What welding electrodes are used to weld 304 stainless steel pressure vessels?
304 is 18-8 austenitic stainless steel, need to use 18-8 electrode, A102 or A107 can
Yes, austenitic stainless steel welding electrode according to the parent metal workpiece to select the parent material and the electrode selection if you are consistent, can withstand the pressure of the weld parent can withstand the same worry.
1, 304 is the United States standard, GB is 0Cr19Ni9, you can choose A102, A107 can, if you don't worry, you can use A302, but the cost is higher, it is better to use A107 welding rod, it's crack performance is better.2, I wish you success.
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
