The development of industry has not necessarily reduced the welding method, which has the advantages of small limitation, low cost and permanent connection. The welding rod is the foundation of welding, and the water content of the coating of the welding rod directly determines the welding quality. The welding rod consists of a coating and a core wire, wherein the coating is formed by bonding a plurality of granular substances. The surface area of particles contained in each gram of medicine skin can reach 4000-10000 cm2And water glass as a binder is easily deliquesced. Therefore, when the welding rod is placed outside, water molecules in the air easily enter the coating on the surface of the welding rod, so that the welding rod absorbs moisture. The moisture-absorbing electrode increases the hydrogen content of the molten metal from which it is welded. The increase of the hydrogen content can cause the mechanical toughness of the welding seam to be reduced, and the phenomena of brittle fracture and crack occur, and the welding quality does not reach the standard, which can cause the product to need rework.
In order to avoid the immersion of moisture, the welding rod needs to be placed in the welding rod heat-insulating barrel to be isolated from the outside air. The welding rod used in the traditional welding process has very strict requirements on heat preservation.

Many manufacturers have made a number of improvements to these problems, with some success. But the problems of poor heat preservation effect and large heat loss of the welding rods still exist in the existing welding rod heat preservation barrel. Therefore, the invention discloses the welding rod heat-preserving container which can effectively improve the heat-preserving quality of the welding rod heat-preserving container and reduce the energy consumption and waste at the same time, and is particularly important.
