Tes Sertifikasi Pengelasan TIG – Tips Untuk Lulus Tes PengelasanTes Sertifikasi Pengelasan TIG – Tips Untuk Lulus Tes Pengelasan

Apa persamaan Boilermakers, Pipefitter, dan Aerospace?

Lulus tes sertifikasi pengelasan visit https://www.advancedweldingschool.com/ TIG biasanya diperlukan untuk dianggap sebagai tukang las yang memenuhi syarat atau bahkan dipekerjakan untuk pekerjaan itu.

Untuk pembuat boiler dan tukang pipa, uji las pipa atau tabung biasanya diperlukan dan dapat berdiameter antara 3/8″ hingga 12 inci dan bergantung pada pekerjaannya, bahan yang dilas biasanya baja karbon atau baja tahan karat, atau baja karbon yang dilas dengan ER309 logam pengisi (kadang-kadang paduan lain dilas tetapi karbon dan stainless membuat sebagian besar tes pengelasan diberikan)

Di sisi lain, tukang las ruang angkasa mungkin diminta untuk mengelas hampir semua logam:

baja karbon / baja paduan rendah – 4130, 4140, 4340, 8630
baja tahan karat – 321, 347, 13-8, 15-7, 17-7, a286
paduan nikel – pelindung x, inconel 718
aluminium – coran A355.356.357, 6061, 2219
magnesium – az31b,
titanium – 6AL4V, CP
kobalt – L605, haynes 188
paduan tahan api seperti columbium
Tes sertifikasi pengelasan tig aerospace umumnya adalah las alur langsung atau las sudut kecuali ketentuan aplikasi khusus dari American Welding Society D17.1 digunakan. Terkadang uji las alur atau sudut sederhana tidak secara akurat mewakili ruang lingkup pengelasan yang dilakukan.

Dalam hal itu ada ketentuan bagi tukang las untuk disertifikasi menggunakan bagian skrap, bagian aktif, atau uji mock up yang mewakili las yang dilakukan dalam produksi. Ini adalah sertifikasi yang lebih terbatas tetapi membantu untuk mengesahkan tukang las pada tugas-tugas yang cukup menguji keahlian yang diperlukan untuk melakukan pekerjaan itu.

Untuk Boilermakers dan pipefitters, tes sertifikasi tig welding pada tabung atau pipa cukup mewakili sambungan yang sama yang dilakukan di lapangan.

Kiat untuk lulus tes pengelasan tig:

pembersihan…berikan banyak perhatian untuk mendapatkan pembersihan yang sempurna dengan memastikan ujung-ujungnya direkatkan dengan rapi dan aman dengan lubang ventilasi di bagian atas agar gas keluar.
Membersihkan logam… Baik mengelas sambungan pipa atau las butt lembaran logam, jika Anda tidak membersihkan logam dengan benar, Anda mungkin akan gagal. Logam seperti aluminium dan titanium rentan terhadap porositas dan pengarsipan tepi menghilangkan kotoran yang akan menyebabkan porositas… Beberapa inspektur pengujian akan mengecewakan Anda di tempat hanya karena tidak membersihkan logam.
Untuk uji las tig kedirgantaraan, pastikan untuk mengikir tepi logam yang terpotong
