〈産業上の利用分野〉
本発明は、溶接前に溶接部を加熱する予熱装置に関する
ものである。DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a preheating device for heating a welding part before welding.
〈従来の技術〉
溶接前に溶接部を予め加熱させる予熱は、溶接部の冷却

部が適度に加熱されるようにしている。FIG. 4 shows a preheating device for performing such preheating on a welding member. The preheating device shown in the figure is used for preheating and welding at approximately equal intervals. Its configuration consists of fixed surface plate 5
2, support columns 54 are installed at equal intervals, a panel material 56 which is a member to be welded is placed on the upper end of this support column 54, and a reinforcing material 5 to be welded to this panel material 56 is placed on this panel material 56.
8 is placed at a predetermined position, and a preheating burner 60 is placed directly below the reinforcing material 58. Then, the weld v162 for welding the reinforcing material 58 and the panel material 56 is moved on the panel material 56 along the reinforcing material 5 (in other words, in the direction perpendicular to the drawing), and in synchronization with this, the preheating burner 60 is turned on for the welding. The welding part is made to run ahead of the welding machine 62 so that the welding part is appropriately heated prior to welding.

った。<Problems to be Solved by the Invention> However, in the preheating surface plate 50, since the support columns 54 are fixed on the fixed surface plate 52, the installation interval of the reinforcing material 58 welded to the panel material 56 must be changed as appropriate. In this case, some of these reinforcing materials will be placed directly above the support column 54, and the preheating burner 60 will be placed directly below the reinforcing material 58.
That is, there was a problem in that it could not be installed properly at the welded part.

A running wheel 20 supported by a spring 18 is attached to the lower part of the support column 8. The support columns 8 are provided in a substantially vertical direction at substantially equal distances on both the left and right sides of the running rail 12, and a pair of such support columns 8 are attached at equal intervals in the longitudinal direction of the running rail 12. The running wheel 20 is a wheel rotatably mounted so as to run in any direction, and is provided at the lower end of the support column 8 so as to protrude from the support column 8, so that nothing can be placed on the support column 8. When not in use, the spring 18 protrudes and supports the preheating mechanism 6 so that it can move freely.

させうな距離である。Next, an example of preheating work using the preheating surface plate 2 described above will be described. The preheating mechanism 6 on the fixed surface plate 10 is connected to the traveling rail 1
The preheating burner 16 on the panel member 2 is arranged on the fixed surface plate IO so that the nozzle portion 24 of the preheating burner 16 on the panel member 2 is equal to the set interval of the reinforcing member 30 to be welded to the panel member 4. Once the preheating mechanism 6 is arranged in this way, the panel material 4 is placed on the support column 8, and the reinforcing members 30 are arranged on the panel material 4 at the predetermined intervals. Then, these panel materials 4 and reinforcing materials 30
The spring 18 installed at the bottom of the support column 8 due to the weight of
is compressed, the running wheels 20 are housed, and the support column 8 comes into direct contact with the fixed leg i10. The preheating bar 16 is now placed directly under each reinforcing member 30.
The distance is such that the preheating burner 16 is kept at an appropriate distance and travels at the same speed as the welding device 32 before the self-propelled welding device 32 that welds the panel material 4 and the reinforcing material 30 moves forward. .

場合であっても確実に予熱を行なうことができる。Therefore, according to the preheating surface plate 2 of this embodiment, the preheating burner 1
Since the support column 8 is integrally attached to the traveling rail 12 on which the panel 6 runs, it is configured as a preheating mechanism 6. Therefore, the preheating/heating mechanism 16 is adjusted to the position of the reinforcing material 30 to be welded on the panel material 4.
Even if the reinforcing material 30 is welded at any position on the panel material 4, the preheating burner will not come into contact with the support column attached to the fixed surface plate as seen in the conventional example. Preheating can be performed reliably.
