I've some detik com bola dilemma about welding inspection , my issue is can we implement vaccum box testing in butt weld joint for roof or bottom. ( for Misc tank)
Ø Inspection by radiographic method just isn't essential for roof-plate or bottom-plate welds, for welds joining roof plates to top rated angle, the best angle on the shell plates, shell plates to bottom plates, or appurtenances to tanks.
apakah ada kemungkinan buckling saat pengelasan whole weld? bagaimana cara untuk mencegah buckling saat horisontal full weld?
Peaking Banding menggunakan sweep board lalu ditempelkan di sambungan dinding shell tanki bagian dalam. Peaking untuk arah vertikal sedang bending untuk arah horizontal.
ada pasal nggak dalam API 650 yang get the facts mengatakan untuk menentukan penggunaan annular plate atau langsung base sketch…oh iya apa effectnya klo pada area base kita nggak menggunakan anular plate? Salam

Ø When the resulting thickness is below minimal expected as per hydrostatic check design problems, re-welding is required.

Mohon kiranya structure laporan inspeksi tersebut dapat dikirimkan juga ke email saya sebagai referensi Pak
Iya pak memang tidak saya bikin detil,..dan check out here hanya mencakup pada waktu development saja. Makasih atas sarannya.
6. After finish created up exam weld metallic with Dye Penetrant examination to assure the weld is sweet and no crack.
Plumbness: Diukur dari paling atas sampai bawah tidak boleh melebihi batas toleransi (1/two hundred) dari tinggi tanki dan untuk tiap shell toleransi plumbness tidak boleh melebihi flatness & waviness dalam STD ASTM A6.
Maaf ni agak lama balasnya,..information yang check my source mas Ifan berikan belum komplit jadi agak susah nelaahnya. Berapa tebal plate? Berapa ukuran stiffener angle nya? Materialnya apa? Deformasinya di materials atau di pengelasannya?
9. just after finish weld from out facet check the radius of buckling plate and location all over again working with stiffener and crucial plate
