A surface of the parts with which the resin is brought into direct contact is carburized at high concentration by a plasma carburizing method. Then, a carburized layer of high carbon concentration is formed on the surface of the handened part.

Inventor: FUJII TAKANARI
IPC: B23K11/24
Filed: 1987-09-30
Abstract: PURPOSE:To prevent welding quality from being deteriorated and to prevent work from being interrupted by processing a magnetic field intensity signal of a magnetic sensor corresponding to each inside conductor to calculate the variance quantity of the magnetic field intensity and comparing an average of N times with a preset threshold to detect disconnection. CONSTITUTION:The magnetic sensor Sa, etc., are arranged corresponding to each inside conductor 2a, etc., and the magnetic field intensity signal outputted from each magnetic sensor (gauss meter G) is processed by a statistical method to calculate the variance of the magnetic field intensity. The disconnection of the inside conductor is detected by a comparison between a characteristic value found by calculating the average of the variance quantity of the N times in the past and the preset threshold. Even if the variance quantity is changed greatly by accident according to the welding position, the variance quantity of the N times is averaged and its influence can be reduced and the disconnection can be surely detected. By this method, the monitoring position is always taken and the sudden interruption of the work can be prevented.
