Inde, ili ndi kuthekera kowotcherera bwino kwambiri ndipo ndi yoyenera njira zosiyanasiyana zowotcherera, kuphatikizapo MIG, TIG, ndi submerged arc welding.
4 Kodi kusiyana pakati pa mbale yachitsulo ya ASTM A572 ndi A36 ndi kotani?
Chitsulo cha ASTM A572 chili ndi mphamvu zambiri, chimalimbana ndi dzimbiri bwino, komanso chimatha kuwotcherera bwino poyerekeza ndi chitsulo cha carbon cha ASTM A36 chokhazikika, zomwe zimapangitsa kuti chikhale choyenera kwambiri pazida zolemera.
5. Kodi mbale yachitsulo ya ASTM A572 ndi yoyenera kugwiritsidwa ntchito panja?
Inde, ili ndi mphamvu yolimbana ndi dzimbiri ndipo ingagwiritsidwe ntchito panja. Kupaka utoto kapena utoto kungathandize kuti ikhale yolimba.
6. Kodi pali makulidwe ndi kukula kotani komwe kulipo?
Ma plate a ASTM A572 amapezeka m'makulidwe osiyanasiyana, m'lifupi, ndi m'litali, kutengera wopereka. Makulidwe ofanana amayambira pa 3 mm mpaka 200 mm kapena kuposerapo.
7. Kodi mungasankhe bwanji kalasi yoyenera ya mbale yachitsulo ya ASTM A572?
Gwiritsani ntchito Giredi 42 pa ntchito zonse za kapangidwe kake
Giredi 50 ndiyo yomwe imagwiritsidwa ntchito kwambiri pa milatho ndi nyumba zomangira
Magiredi 55, 60, 65 ndi oyenera mapulojekiti olemera kapena amphamvu kwambiri
