Electrode storage method	The electrode must be classification, grades, partial deposit. The electrode must be stored in dry and ventilated warehouse. Electrode shall be 0.3 meters from the ground and metope. Remark: pls pay attention to moistureproof .

Q:It's expired. What color is it? It's better to have screenshots: Sure.Welding rod can not be damp, otherwise it will seriously affect weld quality.

Q:Please tell me the current corresponding to various types of welding electrodes in detail!: Sectional area of electrode x15Such as 4mm welding rod, =2x2x3,14x15=180

Q:What's the difference between 507 and 422 electrodes?: 507 is the welding manganese steel material, and the 422 is the general steel, that is, low carbon steel

Q:What's the model of lap welding for two grade steel bars?: Two grade steel lap welding electrode should be in line with the current national standard "carbon steel welding rod" GB/T 5117 E4303

Q:12 chromium vanadium molybdenum with what electrode?: R312 welding rod or welding wire, model is E5503-B2-V,Or R317 electrode or wire, the model is E5515-B2-V.

Q:What is the difference between tin strip and electrode?: Tin bars are welded by welding iron, used in electronic products and welding electrodes, and used in Engineering (for example, construction, shipbuilding).

Q:Why can't manual arc welding be performed with bare electrode?: Please read the role of electrode coating. Medicine skin on the one hand, stable arc, on the one hand protect and + alloy role, there is no drug skin, welding rod can not continue stable combustion, molding is not good, poor quality

Q:What kind of welding rod used for HRB500 steel bars?: E60xx welding rod for HRB500 steel bar.Turn left and turn right |The electrode (coveredelectrode), is the metal coating in the welding core (coating), uniform centripetal pressure applied to core. The core metal cored electrode, in order to ensure the quality and performance of the weld, there are strict rules on the contents of metal elements in the core, especially for harmful impurities (such as sulfur, phosphorus content, etc.) should be strictly restricted, better than the base metal. The electrode consists of two cores and coating composition. The different cores are also different. The core components directly affect the composition and properties of the weld metal, so the harmful elements in the welding core to as little as possible.

Q:Welding Q345C steel plate with ordinary electrode?: Welding Q345C steel plate with ordinary welding rod, that is, 16Mn should use 507, ordinary welding rod welding performance is poor, hope to adopt

Q:How many roots are there in a package of 2.5 electrodes?: Yibailiuqishi root.
