frequency induction method was preeminent from the other method on the point of (a) the characteristic of heated wire, (b) the strength of soldered joints, (c) the easiness of operating of them, and (d) the possibility of soldering using the high-melting point of Pd-solder, and the soldering of them on the dental cast. Therefore we can enough respect the application on the dental area of this apparatus and this techniques of the high-frequency induction soldering.
作者研究了高频感应焊接的方法，特别是环形法，而非一般熟知的气焊。所做的详细工作如下：(1) 关于感应线圈的形式、线圈与固定装置的相对位置以及它们的一些辅助装置。(2) 关于使用银焊料和钯焊料焊接钴铬丝的接头强度，以及通过扫描电子显微镜观察焊接接头的腐蚀情况。(3) 关于通过高频感应加热和火焰加热对钴铬丝特性的比较。(4) 关于烤瓷冠桥和附着在牙模上的卡环丝的焊接实例，以及它们在牙模上焊接技术的可能性。作者发现，高频感应法在以下方面优于其他方法：(a) 加热丝的特性；(b) 焊接接头的强度；(c) 操作的简易性；(d) 使用高熔点钯焊料进行焊接以及在牙模上进行焊接的可能性。因此，我们完全可以重视该设备和高频感应焊接技术在牙科领域的应用。
