Summary:To make it possible to start early laser welding of various sheet metals by shorting a time until registering processing condition suitable for an unregistered sheet metal in a processing condition storage part.SOLUTION: A processing condition selection part 42 selects processing condition of a sheet metal W having quality of material similar to that of an unregistered sheet metal W in which processing form is same as that of the unregistered sheet metal W and a plate thickness is same as or close to that of the unregistered sheet metal W with reference to a relationship of processing condition stored for each quality of material of the sheet metal W, and the plate thickness and the processing form of the sheet metal W. A weld control part 44 performs a processing test for the unregistered sheet metal W by controlling a laser welder 14 while changing processing parameters of the selected processing condition on the basis of the afore-said condition. A processing condition registration part 48 specifies the processing parameters on the basis of the test result of the processing test for the unregistered sheet metal W, and registers the processing condition of the unregistered sheet metal W in a processing condition storage part 36.SELECTED DRAWING: Figure 2 【課題】未登録の板金に適した加工条件を加工条件記憶部に登録するまでの時間を短縮して、様々な板金のレーザ溶接を早期に開始する。【解決手段】加工条件選択部４２は、板金Ｗの材質毎に記憶された加工条件と板金Ｗの板厚と加工形態との関係を参照しつつ、未登録の板金Ｗに近い材質の板金Ｗの加工条件であって、未登録の板金Ｗの加工形態と同じ加工形態でかつ未登録の板金Ｗと同じ板厚又は近い板厚の加工条件を選択する。溶接制御部４４は、選択された加工条件に基づいて、その加工条件の加工パラメータを変化させながら、レーザ溶接機１４を制御して未登録の板金Ｗに対して加工試験を行う。加工条件登録部４８は、未登録の板金Ｗの加工試験の試験結果に基づいて、加工パラメータを特定して未登録の板金Ｗの加工条件を加工条件記憶部３６に登録する。【選択図】図２
