Q:After the remaining number of suitable welding
Current magnitude plus experience
Q:How long is the effective period of welding rod?
If the stock period exceeds the prescribed time limit, the electrode, flux and flux cored wire must be re examined before the relevant functional departments can be issued and used. complexTest principle to check whether the welding material may affect the quality defects, generally limited to appearance and process performance test, but there are doubts on the performance of welding materials, can increase the necessary inspection item.The prescribed time limit may be determined by the following method from the date of production:A) the period of recommendation for welding materials, quality certificates or manuals;B) a low hydrogen type welding material for acid welding materials and moisture resistant packages, sealed for two years;C) graphite type welding materials and other welding materials for one year.
Q:How many kinds of welding rod are there? What's the name? What is the use?
There are many kinds, not less than 100 kinds, welding plastic, cast iron, ordinary steel, alloy steel, stainless steel, etc.
Q:What are the requirements of steel structure for electrode?
E43 series welding rod for common steel structure Q235Q345 material of steel to use E50 series welding rodWelding between Q235 and Q345 steels requires the use of E43 series electrodes
Q:What kind of welding rod is Mt -12?
MT-12 is J421 (E4313) - type carbon steel welding rod.Carbon steel electrode (its tensile strength of deposited metal is less than or equal to 500MPa or 50kgf/mm2), suitable for welding carbon steel and low strength low alloy steel.The electrode of low hydrogen type, powder type, welding electrode must be baked above 350 DEG C, as far as possible to do with baking with, how much the drying principle, otherwise it will result in welding defects (such as porosity, cracks, slag, clamping process performance deterioration etc.). The cellulose type welding rod should be baked strictly according to the baking temperature stipulated in the instruction. When the temperature is too high, the cellulose in the coating will be burned and the inherent technological property of the welding rod will be destroyed.When using the low hydrogen electrode, the welder shall be in the upper wind position, strengthen the exhaust air, and prevent the welding fume from damaging the body.For the low hydrogen type welding rod, the number of baking can be less than two times as much as possible, so as to prevent the medicine skin from becoming brittle and falling off.
Q:What are the main differences between automatic submerged arc welding and rod arc welding?
Automatic submerged arc welding is rolled into a circle, usually in the current voltage of 500A~700A in general 27~34 V according to different wire diameter is automatically fixed rail, and automatic wire and flux mechanism do not require high skills, general training ten hours can be operated.Electrode welding, you say is the hand welding, welding rod is about 50CM, generally speaking of the welder skills requirements are relatively high, you can see the basic level of welding machine, is the constant flow characteristics
Q:How are the electrodes made up?
The electrode composition is divided into two parts, metal core and coating (coating). It is composed of manganese, silicon, chromium, nickel, iron alloy, organic substance and so on.Core: generally use low carbon steel as the core, and adding manganese, silicon, chromium, nickel and other ingredients.Coating: Minerals (such as marble, fluorite etc.), iron alloy and metal powder (such as manganese, ferro titanium), organic matter (such as wood powder, starch), chemical products (such as titanium dioxide, water glass, etc.).
Q:Where is the difference between 422 electrode and E50 electrode?
Difference between J422 welding rod and E50 welding rod:The strength of J422 is 420MPA, and the brand is E4303.E50 electrode strength of 50 0MPa, common E50155016, etc., equivalent to J506, J507, J is the electrode brand, Chinese knot Jie (structural steel) of the first spell. The parameters behind the letter include strength, skin, power supplies and so on.E is the electrode type. E refers to the electrode, and the figure in the back is usually 4 figures, indicating 12 strength, 34 welding position and welding current type and type of coating.What is the difference between the type and grade of welding rod?The model containing strips is stipulated by the national standard, and its meanings include the type of the coating, the type of alloy, the strength, the applicable welding power, etc., and the classification is very fine. The brand of welding rod is a relatively common term formulated by manufacturers. Such as electrode model E4303, the corresponding brand is J422
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:Is the electrode of E43 and 422 of electrodes the same?
You buy the electrode is right, you say E43 is GB model, 422 is the manufacturer's brand, you can weld Q235B steel pipe.
