Q:What welding rod does 16MnDR use?
16MNDR can use E5015 low temperature welding rod.E5015 low temperature welding rod:Features: low hydrogen and sodium type low temperature steel electrode with nickel, direct reverse welding, all position welding, and welding metal still has good impact toughness at -60 centigrade.Uses: welding -60 degrees, low temperature steel structure, such as 13MnSi63, 09MnNiNb, E36 and so on.Material (deposited metal chemical composition):C Mn 1.2-1.7 = 0.07 Si = 0.5 Ni S = 0.035, P = 0.035, 0.2-1Other: B = 0.003, Ti = 0.03
Q:When welding, for example, 3.2 of the electrode should choose how much current
The current selection depends on the thickness of the steel plate welding you, if it is a few thick milimeter can use 150A 200A to 10 mm thick, can use 180A to 250A.Pu steel plate for large current will be easy to wear thick steel plate welding, welding with small current will not!
Q:One millimeter thick iron direct current welding machine welding 3.2 electrode, need much current?
1, 3.2 electrode obviously thicker; should use less than 2.5 diameter of small welding rod;2 、 welding electrode and current matching empirical parametersWelding rod diameter 1.6, 2, 2.5, 3.2, 4, 5, 5.8Current (A) ranged from 25~4040 to 6050~80100 to 130160~210200 to 270260~300This is the experience of welding current, welding, horizontal welding, overhead welding welding current should be smaller than usual 10% ~ 20%.Exp is the confirmation at the time of the experiment. Therefore, before the formal welding, the welding sample should be taken, and the welding current should be obtained to get a solid and beautiful bead.
Q:What's the model of lap welding for two grade steel bars?
One or two grade steel is HRB335, 335Mpa. if used does not require structural strength or do not require strength and yield strength, can be used J42 electrode. Otherwise, using J50 electrode. Welding for steel structure, general requirements for the strength of weld metal and base metal electrode. According to the strength of the steel structure. Choose the corresponding strength.Two, two simple introduction of steel bar:That is the new standard name for HRB335 steel, two steel for the old, as a kind of hot rolled ribbed bar. Thread steel in the construction industry, the second class of rebar and grade III thread steel is called in the past, the new standard, the second class of rebar is called HRB335, and the third class of rebar is called HRB400. Widely used in housing, bridges, roads and other civil engineering construction.
Q:How much is the electric welder with 4 mm electrode?
250A above welding machine can, and the specific price depends on what type of machine, more than 1500 yuan
Q:There are several welding electrodes in manual arc welding
There are several kinds of welding electrodes for manual arc welding:1, E4303:E means welding rod, 43 means the tensile strength of deposited metal 430MPa, 0, indicating that welding electrode is suitable for metal position welding, 03 means welding current type for AC or DC zone reverse, and the coating is titanium2, E5015, E means welding rod, 50 means the tensile strength of deposited metal 500MPa, 1, indicating that welding electrode applies to all position welding, 15 means that the electrode is low hydrogen sodium type leather, DC reverse.3, J422, J said electrode for structural steel welding rod, 42, said weld metal tensile strength 420MPa, 2, said electrode for titanium calcium type leather, AC and DC positive and negative connection4, J507 and J indicate that the electrode is the structural steel welding rod, and the 50 represents the tensile strength of the weld metal 500MPa, and 7 indicates that the electrode is low hydrogen and sodium type and the skin is directly connected with the reverse.
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:Why not use 422 electrodes and 502 electrodes on the site? (Shanghai Kunming Railway)
J422 welding rod is lower than steel standard. The strength of J502 is the same as that of steel bar, which is the reason of using J502 welding rod.Different reinforcement materials, the electrode tensile strength is not the same. The strength of the steel bar must be the same as that of the steel bar. The strength of the welding rod once, the steel bar will appear the weld organization intensity is low and the crack; the welding rod strength is higher than the steel bar, the welding seam and the reinforcement will have the bigger peeling force, similarly will crack.Model: J422, brand: E4303 belongs to titanium calcium type low carbon structural steel welding rod. It is suitable for low carbon structural steel with welding tensile strength Q235.Model: J502: E5003, belongs to titanium calcium type low alloy structural steel welding rod. Low alloy structural steel suitable for welding tensile strength Q345 grade.
Q:What kind of paint does the red arc welding electrode add inside?
The red arc welding electrode is a special kind of nickel titanium oxidant, which is mainly used for stainless steel welding electrodes.Welding electrode is composed of two parts: core and coating composition. The electrode is coating in metal welding core (coating), uniform centripetal pressure applied to core. The electrode of different types, different cores. 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.
Q:After the remaining number of suitable welding
After we calculate the utilization rate, the remaining 50mm of the welding rod is welded
