New flux filling device for welding {FILLING APPARATUS OF WELDING NEW FLUX}

The present invention relates to a new flux filling device for welding, and more particularly, to a new flux filling device for automatically supplying the flux to the flux storage tank after the flux is supplied at room temperature and dried.

In general, submerged arc welding involves placing a particulate solvent, or flux, at the junction of two substrates, blocking the atmosphere, and then between the electrode and the substrate in the flux. An arc is generated and welded by the heat, and the flux of the granular granules is piled up on the base material in advance, and a current flowing therein is continuously supplied to perform welding. At this time, the arc is covered by the flux and is not visible from the outside, and the flux blocks the atmosphere to protect during the refining of the weld metal and contributes to the formation of weld beads or slag.

In addition, submerged arc welding has a deep penetration due to the large size and current of the electrodes used, and is widely adopted as a high efficiency joining technique for thick plate structural steel. It is very important to supply the flux according to the welding conditions of the joint. Flux, which is a material, is expensive, and the flux is recovered after welding to remove slag and iron, and then reused to reduce production costs.

An apparatus for supplying and recovering the flux supplied to the submerged arc welding to the joint of the base material is disclosed in Korean Patent Registration No. 10-0313482, "Air Press Flux Automatic Continuous Supply / Recovery Device."
