Q: What welding electrodes are used to weld 304 stainless steel pressure vessels?: 304 is 18-8 austenitic stainless steel, need to use 18-8 electrode, A102 or A107 can

Q: 12 chromium vanadium molybdenum with what electrode?: Do you need domestic or imported ones?

Q: What kinds of welding electrodes are used in the copper tubes for air conditioning? What's the difference?: Two: copper electrode and silver electrode

Q: Why is the electrode almost finished? Each time there is a little left?: You mean the last point is not welding? That's normal, because there is no welding, no welding, it will stick, and if it is not covered with drugs, it is a waste, oh, do not learn to do so,

Q: What welding rod should be used for welding between No. 20 and No. 45 steel?: No. 20 steel and No. 45 steel belong to dissimilar metal welding. Recommended electrode: J506 or J507.Steel No. 20 belongs to low carbon structural steel. It can be made of low alloy structural steel electrode with J422, J426, J427 and other grade strength.No. 45 belongs to medium carbon steel. The strength level of the matched electrode is J555 J556.Can use J50 series grade intensity of basic electrode welding rod, the electrode is lower than 45 steel J55 welding rod one level, higher than 20 steel J42 welding rod one level.Recommendation: J506 (E5016) low hydrogen potassium alloy structural steel welding rod;Or: J507 (E5015) low hydrogen sodium type low alloy structural steel welding rod

Q: 304 can I use A022 welding rod?: Yes, it's a little waste

Q: This question has been answered, but the answer is not consistent with the proposed problem, I want to ask is how long after the use of suitable electrode, can not damage the electrode holder, but also save, thank you!: After we calculate the utilization rate, the remaining 50mm of the welding rod is welded

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: 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 resistance of welding electrode large?I don't know much about welding. I want to know the general resistance of welding electrode. I also want to know the difference between welding and sub arc welding: No, it can be very small!The core of the electrode is made of good conductive material. The solder around the core is a poorly conductive material.Welding is the use of contact resistance between the electrode and the workpiece is larger, so the heat is larger, the solder, cores and workpiece partial melting, achieve the purpose of welding.
