Background

In the field of corrosion protection, the corrosion potential of an evaluation object is generally required to be measured to determine the corrosion state of the evaluation object, for example, in the field of cathode protection, whether the protection potential of a protected object meets the requirement or not is required to be measured, and in the field of corrosion evaluation of concrete structures, the corrosion potential of steel bars in concrete is often measured by a half-cell potential detection method to determine the corrosion state of the steel bars.

The existing on-site wire connection process adopts a welding process to ensure that the wire is in good contact with an object to be detected. The traditional lead field welding has the following problems: firstly, under the actual situation on site, welding conditions are not provided for many times, and the risk of electric leakage exists in a moist closed environment without a power supply; secondly, the preparation process of welding takes too long. The device is used in cooperation with an induction heating welding device. The welding device is simple to operate, safe and portable (low working voltage), and has small influence on the surface of a workpiece. In addition, in the actual welding process, the brazing filler metal or the welding rod is operated independently, and meanwhile, the contact of the welded parts needs to be considered, so that the process is complicated.

Therefore, a method and a device which are simple and convenient to operate, consume less time, have small influence on the surface of a workpiece, can ensure that a lead is effectively and electrically connected with a detected object, and simplify the field workload are needed.
