Anonymous users2024-02-08I don't think you're talking about the HRB400 and not the HBR.
Secondly, I searched on the Internet, E5003 for strip welding and lap welding, and E5503 for break welding and weld groove strip welding.

Anonymous users2024-02-06Dear, hello, I am glad to answer for you what type of electrode is used for HRB400 steel bar is J502 electrode, when there are higher requirements, you can also choose J506 or J507 welding cover strip with good crack resistance. If it is a steel bar for seismic structures, and there is an E after the steel bar grade, it is necessary to use J506 or J507 welding rods. HRB400 rebar is recommended to use:
J422 welding rod in the construction industry, grade steel bar and grade steel bar is the name of the past (old standard), the new standard intermediate steel bar is renamed HRB335 grade steel bar, grade steel bar is renamed HRB400 grade steel bar.

Anonymous users2024-02-05The national standard HRB400 steel is called the trembling ribs, and the corresponding welding rod is matched according to the joint form of different welding positions.
Joint form: rod welding, lap welding electrode type E5003;
Lap welding of steel bars and steel plates, T-shaped fillet welding of embedded parts, model E5003 welding rod;
Groove welding, fused groove bar welding, embedded parts perforated plug welding with model E5503 electrode;
Narrow gap welding with model E6015, E6016 electrode.
The minimum use of J502 electrode, when there are higher requirements, you can also choose J506 or J507 electrode with good crack resistance. If it is a steel bar for seismic structures, if there is an E after the steel bar number, it is necessary to use J506 or J507 welding rod.
For details, please refer to Note 3 under the table of Specification JGJ 18-2012 "Steel Welding and Acceptance Regulations".

Anonymous users2024-02-03What electrode is used to weld HRB400E rebar.
Hello, we are happy to answer for you, HRB400E rebar is generally welded with carbon steel electrodes. The specific selection of the type and specification of the welding rod needs to be determined according to the specific welding requirements. Generally speaking, when selecting welding rods, it is necessary to consider the welding material, welding position, welding thickness and other factors, and use slag to ensure that the welding quality and strength are as required as reed.
It is advisable to carry out a welding test before welding to determine the best welding parameters and welding method.

Anonymous users2024-02-02HRB400 rebar is recommended to use: J422 welding rod.
In the construction industry, grade steel bar and grade steel bar are the names of the past (old standard), the new standard intermediate steel bar is renamed HRB335 grade steel bar, and grade steel bar is renamed HRB400 grade steel bar.
To put it simply, the similarities between these two types of steel bars are: they both belong to ordinary low-alloy hot-rolled steel bars; All belong to ribbed steel bars (that is, commonly known as threaded steel bars); It can be used in ordinary reinforced concrete structure engineering.
The main differences are:
Different steel grades, (different chemical compositions). HRB335 grade steel bar is 20mnsi (20 manganese silicon); HRB400 grade steel bars are 20Mnsiv or 20Mnsinb or 20MnTi etc.
The tensile and compressive design strength of HRB335 steel bar is 300MPa, and the tensile and compressive design strength of HRB400 steel bar is 360MPa. The tensile and compressive design strength of electrode J422 is 420MPa
Due to the difference in the chemical composition and ultimate strength of the steel bar, it also has different properties such as toughness, cold bending, and fatigue resistance.

Commonly known as standard liquid, now when you buy an instrument, the general manufacturer will come standard with two packs of powdered Dongdong, one package is marked on it; And the other pack is marked, (some come with three packs, yes), which requires you to dilute it, if you are at home, you can dilute it with the purified water you drink, one pack can only be mixed with 250 ml of pure water, shake it until it is fully dissolved, (three packs should be divided into three bottles), if you need to use them many times, put them in a container with a lid, and pour a little bit like a disposable cup to soak the head of the electrode when you use it, and the rest will be covered and set aside. This time you should discard the standard solution so that the remaining standard will not become cloudy.
