FAQ
- Can plastic welding rod weld PVC?
- It can be welded by heating weldingPVC as long as PVC, PVC is thermoplastic material, and can be welded with plastic welding rod.Can also be used without welding rod direct heating, with ultrasonic welding machine welding.
- 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.
- There are some electrode home models are R312, R317, J507, J422 these are used for what is now know, 2 mantissa is acidic, mantissa 7 is alkaline, I want to know that the four electrode is used to weld what, for example which used for stainless steel, which is used for carbon steel,
- The carbon steel welding rod E represents the welding rod, and the first two figures indicate the minimum value of the tensile strength of the deposited metal. The third position indicates the welding position, and the three or four digit combination represents the type of welding current and the type of the coating.The stainless steel electrode "E" represents the electrode, and "E" is the digital code indicating the chemical composition of the deposited metal. "-" the two digits behind it indicate the type of the coating, the position of the weld and the type of welding current.Specifically, you can see GB5117, GB983.Such as structural steel electrode J422, J is steel structure code, 42 said that the tensile strength of weld metal grade (MPa value 1/10), said at the end of the 2 type of coating and the type of welding power source; and as the austenitic stainless steel electrode, A132, A austenitic stainless steel electrode of the code, the first digit said the main chemical composition of weld metal (Cr, Ni) level consists of second digits, in addition to Cr, Ni other metal components brand variety.The electrode model is based on the mechanical properties of the weld, the type of the coating, the location of welding and the type of welding current. Such as E4315, E is said 43 electrode, said the tensile strength of the deposited metal is minimum, third digits 0 and 1 indicate the position of welding, all position welding, suitable for welding 2 and 4 for horizontal fillet welding, vertical down welding, the last one said the current type and type of coating.
- What is the current of 2,6 electrode?
- About 90-120 of the current
- Can ordinary electrode be used for welding cast iron?
- No way！ Cast iron electrodes must be used! Ordinary welding rod welding porosity is too much, not solid.
- 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.
- What welding electrodes are used to weld 304 stainless steel pressure vessels?
- Please stay here304 of the domestic brand is 0Cr18Ni9, usually with A102 or A107 welding rod, A107 must be DC welding machineA102 stainless steel welding rod features GB E308-16, quite AWS E308-16Description: A102 is a Cr19Ni10 stainless steel electrode with titanium calcium based coating. Deposited metal has good mechanical properties and intergranular corrosion resistance. With excellent welding performance and anti porosity property, anti cracking, red medicine Pinai. AC and DC dual purpose.Purpose: corrosion resistant 0Cr19Ni9 and 0Cr19Ni11Ti stainless steel structures for welding at temperatures less than 300 degrees celsius.A107 stainless steel welding rod conforms to GB E308-15, quite AWS E308-15Description: A107 is an alkaline stainless steel Cr19Ni10 electrode. Deposited metal has good mechanical properties and intergranular corrosion resistance. With DC reverse connection, all position welding can be carried out.Usage: used for welding 0Cr19Ni9 stainless steel structure corrosion resistance temperature is lower than 300 DEG C, also can weld some poor weldability of steel (such as high chromium steel etc.) and welding stainless steel surface layer.Enter your answer, each professional answer will create your authoritative image
- Requirements for welding electrodes for temperature and humidity
- Storage should be kept at 10---25 degrees Celsius and less than 50% relative humidity.
