Mayeso a Hydrostatic
Chitoliro cholimba kuti chipirire mayeso a hydrostatic popanda kutuluka kudzera mu msoko wa weld kapena thupi la chitoliro. Zolumikizira siziyenera kuyesedwa hydrostatic pokhapokha ngati zigawo za chitoliro zomwe zagwiritsidwa ntchito zayesedwa bwino.
Mayeso opindika
Palibe ming'alu yomwe iyenera kuchitika m'gawo lililonse la chidutswa choyesera ndipo palibe kutsegula kwa weld komwe kudzachitike.
Mayeso osalala
Zofunikira zovomerezeka pakuyesa kupendekera ziyenera kukhala:
- Mapaipi a EW D <12.750 mu:
- X60 yokhala ndi T 500in. Sipayenera kukhala kutsegula kwa weld mtunda pakati pa mbale usanafike 66% ya m'mimba mwake woyambirira wakunja. Pa mitundu yonse ndi khoma, 50%.
- Pa chitoliro chokhala ndi D/t > 10, sipadzakhala kutseguka kwa weld mtunda pakati pa mbale usanakwane 30% ya m'mimba mwake woyambirira wakunja.
