Problems solved by technology

[0006] However, in the recycling and scattering devices described in the above two prior art documents, since the height and width of the recovery and scattering trolley are limited, the overall size of the funnel is also limited.
Therefore, the storage capacity of the flux that can be transported and sprayed at one time by the collection and spraying trolley is also limited.

Embodiment Construction

[0033] Embodiments of the collecting and dispersing device 50 of the present invention will be described in detail with reference to the drawings. However, in the description of the embodiment, the longitudinal direction is a direction parallel to the welding line M of the material E to be welded, and the width direction is a direction perpendicular to the welding line M. Before describing the collecting and scattering device 50, the single-side welding device 1 using the collecting and scattering device 50 will be described.

[0034] "Single-sided welding device configuration"

[0035] Such as figure 1 As shown, the single-side welding device 1 is a welding device for performing single-side welding of the materials E and E to be welded along a welding line M with a welding machine 30 using a flux F. The single-side welding device 1 includes a welding machine 30 , a trolley frame 104 , a welding material conveying and fixing mechanism 105 , a backing device 10 , a support st...

Abstract

The present invention provides a recovery spreading device which is provided with a recovery spreading trolley that is provided with a funnel for storing welding flux. Furthermore the recovery spreading device spreads the welding flux and recycles the welding flux after using. The funnel is provided with the following components: an upper opening which is open upwards, a lower opening which is formed at an inner bottom of the funnel, and an open / close valve which opens and closes the lower opening. The length of the lower opening in a conveying direction is formed to larger than 1 / 5 of the length of the upper opening in the conveying direction. The area of the inner bottom is formed to larger than 20% of the area of the upper opening. According to the structure, large volume of the welding flux can be stored. A large amount of welding flux can be conveyed and can be spread with an appropriate amount.

Description

technical field [0001] The present invention relates to a method for providing pad flux pressed to the back of the welding wire when performing single-sided automatic welding along a temporarily fixed welding wire, and recovering the used flux generated by welding. Recover the dispersing device. Background technique [0002] Generally, steel plates used for ships and the like require a large steel plate area, so they are formed by joining steel plates of a certain size by welding. In the single-side welding device used in the welding work of the steel plate, when arc welding the material to be welded (steel plate to be welded) from one side by the welding machine, in order to form a weld bead on the back surface of the steel plate, Welding wires are welded while pressing the backing flux in the trough to the back of the steel plate with a backing device. [0003] The backing flux, the bottom backing flux laid on the lower layer of the backing flux, and the used backing flu...
