5.FAQ:

We have organized several common questions for our clients,may help you sincerely: 

①How about your company?

A world class manufacturer & supplier of castings forging in carbon steel and alloy steel,is one of the large-scale professional investment casting production bases in China,consisting of both casting foundry forging and machining factory. Annually more than 8000 tons Precision casting and forging parts are exported to markets in Europe,America and Japan. OEM casting and forging service available according to customer’s requirements.

②How to guarantee the quality of the products?

We have established the international advanced quality management system,every link from raw material to final product we have strict quality test;We resolutely put an end to unqualified products flowing into the market. At the same time, we will provide necessary follow-up service assurance.

③How long can we receive the product after purchase?

In the purchase of product within three working days, We will arrange the factory delivery as soon as possible. The pecific time of receiving is related to the state and position of customers.Commonly 7 to 10 working days can be served.



Q:Can 50Mn2 casting be welded with 507 electrodes?
1, the tensile strength of 50Mn2 (b/MPa): 930.2, welding with 507 electrodes is not possible, the intensity difference is too great.3, you can also choose J807 or J 907.4, welding is quick cooling.
Q:How do you make holes in the steel plate with the welding rod?
Want to use the electrode punch on the plate, must be able to understand the welding technology, welding machine to increase the output voltage of the arc in arc enough force, the following general 10MM board directly to the plate electrode for an empty blow through, must further expand air through the air, how much space with the electrode with the air bypass to empty suitable size, but the steel bottom plate should be suspended, is conducive to the burning capacity of molten iron in air outflow, general electrode blowing, space is too small is not blowing to using electric drill.
Q:What is the difference between A302 stainless steel electrode and A402 stainless steel electrode?
A402 stainless steel welding rod can weld 304 stainless steel, but it is relatively wasteful. 304 stainless steel with A102, A107, A132, A137 and other stainless steel welding electrodes can be welded.A402 stainless steel electrode:A402 is Cr26Ni21 pure austenitic stainless steel electrode with titanium calcium coating, and has good welding performance.Use: for the same type of heat-resistant stainless steel under high temperature welding, can also be used for hardening of the large steel (such as Cr5Mo, Cr9Mo, Cr13, Cr28 etc.) and the welding of dissimilar steel.
Q:What wire and electrode are used for the welding of 0Cr18Ni10Ti stainless steel pipes? Thank you
ER321 welding wire or A132 welding rod
Q:When 507560 electrodes are used at the same time, which electrode should be selected?
507 506 welding preferred 506. No 560 electrodes, this specification, model, brand.Brand: J506, model: E5016 belongs to low hydrogen and potassium alloy structural steel welding rod. AC welder (no-load voltage is not lower than 70V, machine load rate of not less than 60% of rated output current, welding welding not less than 300 Amperes) DC welder (reverse connection wire clamp is connected with the cathode electrode holder is connected with the anode -, +) polarity electrode. Good welding process. Non Q345 class boilers, containers, pipes and other special components; first choice should be J506 welding rod.Brand: J507, model: E5015 belongs to low hydrogen sodium type low alloy structural steel welding rod. The electrode does not contain arc stabilizer. Only reverse polarity welding shall be used. Suitable for welding Q345R, container, steel and other precision parts. Compared with J506, the deposited metal has lower porosity, slag inclusion, crack and so on. It shall not be used without DC welder.
Q:Types of electrodes
Ask me, the welding rod according to the diameter commonly used has 2.5, 3.2, 4. According to the use of ordinary, stainless steel, cast iron, wear-resistant electrode. Among them, the ordinary electrode according to grade 422506 and 502, stainless steel 102, 132, cast iron points 302, 402. Electrode wear is generally used in digging bucket, carbon and some high wear resistant. These are commonly used welding rod, and some special electrode, the amount is very small. Generally speaking, the higher the grade of the electrode, the more expensive the price. Little dragon, what else do you know? Ask me!
Q:What are the diameters of the electrodes?
To see what type of electrode welding, there are many ways, generally manual electric arc welding general is 2.53.24.0 as if it is the argon arc welding 0.81.01.62.53.0, so to ask what the first electrode size, welding method.
Q:I now want to surface hardening of the roll, ready to use J506 welding rod continuous welding roll surface, how much surface hardness can be achieved?
1, J506 can not guarantee that there is no hardness after surfacing. It is recommended to use D047 welding rod.2, J506 is a low hydrogen potassium electrode, it is a kind of basic electrode, can be welded structural steel and typical Q235 steel, the tensile strength of E4315 is much larger relative to the common electrode, so the general welding force or by welding steel structure of dynamic load.3 roll is an important part of a rolling mill on a steel mill. It uses a pair or a set of rolls to roll and crush the steel. It is mainly affected by static and dynamic loads, wear and temperature changes during rolling.
Q:What is the cause of partial magnetic blow?
Equal distances are provided with double ground wires or multiple ground wires.
Q:What's the difference between 422 and 506? What are their respective attributes?
Different skin, 422 belong to the acid welding rod, 506 belong to the basic electrode. The tensile strength is 422 kg per square millimeter, 506 kg 50 per square millimeter, 42.
