Q: What welding wire and electrode are used when welding 16MnD and 16Mn?: J507 (direct current reverse connection)J506 (AC & DC dual purpose)Either of these two is ok.

Q: Which kind of welding wire is needed for the welding of No. 20 steel and 316L?: 316, mainly corrosion resistant stainless steel, so the weld must meet the performance of 316 materials, it is recommended to use ER 316 L welding wire.

Q: ZG40Mn how to weld 70 wire that I use, preheat before welding, keep warm after welding, still appear crack: 1 、 WE600 welding rod or welding wire can be used.2, WE600 alloy steel electrode is a suitable tool and die welding, high-speed tool steel, hot work tool steel, steel, cast steel, T-1 steel, steel, vanadium steel, seismic spring steel, steel, and a variety of unknown type of special welding of dissimilar steel materials, the main feature is the wide universality, high strength matching, high crack resistance, used for special metal and steel maintenance repair places unknown.3, also known as welding: welding, melt, is a kind of heating, high temperature or high pressure way of metal or other thermoplastic materials such as plastic manufacturing process and technology.

Q: What welding wire do 15CrMo and 1Cr5Mo use?: 1cr5Mo and 15CrMo are welded with R207, R307, R407, R317 or A407 electrodes (according to the welding procedures for petrochemical heterogeneous steels, SHT, 3526-2004>>). 1cr5Mo is a class five material, 15CrMo is the four kind of material.The basic principle of electrode selection: there are many kinds of electrodes, each of which has certain characteristics and uses. In order to ensure product quality, improve production efficiency and reduce production costs, the electrode must be selected correctly. In the actual selection of electrode, in addition to considering the economy, construction conditions, welding efficiency and labor conditions, we should also consider the following principles:Principle of equal strength: for the workpiece or structure which is subjected to static load or general load, the welding rod is usually chosen according to the principle of strong welding and base material, that is, the tensile strength of welding seam is equal or close to that of base metal.Principle of equal condition: the welding rod is selected according to the working conditions and characteristics of the workpiece or welding structure. For example, when welding is subject to dynamic load or impact load, the basic electrode with higher impact toughness should be chosen, but the welding electrode can be used in the welding structure.Principle of equality: welding structures under special conditions, such as corrosion resistance, high temperature or low temperature, etc., in order to guarantee the performance, the welding rod shall be selected according to the same or similar principle of the deposited metal and the base metal.

Q: Two welding machine, 1 of the welding wire into 1.2 of the need to change where?: Replace the torch head with a matching pair. Do not change the other, or adjust the current properly.

Q: Loose summer welding machine two, welding 0.8 wire current and voltage how to adjust?: The welding parameters chungha two welding wire welding machine 0.8: welding voltage 17V~19V, welding current 85A~125A, inductance 0.01mH~0.08mH and carbon dioxide gas flow 6L~12L minutes and arc length 8 mm ~10 mm, straight line, Zuo Xianghan welding.The welding parameters according to the different position of welding, spot welding, arc welding arc breaking even thickness of base material, personal habits such as the use of specific welding and welding speed can be relatively large, welding current and welding voltage, beginners should choose the welding parameters of lower and lower welding speed, otherwise it will the welding speed is not uniform, directly affects the quality of welding.0.8 mm wire can be used as push wire welding, also can be used for wire drawing type welding torch. The transition form adopts short circuiting particle transition, and can be welded in all positions.

Q: 2.4, arc welding of stainless steel wire 308 and 308L difference between large? Can I change it between you and me?!: 308 and 308L wire, in theory, the strength of 308L is slightly lower. But the actual test is not low. Simple structural connections can be interchanged. The difference between 308 and 308L is the amount of carbon contained. The rest are the same. The carbon content of 308L is less than 0.03.308, and the content of carbon is less than 0.08.308L can instead of 308, but not recommended (special weld not allowed)

Q: What type of wire for automatic submerged arc welding of Q345B steel plate?: H08A definitely not, low strength, flux 431, welding wire with 10MnSi

Q: The current will crack...... The welding surface is free of impurities...: Causes of weld joint cracking in argon arc welding at 304:1, no argon or gas leakage will lead to welding when the welding seam cracks, check the use of welding torch leak, do a good job of gas sealing measures.2, and 304 material problems, some small factories to do more impurities, welding process can see impurities, welding can obviously see the middle crack. Choose pure 304 wire, more soft is true. (like a wire), otherwise.3, welding angle is smaller and the workpiece is 45 degrees, so that more easily welding workpiece4, secondly, when welding the workpiece, the welding machine should be preheated first, the temperature is not enough, it is easy to weld cracks and heat preservation after welding.Technique and essentials of double sided welding of argon arc weldingOne side welding double face forming technology is an operation technique with great difficulty in welding electrode. It is necessary to master the operation essentials and techniques to guarantee the welding quality and quality.To arc welding, for example, to master welding arc welding, single-sided welding double-sided forming operation technology, must master the "five main points", specific content: see, listen, accurate, short, control. Should also learn to "Six Skills" specific content: solid, start, transport, arc, joint, closing.

Q: Base metal Q235, thickness 4-30mm, welding wire H08C, T type welding, argon rich gas shielded welding. What is the energy of welding line?: The welding line energy depends on the welding current, welding voltage and welding speed. These are the main ones that you haven't written.The welding current is generally between 200-240 and the voltage is between 22-26, but there are some fine adjustments according to the plate thickness and the welding layer. The welding speed is different according to the size of the welding foot, the welding angle of the general A4 and the welding speed 250-300mm/min.Line energy, remember the formula yourself, 0.8*60*I (current A), *U (voltage V) / 1000V (welding speed mm), unit Kj/mm.
