DAJ61F-40P welding stainless steel ammonia stop valve _ welding stainless steel liquid ammonia stop valve _ welding stainless steel ammonia stop valve Before welding, the foreign matter in the pipeline must be thoroughly cleaned, repeatedly confirm whether there is foreign matter in the pipeline, and then install and weld. Before welding, please determine appropriate conditions according to the material of ammonia stop valve, welding rod, current, etc. before operation. Do not heat the valve body too much during welding to prevent deformation of the valve body. Keep the valve open during welding and use clean shielding gas for shielded welding.
