Q:Why stainless steel electrode is relatively short?
The stainless steel electrode generally chromium nickel stainless steel core wire, because of resistance, when the electric current passes through the resistor will produce heat, will make the electrode end of drug skin redness, effect of metallurgical properties and processing properties of electrode. Therefore, in order to prevent the electrode material from the heat resistance caused by red skin, stainless steel welding electrode production than ordinary electrode short.
Q:Welding specification whether welding rod needs experiment
Enterprises need: welding rod, welding flux, welding wire must be dry, heat preservation treatment, and need to do some process evaluation, can determine whether the welding rod suitable for such welding, process evaluation is more important.
Q:What are the functions of E506 structural steel welding rod, which material is suitable for processing?
You say E506 structural steel welding rod, the correct welding rod brand should be written in E5016 or J506, the former model, and the latter is the brand.E5016 welding rod is a kind of alkali and direct current welding electrode. It is mainly used for basic welding rod which is not used by DC welding machine and welding with AC welder. The material used is the same as J507, and is used for 16Mn (Q345) grade steel.When welding the electrode, the process performance is worse than that of the acid welding rod, that is, spatter is bigger and weld formation is poor. But the metallurgical properties are better, that is, the anti - parathion of welding rod is harmful, and the welding seam has strong anti - crack ability, so it is used in welding of important welding seam. However, this kind of electrode tends to be larger than the direct current alkaline electrode (E5015 or J507), so it is seldom used in welding seams (e.g. pressure vessels) that require inspection.
Q:What is the current corresponding to various specifications / models for welding electrodes?
Sectional area of electrode x15Such as 4mm welding rod, =2x2x3,14x15=180
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 specification should be used for the three - step steel electroslag pressure welding electrode?
If the level of 32 thread steel bar is HRB335 (original two grade steel bar), E4303 shall be used for bar welding and lap weldingGrade HRB400 (original three grade steel), bar welding, lap welding using E5003Grade HRB335 (original two grade steel), groove welding using E5003Grade HRB400 (original three grade steel), groove welding using E5503
Q:How much is the angle between the horizontal fillet welding, welding and butt welding?
How is caught in the electrode holder do not have much relationship. The key is the angle between the electrode and the workpiece, horizontal fillet welding is quite appropriate at about 45 degrees.
Q:What is the price of titanium - calcium welding rod and low hydrogen type electrode?
Low hydrogen type expensive, different manufacturers, the price is very different
Q:What is bubble welding? What's the difference between a common electrode and an ordinary one?
Now, there are still two people suspected of welding costs?Do not know that science and technology is the primary productive force?!Said the first two welding material, welding wire electrode 8 dollars a kilogram, 6 yuan a kilo, looks cheap electrode.You have to see how much of the filler metal left in the weld after welding is equal to the price.1, the outside of the electrode coating, and finally the welding slag and protective gas, does not belong to the filler metal.2, each electrode has a welding rod head, at least 5 centimeters, have to throw away, does not belong to the filler metal.3, welding rod splash, splash of metal, does not belong to the filler metal.In addition, other costs, welding rod to dry, need oven, heat preservation barrel, heating electricity, throw away the welding rod.Let's talk about the same welding power, welding, welding heat input two is small, costs less power, more power inverter welder.What's more about efficiency and speed?.1, do not bake electrode, save time, minus a manual.2, do not change electrode, also need not from new arc, save time3, do not knock the welding slag off at least a coolie.4, for welding speed, two welding is three times of welding rod. (on this one, a welder can top three, you have to calculate how much money, artificial!)
Q:What is a welding rod?
This is the process of welding is old, not now, is 2 with the welding steel head away, away from the 10~20MM, and then in the 2 sides of the 1 roots (2 with 1 of the state), one side welding requirement is 10D double 5D, help the section area of the reinforcement bars shall not be less than the main bar section 70%, the force is very good, is a waste of trouble long operation time (the weld is 4 times the length of the lap welding) of the good (space space)
