Q:What electrode is used on the rails?
The rail steel adopts WE600 welding rod, and the requirement of crack resistance and yield strength is the most ideal.WE600 is a kind of low heat output, suitable for special nickel chromium alloy steel electrode welded all-round, universal design is extremely wide, the general strength of parent materials with high strength, excellent welding performance, stable arc, beautiful shape of seam, in oil, water and rust conditions can welding effect is excellent, can be welded different steel.Suitable for welding of tool and mould, high-speed tool steel, hot work tool steel, steel, cast steel, T-1 steel, Nai Zhengang, vanadium steel, spring steel, martensitic stainless steel, austenitic stainless steel, ferritic stainless steel, and the unknown as well as between the various different types of steel welding etc.. Such as high pressure valves, broken bolt clearance, shaft modification, etc..
Q:J422 electrodes are marked with "THJ422". What does TH represent?
TH: Tianjin Bridge Welding Materials Group Co. Ltd. manufacturer brands. J: stands for structural steel welding rod. 42: two figures indicate that the minimum value of tensile strength of deposited metal is 42kgf/mm2 (412MPa), and the minimum value of the yield strength of deposited metal is 34kgf/mm2 (430MPa). 2: third digit "2" indicates that the type of coating is titanium calcium type, direct current or AC power supply.
Q:What type of welding rod is used for welding 16MnD?
16MnD read as low as sixteen mn. Belong to sixteen Mn low temperature steel.Can useBrand: J507FeNi (model: E5018-G) basic electrode welding.The electrode belongs to a low hydrogen and sodium alloy structure steel powder welding rod. DC reverse connection. All position welding.It has good low temperature impact toughness. Used for welding of medium carbon steel and low temperature steel pressure vessel. Such as:16MnD, 16MnDR, etc..
Q:What is the difference between E4315 welding rod and E5016 electrode?
The main difference between E4315 welding rod and E5016 electrode is that E5016 welding rod is more expensive.E4315: the tensile strength of deposited metal is not less than 420MPa. It is suitable for all position welding, low hydrogen and sodium type, and direct current reverse connection;E5016: the tensile strength of deposited metal is not less than 490MPa. It is suitable for all position welding, low hydrogen and potassium type, AC or DC reverse connection.The chemical composition of both is ordinary low carbon steel, E5016 can be used instead of E4315.
Q:Types of electrodes
Ask me, the welding rod according to the diameter commonly used has 2.5, 3.2, 4. According to the use of ordinary, stainless steel, cast iron, wear-resistant electrode. Among them, the ordinary electrode according to grade 422506 and 502, stainless steel 102, 132, cast iron points 302, 402. Electrode wear is generally used in digging bucket, carbon and some high wear resistant. These are commonly used welding rod, and some special electrode, the amount is very small. Generally speaking, the higher the grade of the electrode, the more expensive the price. Little dragon, what else do you know? Ask me!
Q:What enterprises use more welding electrodes?
Shipyard, boiler plant, steel structure, locomotive, automobile, construction machineryBuilding construction; large building; exterior wall decoration.
Q:Difference between ordinary electrode and tungsten electrode
The common electrode: in the welding process, it is also the weld metal fill electrode, its edge welding edge melting, and to fill in the weld.Tungsten electrodes: non melting electrodes for manual argon arc welding. Or plasma melting non melting electrodes.
Q:What kind of welding rod is used for welding rail and ordinary steel?
It can be welded with J506 and J507. However, if there is a DC welder, it is better to use J507 because weldability is better than J506. Slow cooling after welding.
Q:What is the substance on the outside of the electrode?
The electrode coating consists of various minerals, such as iron alloy, organic substance, water glass and other raw materials.Composition of electrode according to their different functions can be divided into arc stabilizing agent, fluxing agent, gas forming agent, deoxidizing agent and alloy slag agent, dilute agent and binder etc..
Q:What kind of material is the drill pipe and what kind of electrode?
Oil drilling pipe performs API 5DP standardCommonly used steel grade S135, G105, X95, E75. The usual specifications are 60.373, 88.9, 101.6, 114.3127 and so onIt is suggested to use Baosteel brand petroleum drill pipe
