Vuam ntawm kub- dov choj steel phaj16qyuav tsum tau ua tib zoo xaiv cov txheej txheem thiab cov txheej txheem tswj xyuas kom ntseeg tau tias qhov sib koom ua ke muaj zog, tawv, thiab tiv thaiv kev tawg -tseem ceeb rau kev nyab xeeb ntawm tus choj. 16q yog qis- alloy siab- lub zog steel (LAHS) nrog zoo weldability, tab sis nws cov vuam yuav tsum hais txog cov teeb meem xws li hydrogen-induced grain resensual, IC. Hauv qab no yog cov txheej txheem vuam ntau thiab cov kev xav tseem ceeb rau 16q choj steel daim hlau:

1. Shielded Hlau Arc Vuam (SMAW) - Kev Taw Qhia Arc Vuam

Txoj Cai: Siv cov flux-coated electrode uas melts los ua ib lub pas dej ua ke, nrog cov flux generating gas thiab slag los tiv thaiv lub weld los ntawm atmospheric paug (oxygen, nitrogen).

 

Qhov zoo:

 

Cov cuab yeej siv yooj yim, hloov tau yooj yim, haum rau ntawm - qhov chaw vuam ntawm cov pob qij txha nyuaj (xws li, choj girders, pob qij txha ntawm cov khoom siv).

Adaptable rau ntau txoj haujlwm (pav, kab rov tav, ntsug, nyiaj siv ua haujlwm).

 

Daim ntawv thov Scenario:

 

Field welding ntawm choj Cheebtsam (piv txwv li, splicing ntawm steel beams, kev twb kev txuas ntawm stiffeners).

Kho welding los yog me me -batch vuam cov hauj lwm.

 

Cov khoom siv vuam:

 

Tsawg-hydrogen hom electrodes (kom tiv thaiv HIC) yog qhov yuav tsum tau ua, xws liE5015-Glos yogE5016-G(GB / T 5117 tus qauv). Cov electrodes no muaj cov txheej txheem flux nrog cov ntsiab lus hydrogen tsawg (tsawg dua lossis sib npaug li 8mL / 100g) thiab zoo toughness.

Electrode ziab: Ua ntej- ziab ntawm 350-400℃rau 1-2 teev, tom qab ntawd muab tso rau hauv qhov cub tuav ntawm 100-150℃kom tsis txhob nqus dej.

 

Key Parameters:

 

Preheating kub: Rau cov phaj siab dua los yog sib npaug rau 25mm tuab los yog nyob rau hauv qis - qhov kub thiab txias (tsawg dua los yog sib npaug rau 0 degree), preheat rau 80-150℃kom txo tau qhov txias thiab tiv thaiv kom txhob txias.

Interpass kub: Khaws ntau dua lossis sib npaug li 150℃(tab sis Tsawg dua lossis sib npaug li 300℃kom tsis txhob muaj cua sov).

Tam sim no: 140-220A (kho raws li txoj kab uas hla electrode, feem ntau 3.2-5.0mm).

2. Submerged Arc Vuam (SAW)

Txoj Cai: Vuam yog ua nyob rau hauv ib txheej ntawm granular flux, uas melts los tsim ib tug tiv thaiv slag thiab roj, thaum ib tug nruam liab qab hlau ua raws li cov muab tub lim hlau.

 

Qhov zoo:

 

High deposition rate (3–10x SMAW), haum rau ntev, ncaj 焊缝 (xws li, longitudinal seams ntawm steel daim hlau, flange-rau-web pob qij txha).

Ruaj khov arc, tsis tshua muaj spatter, thiab zoo weld zoo (cov khoom muaj pes tsawg leeg, tsis muaj qhov tsis xws luag).

 

Daim ntawv thov Scenario:

 

Factory prefabrication ntawm choj Cheebtsam (xws li, welding ntawm tuab daim hlau nyob rau hauv steel girders, loj - cheeb tsam 拼接).

Vuam ntawm nruab nrab - mus rau - cov phaj tuab (Ntau dua lossis sib npaug li 10mm) nrog rau kev ua haujlwm siab.

 

Cov khoom siv vuam:

 

Hlau:H08MnAlos yogH10Mn 2(GB / T 14957 tus qauv) rau qhov zoo sib xws.

Flux: Alkaline flux (piv txwv li, SJ101G los yog SJ301) kom ntseeg tau tias tsis muaj hydrogen, siab toughness, thiab kuj rau porosity. Flux yuav tsum tau qhuav ntawm 300-400℃rau 2 teev ua ntej siv.

 

Key Parameters:

 

Vuam tam sim no: 500-800A; Voltage: 30-40V; ceev: 30-60cm / min (kho raws li phaj thickness).

Preheating: Rau cov phaj siab dua lossis sib npaug ntawm 30mm, preheat rau 100-150 degree.

Tom qab-weld heat treatment (PWHT): xaiv tau rau cov phaj tuab (Ntau dua lossis sib npaug li 50mm) txhawm rau tshem tawm cov kev ntxhov siab uas seem, feem ntau ntawm 600-650℃rau 1-2 teev.

3. Gas Metal Arc Vuam (GMAW) – MIG/MAG Vuam

Txoj Cai: Siv cov hlau txuas txuas ntxiv ua ob qho tib si electrode thiab muab tub lim, nrog cov roj tiv thaiv (CO₂ lossis CO₂-Ar sib tov) los tiv thaiv lub pas dej.

 

Qhov zoo:

 

Kev ua haujlwm siab, zoo nkauj hlaws, thiab haum rau semi- tsis siv neeg lossis tsis siv neeg vuam.

Adaptable rau nyias - mus rau - nruab nrab thickness daim hlau (6–50mm) thiab ntau txoj hauj lwm.
