|||||||||||||
|
(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: 160~190°C, PWHT: 675~705°C.
