Q: What is the difference between stainless steel welding wire and electrode?Such as;1, its welding effect or quality?2, how does it affect your body?3, its price and cost profit?The main topic of attention; he influence on the human body, (I once heard that the stainless steel has a great influence on man's reproductive function, welding of stainless steel welding technology do not know now there is no change?): You ask me a question I can't answer it clearly but you improve in this area we know the wire is generally used in the current relatively small range of welding point electrode is large current electrode current so penetrating some plate is too thick to burn in just so I need ordinary things welding welding wire electrode should die more expensive 1 kilograms of dozens of pieces of money is 304 if it is 202 kilogram 20 yuan, a package of electrode also dozens of pieces of money but few will not burn the wire can be used for a long time the two things can't compare you can only know them because they are some things have their own space welding they cannot replace each other?

Q: What are the characteristics of SHJ507 welding rod?: What are the characteristics of SHJ507 welding rod?:SHJ507 is J507, and the SH in front represents only the manufacturer.J507 is a low sodium hydrogen electrode, it is a kind of basic electrode, welding steel structure can be typical of Q235 steel, the tensile strength of E4315 is much larger relative to the common electrode, so the general welding force or under dynamic load of steel structure.J507 welding rod diameter ranging from 2.5mm to 6.0mm, can be carried out in all position welding, welding using DC welder, polarity reversal. Of course, if there is only AC welder in the field, AC welder can be used, but the current needs to be switched on.The weld formation after J507 welding is more difficult than that of the acid welding rod. If an electrode is used on the cover of the steel structure, the acid electrode can be used. Chemical composition of deposited metal (%)J507 component C, Mn, Si, Cr, Mn, P, S tensile strengthPercentage of content 0.12, 0.8-1.4, 0.07, 0.040, 0.035, 490MpaReference current electrode diameter mm, 2.5, 3.2, 4, 6Select current A 70-90, 90-130, 130-150, 150-190

Q: 3.2 how much is a package of bridge electrode: This depends on what kind of electrode, such as J422 welding rod, 3.2mm package is five kg, the price is about twenty yuan. If it is J507 electrode and so on, the price will be higher, such as A132 and other stainless steel prices will be much higher.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.For welding of carbon steel and low alloy steel welding core, are mostly made of low carbon steel as the core, and adding manganese, silicon, chromium, nickel and other components (see wire national standard GB1300 - 77). The reason of low carbon is a low carbon steel wire plastic, wire drawing is relatively easy, on the other hand can reduce the CO content of reducing gas, reduce spatter or porosity and increased weld metal solidification temperature, favorable for overhead welding. The addition of other alloy elements mainly guarantees the comprehensive mechanical properties of the weld, and also has some effect on the welding process performance and the removal of impurities.

Q: How do you know it's a white steel electrode?: Each electrode has a number of general Yilingjisanlingji is white steel 422 is carbon electrode 507 is 506 manganese steel electrode coating structure is just the most common can also see the skin color outside the carbon steel electrode is grey white steel is green and white are easy to distinguish

Q: Why should we weld from top to bottom when welding with bar welding?: Reinforced lap welding the weld bead can maintain high strength, after the completion of requirements of weld full, without inclusions or non fusion defects such as welding method generally depends on the position of welding joint, when the flat from left to right or right to left does not matter, as long as we can guarantee the quality.You said from the bottom up welding, welding joint may be placed perpendicular to the direction perpendicular to the ground, when the weld shall be in accordance with the welding operation to welding, because the weld pool and perpendicular to the ground electrode melting molten iron will be under its own gravity falling down, if down from welding that will cover the molten metal in the weld front (i.e., the hot metal lead) base material is not directly heated and melted arc, resulting in incomplete fusion, incomplete welding defects

Q: When 507560 electrodes are used at the same time, which electrode should be selected?: 1, J506 welding rod, J507 are basic electrode.2, J506 welding rod can be AC and DC dual-use.3, J507 welding rod can only use DC welder.4, if there is no DC welding machine should use J506, if J506 arc difficult, you can consider using J502.5, J507 welding rod crack performance is better than J506.

Q: What kind of welding rod does 1Cr13 steel plate use?: Usually in 1Cr13 and other dissimilar materials welding, choose A302 welding rod, welding should not preheat and after heat, but after welding, it is best to increase heat treatment (of course, no heat treatment is also no problem)It is better to use G202 or G207 if welding of 1Cr13 same kind of material, preheating before welding, heat after welding and heat treatment

Q: What kind of welding rod should be used for welding cast iron? 506?: With 506 is OK, with gas welding is also possible.

Q: How to select welding rod for welding Q245R Q345R?: In the choice, should pay attention to the following points: Q245R and Q345R manual welding can use E5015 J507 welding rod, embedded welding H08MnA welding wire. Carbon wire and low alloy steel welding wire are adopted by welding wire model ER50-6, standard GB/T8110-2008 gas shielded arc welding.
