Re: [MW:7162] Fw: Regarding Electrode Selection

Hardox weld should be used using soft electrodes.(Yield Strength Less than 500N/mm2).If your weld subjested to heavy wear it is recommended to use the hard facing electrode for the cap beads.   Hardox is weldable using the following electrodes.   SMAW - E7018/E7028/E8016   SAW - F7Ax-xx   MIG/MAG - ER70-x   FCAW - E7xT-x   Hardox 400 40mm combined thickness will need 75°C preheat  and the interpass temp should be kept to 150 - 175°C. If preheating is a problem it is possible to weld without preheat using a 309L type electrode or wire, but remember stainless cannot be burned with standard oxy-acetylene.   Thanks & Regards,   (Karthik)     Karthikeyan.S QA/QC Manager Getabec Energy Co.,Ltd. 379,Moo6,Soi8,Nikhomphatana, Rayong-21180, Thailand.
