DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is to improve welding quality easily by presenting welding results before actual welding.

[0002]

2. Description of the Related Art In recent years, the automation of welding has made remarkable progress, and the variation in welding quality has been reduced and the quality has been improved. However, these advances have made it possible for welding workers with extremely high welding skills to perform actual welding using a large number of sample workpieces to ensure the welding quality required by the designer, and to cut the welded parts. The work of adjusting the welding conditions and the like while confirming the quality has been realized over and over again. In addition, it takes a very long time and labor for a welding operator to have advanced skills.

[0003]

At the welding site, there is a chronic shortage of workers with advanced welding skills. This is due to the aging of workers with advanced welding skills and the fact that it takes a lot of labor and time for new welding workers to learn welding techniques, judge welding results and set welding conditions. As In addition, there is a problem that material and time costs for confirming welding quality are consumed in order to perform actual welding. In order to solve the above problems, it is necessary that the work setting can be made easily and that the quality of the target welding can be easily determined and secured even by a beginner. Therefore, an object of the present invention is to provide an apparatus that can easily determine welding quality before actual welding and sets welding conditions that provide high welding quality in actual welding.

[0004]

Means for Solving the Problems In order to solve the above problems, the present invention relates to an apparatus for displaying a result of welding, comprising: a welding information input section for inputting information on a welding target, welding execution information, welding condition information, and the like. An input information conversion unit that converts information input by the information input unit into welding parameters,
A welding result quantification unit for quantifying the welding result based on the information converted by the input information conversion unit, and a welding result display unit for displaying the welding result information quantified by the welding result quantification unit. The welding information input unit inputs welding information by selecting or writing using at least one of an electric signal, an optical signal, a picture, a numerical value, a character, and a color. The information input by the input unit is used to determine the current, voltage, speed, position,
At least one of posture, material, shape, length, pressure, time, temperature, and energy is converted, and the welding result quantification unit performs welding on each of the information converted by the input information conversion unit. Means for storing a shape as at least one of point information, line information, and surface information; and at least one means for storing in advance a relationship between welding information and welding shape information as a mathematical expression, A welding shape corresponding to the information converted by the input information converting unit is output as numerical information, and the welding result display unit displays the information obtained by the welding result quantifying unit in at least one of a picture, a numerical value, and a character. Is visually displayed. By means of the above means, the operator can input welding target information, welding work information, welding condition information, etc. to the welding information input section and check the welding result in advance on the desk before actual welding. The welding conditions can be determined very easily without the need, and the number of steps for confirming the welding quality by actual welding is drastically reduced, so that material and time costs can be minimized.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention for arc welding will be described with reference to the drawings. FIG. 1 is a block diagram showing the whole of the present invention. Reference numeral 11 denotes welding target information such as a joint shape, a plate thickness, and a gap to be welded; welding execution information such as a welding wire diameter, a wire protrusion length, and a shielding gas; a welding current, a welding voltage, a welding speed, a torch target angle, and a torch. This is a welding information input unit for inputting welding condition information such as a lead angle and a torch target position. Reference numeral 12 denotes an input information conversion unit that encodes (digitizes) information input by the welding information input unit, for example. Reference numeral 13 denotes a welding result quantifying unit that searches the data bank for the corresponding welding shape data based on the data coded by the input information conversion unit, and presents the welding shape data. In the present embodiment, the welding shape data has 40 points of data for one shape using the surface and penetration shape of the welding bead as point information (position information). Reference numeral 14 denotes a welding result display unit that visualizes a welding shape based on the welding data presented by the welding result quantifying unit. In the present embodiment, linear interpolation was performed between 40 pieces of welding shape data. 2 to 6 show application examples of the present invention. 21 is a T-joint in which the web 21a and the flange 21b are arranged in a T-shape. 22 is a welding torch, 23
Is a welding wire which is a consumable electrode, and 24 is a welding bead shape showing a welding result as a shape. FIG. 2 shows the welding information as joint shape: T joint, plate thickness: 6.0 mm, gap:
0.0 mm, welding wire diameter: φ1.2 mm, wire protrusion length: 12.0 mm, shielding gas: Ar 80% + CO
₂ 20%, welding current: 280 A, welding voltage: 26.0
V, welding speed: 40 cm / min, torch target angle 45 De
g, torch advance angle: 5Deg, torch target position: (X,
Y) = (0.0 mm, 0.0 mm) is the welding result (bead shape) displayed when: FIG. 3 shows the welding result when only the welding speed was changed to 30 cm / min and the other conditions were the same as in FIG. In this case, it can be seen that the bead shape is larger than in FIG. FIG. 4 shows the welding result when the welding speed was further reduced to 20 cm / min. From this result, it can be seen that "poor penetration", which is a defect of welding, occurs at the portion 25. FIG. 5 shows that only the target position of the torch is (X, Y) = (− 2.0 mm, 0.0 mm)
It is a welding result when other conditions were made the same as FIG. From this result, it can be seen that "undercut", which is a welding defect, occurs at the portion 26, and "insufficient penetration" occurs at the portion 27. FIG. 6 shows a welding result when the target position of the torch is changed to (X, Y) = (+ 2.0 mm, 0.0 mm) from the conditions of FIG. Under this condition, the undercut and insufficient penetration shown in FIG. 5 are not recognized, and a relatively large bead shape is obtained.

[0006]

As described above, according to the present invention, it is possible to input a joint shape, a plate thickness, a welding current, a welding voltage, a welding speed, a torch position / posture, etc., and carry out actual welding on a desk without performing actual welding. It is possible to easily determine welding conditions for obtaining high-quality welding results without requiring skill. Further, since actual welding is not performed, material and time costs can be significantly reduced.
