極チップの損耗度検知装置に関する。Detailed Description of the Invention [Industrial Field of Application] The present invention relates to a resistance welding machine such as a spot welding machine or a projection welding machine, and detects the degree of wear and tear on an electrode tip and reshapes the electrode tip. Alternatively, the present invention relates to a wear level detection device for an electrode tip that determines when to replace it.

電極チップを所定形状に研削して整形を施す必要がある
。[Prior art] The electrode tip of a spot welding machine is subjected to a large load during welding and a large current flows through it, so the tip is easily worn out or contaminated by the metal of the workpiece, and should not be left unattended. If left untreated, welding quality will deteriorate, so it is necessary to timely grind and shape the electrode tip into a predetermined shape.

。[Problems to be Solved by the Invention] Conventionally, the timing of the grinding process using the chip dresser was uniformly controlled by controlling the number of welding points. For this reason, even though the wear of the electrode tip is low and does not require shaping, the electrode tip must be removed using a tip dresser, which may shorten the life of the electrode tip or even if the electrode tip is heavily contaminated. However, since the predetermined number of times has not been reached, the welding operation has to be continued, resulting in problems such as deterioration of welding quality.
