Pom zoo welding xyaum:

• Sivqis- hydrogen vuam consumables
• Thovpreheating, tshwj xeeb tshaj yog rau cov phaj tuab
• Tswj cov khoom siv hluav taws xob los tiv thaiv HAZ softening lossis dhau hardness
• Tsis txhob siab nruj thaum vuam

 

Hom Welding Challenges:

• Hydrogen-induced cracking txaus ntshai yog tias preheating tsis quav ntsej
• Ua kom muaj kev ntxhov siab ntxiv piv rau qis dua - lub zog steels
• Kev tswj nruj yuav tsum tau ua rau qhov kub thiab txias interpass
• Nrog rau kev npaj kom raug, S890Q ua tau zoo hauvloj welded qauv.

Txiav

Nplaim taws, plasma, thiab laser txiav yog ua tau

HAZ hardness yuav nce tom qab thermal txiav

Ntug sib tsooraug pom zoo rau qaug zog- qhov tseem ceeb

Khoov & sib sau

Siab springback dua li cov qauv steels

Loj qhov tsawg kawg nkaus dabtsi yog khoov radius yuav tsum tau

Kev sib sau txias yog ua tau nrog cov cuab yeej raug thiab tswj cov txheej txheem

Kev pom zoo:

S890Q muajzoo fabrication kam rau uatshaj S960Q, ua rau nws tsim nyog rau cov txheej txheem nyuaj.

S890Q yog siv dav hauvhnyav-tseem ceeb thiab hnyav- thauj daim ntawv thov, suav nrog:

Crane booms thiab crane thav duab

Hnyav siv tshuab

Mining thiab quarry khoom

Offshore thiab marine qauv

Siab -lub zog load- bearing thav duab

Cov choj tshwj xeeb thiab cov qauv hlau

• EN 10025-6 raws li kev tsim khoom
• Ruaj khov Q&T kev kho cua sov
• Dav loj muaj
• Export kev paub nyob rau hauv hnyav engineering tej yaam num
• Kev txhawb nqa rau vuam thiab fabrication

DIN EN 10025 -6 S890Q tsis-alloy structural steel phajyog ib qho pov thawj kev daws teeb meem rau tej yaam num xav tau:

• Muaj zog heev
• Qhov hnyav txo
• Txhim khu toughness
• Tswj kev tsim tus cwj pwm
• Rau cov engineers, nws ua kom muaj kev tsim qauv zoo.
