There are many components of electric welding mesh, and here we will introduce one of them, hoping to help you choose the kind you need! Welding rod is a kind of material which is uniformly and centrally applied to the welding core outside the metal welding core. The welding rod is composed of two parts: the welding core and the coating. The welding core is the metal core of the electrode, in order to ensure the quality and performance of the weld, the content of each metal element in the welding core has strict regulations.
To introduce the introduction, application, use method, storage and transportation and use precautions of the electrode. Welding rod structure: portable welding rod, including powder column, tube, sleeve plug. The solder column is formed by pressing metal or metal oxide powder such as high heat agent and additive. Paper tubes are generally used, and metal tubes can also be used for different welding parts and use environments. At the end of the electrode, the plug is the clamping part that matches the sleeve when welding, and the role of preventing the flux from leaking out of the tube.
Galvanized welding mesh is widely used in industrial production, agriculture, engineering construction, transportation, mining and other processing and manufacturing industries. Such as machine equipment protective cover, animal guardrail, potted flower guardrail, window guard, safety exit guardrail, poultry cage, egg basket and home office food industry basket, paper basket and design decoration. Suitable for general engineering building walls, poured concrete, multi-storey buildings, etc., in the thermal insulation system plays an important structural role, in the construction of the hot dip galvanized electric welding grid insulation board placed on the inner side of the wall to be poured concrete, the external thermal insulation board and the wall a live, after the removal of the mold thermal insulation board and the wall into one body.
The coating on the surface of the welding core is called the coating. The cover of the electrode plays a very important role in the welding process. If the bare electrode is used for welding, during the welding process, oxygen and nitrogen in the air will greatly intrude into the molten metal, oxidizing and nitriding metal iron and beneficial elements such as carbon, silicon and manganese to form various oxides and nitrides, and remain in the weld, resulting in slag inclusion or cracks in the weld. The gas in the molten pool may produce a large number of pores in the weld, which can greatly reduce the mechanical properties of the weld and make the weld brittle.
