A brazing apparatus to join a first component and a second component includes a heating element configured to melt a ring located at a joint between the first component and the second component, and a probe configured to contact the ring. A position of the probe is biased toward the ring. The probe is installed at a probe support. The probe is movable along a probe central axis relative to the probe support. A sensor is operably connected to the probe and is configured to determine movement of the probe along the probe central axis. The movement of the probe is indicative of melting of the ring.

A resistance soldering apparatus suited for soldering an electrical terminal to a glass surface and a method of using such an apparatus is described herein. The resistance soldering apparatus includes an electrode having a distal tip and an electrical terminal having a first major surface in which an indentation is defined and a second major surface opposite the first major surface on which a layer of a solder composition is disposed. The indentation is configured to receive the distal tip of the electrode. The distal tip of the electrode is placed within the indentation and an electrical current is passed through the electrode and the electrical terminal, The electrical current is sufficient to heat the electrode and melt the solder composition on the second major surface.

An electric heating device includes a body and a heating head connected to the body. The heating head includes an electric heating wire and a heat storage member. The electric heating wire includes a first section and a second section connected to the first section. The first section is made of pure nickel. The second section is made of ferrochrome. The heat storage member is mounted around an outer radial periphery of the second section. The heat storage member is made of porcelain clay. The electric heating wire is connected by sections of three different materials so that the heating head can be raised to a very high temperature with extremely high heat generation efficiency, and the electric heating device is not easily damaged by high temperature.
