(1) Clean up the contaminations on the steel.
(2) Dry the electrodes at 350~400°C for 60 minutes before welding.
(3) Keep arc as short as possible. Take the back step method to prevent porosity at arc start and re-start. (Please refer to Appendix A)
(4) Preheat and interpass temperature: 177~232°C, PWHT: 725~755°C.
