Definitions
- the invention relates to a method and apparatus for longitudinal seam welding of profile tubes on a process control connected to a plant computer pipe welding system, a directly formed in line from a metal strip in a forming mill slit pipe or formed from at least one metal sheet slotted tube for particular RF welding of the longitudinal seam or the longitudinal seams is supplied, wherein the pipe welding machine is equipped with a means for measuring the temperature of the welding point, which takes effect at the narrowest point, take the rollers by means of a gap with a tapered, V-shaped profile pressed sheet edges of the slot pipe ,
- CONFIRMATION COPY Prospectus describes further applications of pyrometers in the processing or production of hot products, such as in continuous casting, forging, Kokil- lenguss or the like.
- pyrometers In connection with the transport of molten steel in pans the determination of hot spots on the Pfannent. Container outer wall by means of a thermal imaging camera described.
- the pyrometers used in the longitudinal seam welding allow the temperature to be detected, and if this changes, for example, in an HF longitudinal seam tube welding machine, the welding power or the position of the inductor can be adjusted to counteract welding defects.
- the invention has for its object to provide a method and an apparatus of the type mentioned, which can optimize the L jossnahtsch spaung of slot tubes.
- This object is achieved with a method according to the invention in that temperature fluctuations and emigration of the welding point are determined by a directed onto the apex of the converging V-gap with the forming longitudinal seam thermal imaging camera, the continuously measured data processed in the system computer to adjust the welding process be that the welding point with its hottest effectiveness is always in the same position.
- a direct process observation by means of the specifically positioned, arranged at a distance of about 80 cm to the welding area heat camera is thus made for temperature measurement, the thermal imaging camera and the complete environment, eg. B. in a measuring field of 310 x 230 mm, the welding point can see and thus detects an emigration of the welding point.
- the stable measuring data of the thermal imager infrared camera
- Continuous, high-resolution measurement such as 30 frames per minute, simultaneously provides feedback to the operator of the welding machine with on-screen information to the operator.
- the operator will be able to immediately recognize a "cold" weld or receive and correct an error signal, and the measured data can be stored in the computer and evaluated for quality management for the following welding operations, taking into account the respective production conditions, or for quality control or - documented and documented.
- An apparatus in particular for carrying out the method, according to the invention provides that in the pipe welding machine for detecting the welding point a directed onto the area between the welding means thermal imaging camera is arranged. This is provided according to an embodiment of the invention advantageously shielded against circumvention influences on the welding roller frame of the pipe welding machine.
- the thermal imaging camera is positioned and shielded so that it is unaffected by the strong electromagnetic field as well as environmental influences like fog, water or heat.
- the environmental influences can be rendered harmless by, for example, that the upper rollers are formed with emulsion Abweiseschn and / or means are provided which blow away or sucking water vapor or mist, or the slot tube in the welding machine leading rollers, the cooling emulsion of the product in the direction of travel seen fed backward side,
- Figure 1 is a taken in the longitudinal seam pipe welding by a thermal imaging camera with detection of the temperature of the welding point, as a detail, the merging V-gap of a slot pipe with there the (hottest) spot welding reproducing image.
- Fig. 2 shows a schematic representation of a detail of a pipe welding machine a section of the pipe welding machine with a there aligned on the welding point thermal imaging camera, as shown in Fig. 1 in the region of the rear rollers drawn as a large rectangle measuring field.
- a z. B. HF longitudinal seam tube welding machine (with inductive and conductive RF welding), the rolled in the manufacture of longitudinally welded pipes, such as oil or gas pipes for high grades with a diameter in the range of 10 to 40 mm and wall thicknesses up to 4 mm
- Metallb usually comprises a strip preparation, a spiral belt storage, a roll forming or a preforming line, a pipe welding machine and a pipe separator, is shown in Fig. 2 as a simplified, schematic section only the end portion of a pipe welding machine 1.
- V-gap 4th run-in slotted tube 5 shows a partial length of one of successive, provided in HV arrangement vertical and horizontal rollers or rollers 2a and 2b successively transformed from a metal strip, in the pipe welding machine 1 in the product running direction according to arrow 3 increasingly tapered V-gap 4th run-in slotted tube 5.
- V-gap 4 the angle of the tapered V-gap 4 is determined and the course can be entered as measured values in a system computer 7 or the like evaluation.
- the intersection or vertex of the V-gap 4 is located between the rollers or rollers 8 of the welding stand with the local welding means 9. Behind the rollers 8, the finished, longitudinally welded pipe 10 exits.
- a thermal imaging camera 12 shielded against environmental influences is arranged in the pipe welding machine 1. This is aligned in the direction of arrow 13 targeted to the apex of the V-gap 4 and can there on the one hand a larger measuring field 14 and in this the hottest area 15 and in particular also the position of the hottest weld spot 1 detect.
- the continuously measured data are transmitted to the system computer 7 to control the welding process and evaluation of the measured data, which - as also indicated by arrows - with the control panel 16 to display, for example, the closed loop and errors occurring and a database 17 with there for example stored comparison values from the ongoing manufacturing process and / or previous manufacturing processes.
- Fig. 1 is in clear magnification, the measuring field 14 of the thermal imaging camera 12 again, the cooler area 19 dotted weak, the hotter area 20 spotted a bit more strongly and the hottest area 15 in contrast is marked again thicker dotted.
- the registered arrows 18 indicate the direction - forward, backward and upwards and downwards - of the hottest welding spot 11 that is unavoidable during the welding process.
