Q:What kind of welding rod used for cast steel?
Cast steel can be divided according to the composition of low carbon steel, medium carbon steel, different components of the electrodes used is not the same, if it is a low carbon composition, the common electrode, such as E4303 (J422) on it; if it is steel components, should be used in high strength structural steel electrode, such as E5015 (J507) E5515 (J557), welding welding and preheating, to prevent cracks.
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:What does the number in the welding rod mean?
The number in the welding rod represents the specification, model and content of the electrode
Q:302 which kind of electrode should be used for welding stainless steel with iron?
302 stainless steel watch to cast iron or wrought iron welding.If with iron welding, WE777 welding rod can be used for iron and stainless steel welding, cold welding welding processIf it can be used for wrought iron, steel, including stainless steel and carbon steel, alloy steel and alloy electrode WE600 dissimilar steel welding.
Q:In the pipe welding, a welding rod welding in the replacement of an electrode should be how to deal with joints?
1, if the strict requirements for pipeline welding, portable welder hammer medicine skin clean, in a welding rod arc welding joint has less to stay in the rear has deposited metal (no more than a centimeter can) for a moment, a swing, further the welding slag burn surface welding quality;2, in large long-distance pipeline, welding joints must be cleaned with a sand turbine, and then the next step of welding.
Q:What kind of welding rod is Mt -12?
MT-12 is a kind of low carbon steel welding rod, is Chinese more than 5 Minerals Import & Export Corporation Tianjin branch (hereinafter referred to as Minmetals Tianjin Corporation) brand products, its chemical composition is (%): C 0.09 Mn 0.40 Si 0.20 P 0.019 S 0.015Contrast chemical components, similar to J421, but higher than J421
Q:What kind of welding rod does Q345 steel use?
Weldability of Q345 steelQ345 low alloy high strength structural steel with carbon content of 0.18% ~ 0.20%, tensile strength equal to 470-630MPa. Q345 steel alloy content is less, good weldability, welding generally without preheating.But because the Q345 steel hardened tendency is slightly larger than the low carbon steel, so at low temperatures (such as winter outdoor operations) or welding in high rigidity, large thickness of the structure, in order to prevent the cold crack, need to take measures to preheat. The preheating temperature of 16Mn steel at different plate thickness and different environmental temperature is shown in table 8.Q345 steel welding should be used in E50 type electrode, such as E5015, E5016 for alkaline electrode, the structure is not important, also can choose E5003, E5001 acid electrode. For the weldment with small thickness and narrow groove, E4315 and E4316 welding electrodes can be used.Table 8 preheating temperature of welded Q345 steelThickness of weldment (mm) preheating thermometer at different temperatures (DEG C)More than 16 of not less than of-10 DEG C - C without preheating preheated to 100 to 150 DEG C16 ~ 24 of not less than 5 DEG C 5 DEG C without preheating preheated to 100 to 150 DEG C25~40, not less than 0 degrees Celsius, not preheated, 0 degrees below 100~150 preheating temperatureMore than 40 are preheated 100~150 degreesSubmerged arc welding of Q345 steel H08MnA welding wire with flux HJ431 (open I butt welding wire with flux HJ431) or H10Mn2 (plate groove butt), when the deep groove weld of thick plate welding, welding wire with flux HJ431 H08MnMoA should be used.Q345 steel is the most widely used low alloy steel in our country at present,
Q:What kind of paint does the red arc welding electrode add inside?
The red component is iron oxide. This kind of coating is mainly made of iron oxide and is called iron oxide electrode.
Q:How should welding electrodes be selected?
Q:J807 electrode specification
Gas shielded flux cored wire with high strength steelSHJ807Description: SHJ807 is a metal cored low alloy high strength steel welding wire. When welding, the welding wire is connected to the positive pole and 80%Ar+20%CO2 mixed gas or 100%CO2 is used to protect the welding wire. The welding process has good performance and high welding efficiency. Deposited metal has good crack resistance and high toughness. The workpiece should be preheated in the range of 250~350 centigrade before welding and be treated by tempering at 620 DEG C after welding.Application: it is used for welding high strength steel of relative strength grade, and can also be used for surfacing of ordinary wear-resistant parts or for transition layer of hardfacing parts.Typical chemical composition of deposited metal (%)Ingredients C, Mn, Si, S, P, Cr, MoThe measurement value of 0.065 1.63 0.3 1.05 0.48 0.025 is less than or equal to 0.025Typical mechanical properties of deposited metal: (690 * 1H tempering)Tensile strength (o b) Mpa yield strength (by 0.2) Mpa (5)% elongation impact energy of Akv (-40 C) JMeasured value 8207601838Recommended parameter: (DC+) (1.2mm)Welding current (A), welding voltage (V), dry stretch length (mm), gas flow (l/min)200~260 28~32 15~25 20Matters needing attention:Remove rust, oil stain and moisture before welding.Remove welding slag between welding layers, and avoid slag inclusion.When welding, preheating and post heat treatment are carried out according to process requirements.Welding wire should be kept in a cool and dry place. It can be used up in time.
