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: How are the electrodes made up?: Answer: welding rod is coated with the skin of the power supply arc welding melting electrode. It is composed of two parts covering and core wire. (L) cores. The electrode is metal cored coating called cores. The core is generally a certain length and diameter of the steel wire. When welding, the welding core has two functions: one is the conduction of the welding current, arc energy converted into heat energy; two welding core melting filler fused with the parent metal weld formation. The special steel wire used for welding can be divided into three categories: carbon structural steel, steel wire, alloy structural steel wire and stainless steel wire. (2) medicine skin. The pressure on the surface of electrode coating called coating. A coating of various minerals, such as minerals, is coated on the outside of the electrode to stabilize the arc and improve the quality of the weld. Some reducing agents should be added into the coating to restore the oxide to ensure the quality of the weld. Because of the high temperature of the arc, some of the alloying elements contained in the weld metal are burned (oxidized or nitrided), which reduces the mechanical properties of the weld. By adding ferrous alloy or pure alloy element to the electrode coating, it can be transferred to the weld metal with the melting of the coating, so as to compensate for the burning of the alloy elements and to improve the mechanical properties of the weld metal. It can improve the welding process performance, make the arc stable combustion, less spatter, good weld formation, easy slag removal and high deposition efficiency. In short, the role of the drug skin is to ensure that the weld metal to obtain the required chemical composition and mechanical properties, and make the welding rod has good welding process performance.

Q: What are the requirements of steel structure for electrode?: E43 series welding rod for common steel structure Q235Q345 material of steel to use E50 series welding rodWelding between Q235 and Q345 steels requires the use of E43 series electrodes

Q: What kind of welding rod used for cast steel?: Layman questions must be answered in large vernacularCast steel can be considered as rolled steel of the same grade.Will the steel rod be selected?

Q: This question has been answered, but the answer is not consistent with the proposed problem, I want to ask is how long after the use of suitable electrode, can not damage the electrode holder, but also save, thank you!: Current magnitude plus experience

Q: Is there any difference between E308 welding rod and 308?: What do you mean by 308? 308 stainless steel? Or Z308 cast iron welding rod? Or something else?

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?: Hardness must be no good, J506 surfacing is no hardness.Now is the use of roller surfacing, preheating, submerged arc welding, after welding heat treatment, machining, welding process to repair. Specific to the surface hardness, different conditions, hardness is also different, but, J506 welding hardness is not achieved.

Q: Why is the welding of important structure using alkaline electrode?: Alkaline is a low hydrogen electrode, which can control the hydrogen content in the weld, avoid hydrogen embrittlement and lead to structural failure. Hydrogen embrittlement is the sudden breaking of the weld force

Q: What kind of welding rod is ECoCr-A?: High temperature wear-resistant alloy electrode, generally used for surfacing

Q: What is the price of titanium - calcium welding rod and low hydrogen type electrode?: Low hydrogen type expensive, different manufacturers, the price is very different

Q: What electrode does Q235 use?: According to the classification of the characteristics of the slag after the electrode is melted, the welding electrode can be divided into an acid welding rod and an alkaline welding rod. The main component of acid electrode coating is acid oxide, such as Q235 low carbon steel. When welding important structural parts, E4315, E4316, E5015 and E5016 should be selected according to different welding conditions.Q235 is a carbon structural steel, which is equivalent to the A3 and C3 steel in the old standard GB700-79, and is used in the Russian TOCT brand. The grade Q represent in yield strength. Normally, the steel is not used directly after heat treatment.
