And a technique that uses a relationship between gradation value of infrared rays from entire state in the welding including an arc and a molten pool (hereinafter referred to as “average brightness value”) and a bead width was suggested for the automatic control on the GHTA welding. In this study, a welding speed control using the infrared images in the GHTA welding was carried out to maintain the bead width constant. The welding speed was proportional controlled, and a CCD camera was used to film the welding sate. As a result, the bead width was kept constant by the automatic control of the welding speed.本誌: 電気学会論文誌C（電子・情報・システム部門誌） Vol.135 No.11 （2015） 特集：電気関係学会関西連合大会本誌掲載ページ: 1386-1393 p原稿種別: 論文／日本語電子版へのリンク: https://www.jstage.jst.go.jp/article/ieejeiss/135/11/135_1386/_article/-char/ja/
