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:What is the difference between THJ506 welding rod and THJ422 electrode?: The difference between the use of THJ506 electrodes and THJ422 electrodes is that:506 for the strength grade 50 kg grade steel welding. It can be used as AC and DC, but it is better to use DC welder422 for the strength grade 40 kg grade steel welding. AC and DC are available.

Q:Why should the welding electrode prevent moisture? What happens if you get soaked by water?: Because if there is no moisture prevention, there will be welding impurities, welding seam, welding defects are not strong, and may affect the strength of base metal

Q:Why should we weld from top to bottom when welding with bar welding?: Reinforced lap welding the weld bead can maintain high strength, after the completion of requirements of weld full, without inclusions or non fusion defects such as welding method generally depends on the position of welding joint, when the flat from left to right or right to left does not matter, as long as we can guarantee the quality.You said from the bottom up welding, welding joint may be placed perpendicular to the direction perpendicular to the ground, when the weld shall be in accordance with the welding operation to welding, because the weld pool and perpendicular to the ground electrode melting molten iron will be under its own gravity falling down, if down from welding that will cover the molten metal in the weld front (i.e., the hot metal lead) base material is not directly heated and melted arc, resulting in incomplete fusion, incomplete welding defects

Q:Why do welding electrodes need heating?: Prevent welding rod from wettingPreheat the cores, enhance electrode weldabilityIt's also a welding processThe electrode (covered electrode) welding or welding filler metal in melting joint welding of the workpiece.The electrode (coveredelectrode), is the metal coating in the welding core (coating), uniform centripetal pressure applied to core. The core metal cored electrode, in order to ensure the quality and performance of the weld, there are strict rules on the contents of metal elements in the core, especially for harmful impurities (such as sulfur, phosphorus content, etc.) should be strictly restricted, better than the base metal.

Q:What welding Q235 and 16 steel, please enlighten Masters: If you do not answer the question, the general carbon steel electrode will do, such as J422, J506, and so on, and so on, what you have on hand;If you need a large amount of business, choose a cheaper one;If you answer the questions on the book, use E40, typically J422.

Q:When 507560 electrodes are used at the same time, which electrode should be selected?: Should be 506 electrodes bar, J507 is DC alkaline welding rod, and J506 is AC and DC dual basic electrode.Their selection depends mainly on the welding properties, if welding welding seam is important, the general should use J507 electrode; if the weld is not high, is connected to weld, then select the J506 electrode.In addition, if only the AC power supply, you can only choose J506 electrode.In short, under normal circumstances, the basic electrode should try to choose the DC power supply electrode, because it tends to be less than the gas and DC welding electrode.

Q:What are the welding electrodes?: Not a single electrode metal material, which is composed of a metal core and coating. The electrodes of each model are different in composition.

Q:Welding method of 506 electrode: 506 is AC and DC electrode, but it is better to use dc. With AC welding machine, the no-load voltage can not be too low, otherwise it is easy to stick the strip.

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's the type of electrode used for 304 stainless steel?: 304 stainless steel is the United States brand, equivalent to the domestic brand 06Cr19Ni10, usually with A102 or A107 welding rod.The selection of reference electrode parent material, selection and composition of base metal electrode in the same or similar; owing to the great influence of carbon content on corrosion resistance of stainless steel, stainless steel weld metal carbon content is higher than that of base material. A102 is Cr19Ni10 stainless steel electrode titanium calcium type coating, corrosion resistance of the deposited metal has good mechanical properties and resistance to intergranular, has excellent welding performance and anti porosity property, anti cracking, red medicine Pinai. A107 is a Cr19Ni10 stainless steel electrode with alkaline coating. The deposited metal has good mechanical properties and intergranular corrosion resistance. Therefore, they are aimed at 304 development of welding electrodes.
