Title (EN) WELDING SYSTEM
(FR) SYSTÈME DE SOUDAGE
(JA) 溶接システム
Abstract:
(EN) The purpose of the invention is to provide a system for reliably determining the presence/absence of a weld defect. The welding system according to the present invention has: a rotating machine for causing a member to be welded to rotate; a welding unit for welding the member to be welded, which has been caused to rotate by the rotating machine; a measurement unit for measuring the size of a melt pool when welding is being performed by the welding unit; and a determining unit for determining the presence/absence of a weld defect on the basis of a predetermined threshold value and an actual measurement value including the size of the melt pool measured by the measurement unit, the threshold value being determined according to the circumferential angle of the member to be welded which has been caused to rotate.
(FR) L'invention concerne un système permettant de déterminer de manière fiable la présence/l'absence d'un défaut de soudure. Le système de soudage, selon la présente invention, comprend : une machine rotative permettant d'amener un élément à souder à tourner ; une unité de soudage permettant de souder l'élément à souder, qui a été amené à tourner par la machine rotative ; une unité de mesure permettant de mesurer la taille d'un bain de fusion lorsque le soudage est effectué par l'unité de soudage ; et une unité de détermination permettant de déterminer la présence/l'absence d'un défaut de soudure sur la base d'une valeur seuil prédéterminée et d'une valeur de mesure réelle comportant la taille du bain de fusion mesurée par l'unité de mesure, la valeur seuil étant déterminée en fonction de l'angle circonférentiel de l'élément à souder qui a été amené à tourner.
(JA) 溶接の欠陥の有無を確実に判定するシステムを提供することを目的とする。 本発明に係る溶接システムは、溶接対象部材を回転する回転機と、前記回転機により回転した溶接対象部材を溶接する溶接部と、前記溶接部により溶接中の溶融池のサイズを計測する計測部と、前記計測部により計測した溶融池のサイズを含む実測値と、予め決められた閾値に基づき溶接の欠陥の有無を判定する判定部とを有し、前記閾値は、回転した溶接対象部材の周方向角度に応じて定められる。
