Abstract
Method and device (2) for monitoring a welding area of an object (14) in connection with welding, which device includes arrangements (3) for reproduction of the welding area, at least one filter (4) arranged in front of or in the reproduction arrangement (3), and an illumination arrangement (5) of the welding area with ultraviolet radiation. The filter (4) consists of a band-pass filter which is adapted for filtering around a wavelength within the ultraviolet wavelength range.
Claims36
A device (2) for monitoring a welding area of an object (14) in connection with welding, said device comprising:
- means for reproducing (3) the welding area;
- at least one filter (4) arranged in front of or in the reproduction means (3);
- means for illuminating (5) the welding area with ultraviolet radiation;
- and
- said filter (4) comprising a band-pass filter configured for filtering around a wavelength within the ultraviolet wavelength range.
An arrangement (1) for controlling a welding operation, said arrangement comprising:
- a device (2) for monitoring a welding area of an object (14) in connection with welding, said device comprising:
- means for reproducing (3) the welding area;
- at least one filter (4) arranged in front of or in the reproduction means (3);
- means for illuminating (5) the welding area with ultraviolet radiation;
- and
- said filter (4) comprising a band-pass filter configured for filtering around a wavelength within the ultraviolet wavelength range;
- means (9) for processing an image produced by the reproduction means (3);
- and
- means (10) for controlling one of:
- at least one welding parameter and the position of the welding head (11) of the welding means (7) on the basis of information from the image.
A method for monitoring a welding area of an object (14) in connection with a welding process, said method comprising:
- illuminating the welding area with ultraviolet radiation;
- reproducing the welding area;
- and
- filtering radiation from the welding area in a direction toward a means (3) for said reproduction, said filtering being carried out using a band-pass filter (4) around a wavelength within the ultraviolet wavelength range.
A computer program comprising computer program segments that implement a method, when the program is run on a computer, for monitoring a welding area of an object (14) in connection with a welding process, said method comprising:
- illuminating the welding area with ultraviolet radiation;
- reproducing the welding area;
- and filtering radiation from the welding area in a direction toward a means (3) for said reproduction, said filtering being carried out using a band-pass filter (4) around a wavelength within the ultraviolet wavelength range.
A computer program product comprising computer program segments stored on a computer-readable means that implement a method, when the program is run on a computer, for monitoring a welding area of an object (14) in connection with a welding process, said method comprising:
- illuminating the welding area with ultraviolet radiation;
- reproducing the welding area;
- and filtering radiation from the welding area in a direction toward a means (3) for said reproduction, said filtering being carried out using a band-pass filter (4) around a wavelength within the ultraviolet wavelength range.
