Title:
電極チップ摩耗状態の判定装置及び判定方法
Document Type and Number:
Japanese Patent JP4703910
Kind Code:
B2
Abstract:
Welding voltage and welding current supplied to a workpiece (6) from a welding wire (3) of a consumable electrode gas shielded arc welding apparatus are detected by a welding voltage detection means (11) and a welding current detection means (12). A replacement index for an electrode tip (5) is computed by a replacement index computation means (13), based on the average values of the welding voltage and welding current during arc time. A wear assessment means (14) assesses the state of wear of the electrode tip (5) by comparing the replacement index to a prescribed reference value. When the electrode tip (5) reaches its prescribed wear limit (when its replacement index reaches the prescribed reference value), this fact is indicated by a replace tip indicator means (15).
