Q:Stainless steel 2025 is how material, with what electrode?
Carbon steel, stainless steel welding rod
Q:Why is the electrode almost finished? Each time there is a little left?
Normal, the final electrode about 5 centimeters affect the welder's line of sight, and butt welding to hurt, easy to make welding temperature rise accelerated, influence continuous welding
Q:What kind of welding rod needs baking?
The electrode drying conditions of various types of drug skins are as follows (reference value):The baking temperature of acid welding rod is 150~200 1HThe baking temperature of alkaline welding rod is 350~400 1HThe baking temperature of cellulose electrode is 80 DEG C and the temperature is 1.5 ~ 2HThe baking temperature of graphite type electrode is 200 1H
Q:What type of welding rod is needed for the construction of three grade steel bars used in construction?
In the construction industry, the second grade reinforced bar and the third grade steel bar are called in the past (old standard), and the new standard is replaced by the second grade reinforcing bar HRB335 grade steel, and the third grade steel bar is changed into HRB400 grade steel bar.In brief, these two kinds of reinforcing bars have the same points: they belong to ordinary low alloy hot rolled steel bars, all of which belong to ribbed reinforcing bars (commonly known as rebar), and can be used in ordinary reinforced concrete structures.The main differences are: 1. grades of steel are different (chemical composition is different). HRB335 grade steel is 20MnSi (20 MN SI); HRB400 grade steel is 20MnSiV or 20MnSiNb or 20MnTi.2. with different strength, tensile strength and compressive strength design of HRB335 grade steel is 300MPa, tensile strength, compressive strength design of HRB400 grade steel is 360MPa. The tensile strength and compressive strength of the welding rod J422 are 420MPa.3.. Because of the difference of chemical composition and ultimate strength of steel, they are different in toughness, cold bending and fatigue resistance.
Q:How big is the maximum electrode and how big is the minimum electrode?!
According to the size of the electrode core, usually divided into 2, 2.5, 3.2, 4, 5, 6 mm several, the welding current of them were 50 ~ 80A, 100 ~ 130A, 160 ~ 200A 200-300A 300A-400A.
Q:What are the diameters of the electrodes?
The common diameter is 2.5, 3.24 (mm), also has 2mm, 5mm, generally not commonly used, very rare.
Q:What is the price of titanium - calcium welding rod and low hydrogen type electrode?
Titanium calcium electrode is an acid welding electrode, such as the common J422 (E4303), 4 packets per box, 5 kg per package, about 26-28 yuan per package (fine welding rod expensive)Low hydrogen electrode is basic electrode, such as J506 (E5016) belongs to the low hydrogen potassium type, J507 (E5017) belongs to the low hydrogen sodium type. J506 about 36-40 yuan or so.Prices and brands vary from place to place, for reference only.
Q:Please say a bit more detailed, you can weld the boiler's welding rod varieties, models are said...
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:What kind of welding rod does 1Cr13 steel plate use?
1Cr13 read: a chromium thirteen.Brand: G207; G217 (model: E410-15);Brand: A302; A307; A402; A407 (model: E309-16; E309-15; E310-16; E310-15) welding electrodes can be welded to the stainless steel material.Select the electrode diameter according to the thickness of the workpiece.According to the electrode diameter, packing box description, welding position and other factors, select the polarity of welding and welding current size.
Q:What is the corresponding brand number of electrode model E55?
Welding rod model E55 * *, its brand is J55 * *, such as J507.
