[0002] The welding rod is composed of two parts: the welding core and the coating. The welding rod is a metal welding core with a coating (coating) evenly and centripetally pressed onto the welding core. Different types of welding rods have different welding cores. The welding core is the metal core of the welding rod. In order to ensure the quality and performance of the weld, there are strict regulations on the content of each metal element in the welding core, especially the content of harmful impurities (such as sulfur, phosphorus, etc.), which should be strictly restricted and better than the parent material. The existing welding rods are subject to many restrictions such as specifications when used. When faced with a seam width exceeding 5CM or a hole, it is difficult to use welding rods to fill it up. It is often necessary to use other materials to graft the product. However, the grafted welded product not only increases the operation steps, but also makes it difficult to ensure the reliability of its materials, and the product is prone to breakage after welding.

[0003] Among them, publication number "CN114571034A" discloses "a welding method for filling holes in iron products using electric welding rods". This welding device provides an idea of ​​setting iron wire as welding rod to increase welding area from the aspect of welding wide seams, and has high practicality. However, this welding device still has certain shortcomings in actual use. Although this welding device increases the welding area by using iron wire, when the iron wire is tied to the cylindrical welding rod, it is easy to slip due to the operating range of the staff, thereby causing the welding operation to be not smooth. For this reason, the utility model provides a welding device for filling holes in wide seams of iron products using welding rods. Utility Model Content

[0023] In this embodiment, the current used by the welding rod 1 when in use is greater than the conventional current according to the specifications of the iron wire 5 .

[0024] Specifically, during use, since the iron wire 5 is wound around the outer side of the drug coating 2 , the current needs to be increased to raise the temperature so that the iron wire 5 can be melted.

[0025] In this embodiment, the fixing sheet 601 is made of plastic.

[0026] Specifically, the excellent properties of the plastic material, such as wear resistance, corrosion resistance, and elasticity, can enable the fixing sheet 601 to be reused during use, thereby reducing the use cost of the fixing component 6 .

[0032] Working principle: During the specific work, the staff holds the welding rod 1, then removes the prepared iron wire 5, and then wraps the iron wire 5 from the welding end 4 of the welding rod 1 to the clamping end 3. When the iron wire 5 is wrapped around the clamping end 4, the staff takes out the fixing plate 601, and clamps the arc groove 602 of the fixing plate 601 to the coating 2 on the outside of the welding rod 1. Then, the iron wire 5 at the end passes through the connecting hole 603 and is wrapped and fixed along the fixing plate 601, so that the iron wire 5 is firmly fixed on the outside of the coating. Then, the processed clamping end of the welding rod 1 is placed on the opposite side of the fastening plate 1202, and then the welding rod 1 is fixed by tightening the hand nut 1203.

After the tightening is completed, the staff holds the handle 8 to start the welding operation. At this point, the use of the welding device for filling wide seams of iron products with welding rods can be completed.
