Re: [MW:35903] Black Spots on DSS Welding

Dear Mr. Mahmood, Please advise your welder , before welding, take a piece of emery paper and rub the entire surface of TIG wire then start welding. Please proceed with Pickling and passivation after this.

Re: [MW:35867] 347H material weldability

Hi Zakaria, Hope it is piping material and generally we use GTAW + SMAW welding processes to weld such stabilized grade material. For SS347H material, the recommended welding consumables are AWS ER347 for Gas Tungsten Arc Welding (GTAW) and AWS E347 for Shielded Metal Arc Welding (SMAW) . Please check your customer's specifications for PWHT and other requirements. Being stabilized grade PWHT is recommended at 900 deg. cent. temperature for 4 hours.
