Hot short cracking
WebRetak Dingin atau cold cracking di daerah pengaruh panas atau HAZ umumnya tidak langsung terbentuk saat pengelasan. Retak jenis ini terjadi setelah proses pengelasan selesai, biasanya setelah beberapa menit sampai dua hari atau bahkan bisa lebih lama lagi. Karena retak terjadi setelah pengelasan selesai, maka retak ini disebut retak lambat. … WebAug 5, 2024 · Hot cracking occurs when the available supply of liquid weld metal is insufficient to fill the spaces between solidifying weld metal, which are opened by …

WebIn newer designs, cracking takes place using a very active zeolite-based catalyst in a short-contact time vertical or upward-sloped pipe called the "riser". Pre-heated feed is sprayed into the base of the riser via feed nozzles where it contacts extremely hot fluidized catalyst at 1,230 to 1,400 °F (666 to 760 °C). http://alcotec.com/us/en/education/knowledge/techknowledge/aluminum-filler-alloy-selection.cfm
