IMIYALELO:
1.Ama-electrode kumele abhakwe ngaphansi kuka-350-400℃ ihora ngaphambi kokushisela, afakwe ethini lokuvala futhi asetshenziswe ngokushesha lapho edingeka.
2. Amabala okushisela njengokugqwala kufanele asuswe, futhi i-weld kufanele ishiswe ngaphambili ibe ngu-200 ℃.
I-3.Weld ingafakwa ngaphansi kuka-600-650 ℃ ngemva kokushisela ukuze kuqedwe ukucindezeleka kwangaphakathi.
