Q:What's the difference between 506 electrode and 502 electrode?
Agree with wangjun7307's point of view.
Q:Why should the electrode be baked before use?
I don't want to tell you anything that is very theoretical and very textbook. Our project is very wet in the south, so the steel production base often does.The main reason for baking the electrode is (or to prevent) the welding rod from being wetted.Welding rod after wetting, in the welding of workers will indirectly cause more slag, more bubbles, the current is not good control, burn the main tendons, and the strength of the steel bar connection will not meet the design requirements.That's all.
Q:What electrodes can be used to weld boilers?
Welding furnace electrode is the most commonly used J422 and J507 two.Because often used in boiler manufacture, commonly used steel is: sheet --Q245R (20g) and Q345R (16Mng)Profiles --20# (GB3087) tubing 20# (GB699)Among them, the electrode matching Q345R (16Mng) is J507, and the other three kinds of materials match with J422 electrode.
Q:Why is the hydrogen content in the weld lower than that of the alternating current when the acid electrode is welded by direct current?
The welding process is all on the increase of hydrogen from hydrogen weld, welding material, workpiece oil rust and water vapor in the air, so the general basic low hydrogen welding welding before drying;When AC welding of basic electrode, the arc is unstable, and the DC reverse connection is more stable than the direct current connection. Therefore, the welding torch is low and the welding arc is relatively stable;DC electric arc welding, welding welder with positive output, torch (holder) cathode is connected with the output end of the wiring method, called "connect law" also known as positive;DC electric arc welding, welding welder with negative output, torch (holder) connection is connected with the output end of the cathode, called "reverse method" is also known as reverse polarity.When welding with a DC arc welding machine, the welding heat obtained by the direct welding method is high.In the MIG welding, weld reverse DC deep shallow, weld and weld pool is flat, is conducive to the gas pool in the liquid metal, and the arc than is then stable, the protective effect of welding material of gas production slag is better.
Q: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 (%)
Q:What welding rod are used for welding of 304 stainless steel pipes?
Welding rod, A102If welding wire, H08Cr21Ni10Si
Q:Advantages and disadvantages of titanium calcium electrode
Titanium calcium electrode belongs to J422 (E4303). It has good process, stable arc, beautiful welding seam, but low impact toughness and strength. It is not suitable for welding with high structural performance requirement.J507 low hydrogen type basic welding rod, basically contrary to J422. The process is bad, the arc is unstable, only the direct reverse welding and short arc welding can be used. However, because of the strong hydrogen removal ability, hydrogen cracking and defects are not produced, and the impact toughness is high, which is suitable for welding with high structural performance requirements.
Q:Can A102 welding rod weld 316L?
What's the best, A022?
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)
Q:T107 purple copper electrode welding with what
Answer: We specialize in the production of welding machine.Hand welding DC welder.
