Pengelasan bawah air dapat

diklasifikasikan sebagai

1 ) Pengelasan Basah2 ) Pengelasan Kering•

Pengelasan Basah(wet welding)

Pengelasan basah menunjukkan bahwa pengelasandilakukan di bawah air , langsung terkenalingkungan yang basah . Sebuah elektroda khususdigunakan dan pengelasan dilakukan secaramanual hanya sebagai salah satu tidak dalam

pengelasan udara terbuka . Peningkatan kebebasan bergerak membuat wet welding metode yangpaling efektif , efisien dan ekonomis .

Prinsip operasi Welding Basah

Pekerjaan yang akan dilas terhubung ke satu sisi darisirkuit listrik , dan logam elektroda ke sisi lain . Kedua

bagian sirkuit dibawa bersama-sama , dan kemudiandipisahkan sedikit . Lompatan arus listrik kesenjangan danmenyebabkan percikan berkelanjutan ( arc ) , yang mencair

besi kosong , membentuk kolam las. Pada saat yang sama ,ujung elektroda mencair , dan tetesan logam diproyeksikanke dalam melas renang . Selama operasi ini , fluks meliputielektroda meleleh untuk memberikan shielding gas , yangdigunakan untuk menstabilkan kolom busur dan perisailogam transfer. Busur terbakar dalam rongga yangterbentuk di dalam meliputi fluks , yang dirancang untukmembakar lebih lambat dari laras logam elektroda .

Welding hiperbarik ( pengelasan

kering)

Pengelasan hiperbarik dilakukan dalam ruang tertutup sekitar strukturo akan dilas . Ruang ini diisi dengan gas ( biasanya heliummengandung 0,5 bar oksigen ) pada tekanan yang berlaku . Habitatdisegel ke pipa dan diisi dengan campuran bernapas helium danoksigen , pada atau sedikit di atas tekanan ambien di mana pengelasanadalah untuk mengambil tempat . Metode ini menghasilkan sendi las

berkualitas tinggi yang memenuhi X - ray dan persyaratan kode .Tungsten proses pengelasan gas digunakan untuk proses ini . Daerah di

bawah lantai Habitat ini terbuka untuk air. Jadi pengelasan dilakukandalam kering tetapi pada tekanan hidrostatik dari air laut di sekitarnyaHabitat .

RESIKO TERLIBAT

•

Sengatan listrik • Bahaya hidrogen dan oksigen


121/128



Tindakan pencegahan sengatan

listrik•

termasuk mencapai isolasi listrik yang memadaidari peralatan las

• mematikan pasokan listrik segera busurdipadamkan

• membatasi tegangan rangkaian terbuka MMA( SMA ) set pengelasan


122/128



Tindakan pencegahan hidrogen dan

oksigen yang dihasilkan oleh busur• Tindakan pencegahan harus diambil untuk

menghindari penumpukan kantong gas , yang berpotensi meledak . Tindakan pencegahanmeliputi

• penyediaan udara darurat atau pasokan gas ,•

stand-by penyelam ,• dan ruang dekompresi untuk menghindari

nitrogen narcosis mengikuti permukaan yangcepat setelah menyelam saturasi .

Keuntungan Welding Kering1 ) Welder / Keamanan Diver - Welding yang

dilakukan di ruang , kebal terhadap arus laut danhewan laut . Hangat , habitat kering baik diterangidan memiliki sistem kontrol lingkungan sendiri( ECS ) .

2 ) Kualitas Baik lasan - Metode ini memilikikemampuan untuk menghasilkan lasan kualitas

yang sebanding untuk membuka lasan udarakarena air tidak lagi hadir untuk memuaskan lasdan tingkat H2 jauh lebih rendah dari lasan basah.

3 ) Permukaan Monitoring - Bersama persiapan,keselarasan pipa , inspeksi NDT , dll dipantau secara

visual .

4 ) Non-Destructive Testing ( NDT ) - NDT jugadifasilitasi oleh lingkungan habitat kering .

Kerugian Welding Kering

1) pengelasan habitat memerlukan sejumlah besarperalatan yang kompleks dan peralatan pendukung banyak di permukaan . Adalah ruang yang sangatkompleks


125/128



2 ) Biaya pengelasan habitat sangat tinggi danmeningkat dengan kedalaman . Kedalaman kerjamemiliki efek pada pengelasan habitat . Pada

kedalaman lebih besar , busur mengkonstriksi dantegangan yang lebih tinggi sesuai yang diperlukan .Proses ini mahal - biaya $ 80.000 untuk pekerjaan lastunggal. Seseorang tidak dapat menggunakan ruang

yang sama untuk pekerjaan lain , jika itu adalah satu yang berbeda .

Keuntungan Welding Basah1 ) Fleksibilitas dan rendah biaya wet weldingmembuat metode ini sangat diinginkan .

2 ) Manfaat lainnya kecepatan . Dengan mana

operasi dilakukan .

3 ) Hal ini kurang mahal dibandingkan denganpengelasan kering .
