Claims (16)

1. The brazing control equipment for use with pipe manufacturing machines consists of three main components: a primary component for shaping the workpiece, fed from a roll of metal strip, in the pipe forming process with opposite side surfaces facing each other; a secondary component for applying pressure to the roll to butt the opposite side surfaces of the workpiece together at the weld; and a third component for supplying high-frequency power to the workpiece to braze the opposite side surfaces at the weld point, producing the metal pipe section. The brazing control equipment comprises a camera positioned to provide a visible area, including the weld point, to produce a video signal showing the area illuminated by the pre-arc that occurs within the visible area; an image processor for converting the video signal into a light distribution format; and an interpreter unit for inferring defective brazing conditions based on the light distribution pattern. The interpreter unit also includes a component for generating an alarm signal when the interpreted result indicates a defective brazing condition. 2. The control and management equipment, as referred to in Right 1, which includes a processor containing at least one device for separating the characteristics of the luminous distribution pattern, and which is assumed to include a device for generating alarm signals when the separated characteristics fall outside the acceptable range. 3. Equipment for managing and controlling the bonding process as referred to in Right 2, which will also include components for inferring the causes of defective bonding conditions based on changes in properties that exceed acceptable ranges. 4. The control and integration equipment referred to in right 3, which includes a processor containing components for producing an elliptical area equivalent to the illuminated area, and where the shape properties include one of the areas of the equivalent elliptical area, the length of the major axis of the equivalent elliptical area, the length of the minor axis of the equivalent elliptical area, the position of the center of gravity of the equivalent elliptical area, the length of the circumference of the equivalent elliptical area, and the angle of inclination of the equivalent elliptical area. 5. The control and integration equipment referred to in right 2, where the processor includes components for producing an elliptical area equivalent to the illuminated area, and where the shape properties include one of the areas of the equivalent elliptical area, the length of the major axis of the equivalent elliptical area, the length of the minor axis of the equivalent elliptical area, the position of the center of gravity of the equivalent elliptical area, the length of the circumference of the equivalent elliptical area, and the angle of inclination of the equivalent elliptical area. 6. The control and management equipment, as referred to in Right 1, shall also include a device for comparing the illumination pattern with at least one reference pattern, and a device for controlling a third-order device to adjust the high-frequency power based on the comparison. 7. The brazing control equipment for use with pipe manufacturing machines consists of a primary component for shaping the workpiece, which is fed from a roll of metal strip. This component forms the pipe by aligning the opposite side surfaces. A secondary component applies pressure to the roll, forcing and butting the opposite side surfaces of the workpiece together at the weld point. A third component supplies high-frequency power to the workpiece to braze the opposite side surfaces at the weld point, producing the metal pipe section. The brazing control equipment comprises a camera positioned to provide a visible area, including the weld point, for producing a video signal showing the included image. An illuminated area is generated within the visible area. A shielding mask is placed in front of the camera to partially obscure the visible area, dividing the illuminated area into primary and secondary sections corresponding to each side surface of the workpiece. An image processor converts the video signal into a light distribution format, and an inference unit determines the defective brazing condition based on the light distribution pattern. 8. The control and management equipment, as referred to in right 7, which includes a processor containing components for generating alarm signals when a faulty connection is inferred. 9. The control and coordination equipment referred to in right 8, which the processor includes at least one device for separating the characteristics of the luminous distribution pattern, and which shall, assuming, includes a device for generating alarm signals when the separated characteristics go beyond the acceptable range. 10. Equipment for managing and controlling the welding process as referred to in Right 9, which will also include components for inferring the causes of defective welding conditions based on changes in properties that exceed acceptable ranges. 11. The control and management equipment, as referred to in paragraph 7, shall also include a device for comparing the luminance pattern to at least one reference pattern, and a device for controlling a third-order device to adjust the high-frequency power based on the comparison. 12. The brazing control equipment for use with pipe manufacturing machines consists of a primary component for shaping the workpiece, which is fed from a roll of metal strip. In the pipe forming process, opposite side surfaces are formed. A secondary component applies pressure to the roll, folding and butting the opposite side surfaces of the workpiece at the weld point. A third component supplies high-frequency power to the workpiece to braze the opposite side surfaces at the weld point, producing a metal pipe section. The brazing control equipment comprises a camera positioned to provide a visible area, including the weld point, for producing a video signal showing the included image. An illuminated area is generated within the visible area. A shielding mask is placed in front of the camera. This mask has a transparent window with multiple parallel lines spaced apart in the direction of workpiece movement to divide the visible area into sets of zones. An image processor converts the video signal into a light distribution pattern, and an inference unit determines the defective brazing condition based on the light distribution pattern. 13. Equipment for managing and controlling the connection as referred to in right 12, which the inference unit will include, and equipment for generating alarm signals when the inference results in a defective connection condition. 14. The control and management equipment, as referred to in right 13, which the processor contains at least one device for separating the characteristics of the luminous distribution pattern, and which shall, assuming, includes a device for generating an alarm signal when the separated characteristic goes outside the acceptable range. 15. Equipment for managing and controlling the welding process as referred to in Paragraph 14, which will also include components for inferring the causes of defective welding conditions based on changes in properties that exceed acceptable ranges. 16. The control and management equipment, as referred to in paragraph 12, shall also include a device for comparing the luminance pattern to at least one reference pattern, and a device for controlling a third-order device to adjust the high-frequency power based on the comparison.
