Kev Tshawb Fawb Txog Kev Siv Tshuab Caster Welding

Dab tsi yog ib qho arc:

pub los ntawm lub zog fais fab ntawm lub caster. Qhov tshwm sim ntawm kev tso pa roj tawm ntawm ob lub ncej hu ua hluav taws xob arc.

Cov roj tiv thaiv yog dab tsi?

Cov roj shielding siv los tiv thaiv cov dej ntws ntawm cov hlau thiab cov pas dej molten los ntawm cov pa phem sab nraud (hydrogen, oxygen, nitrogen) kev nkag mus ntawm cov roj hu ua shielding gas.

Kev siv tshuab vuam caster:

Cov txheej txheem vuam caster npog ntau yam txoj kev vuam caster, cov ntaub ntawv vuam caster, cov txheej txheem vuam caster thiab cov khoom siv vuam caster thiab nws txoj kev xav yooj yim ntawm cov lus dav dav.

Cov txheej txheem vuam caster:

Cov txheej txheem vuam caster yog hais txog cov txheej txheem txheej txheem thiab nws cov kev cai hauv cov txheej txheem vuam caster. Nws suav nrog cov txheej txheem vuam caster, kev npaj ua ntej vuam, kev sib dhos, cov ntaub ntawv vuam caster, cov khoom siv vuam caster, cov txheej txheem vuam caster, kev ua haujlwm vuam caster, cov txheej txheem vuam caster thiab kev kho tom qab vuam.

Txoj kev vuam caster:

Kev sib txhuam yog ib hom kev sib txhuam uas siv cov khoom siv hlau uas muaj qhov kub qis dua li ntawm cov khoom ua haujlwm ua cov khoom siv sib txhuam. Ua kom cov khoom ua haujlwm thiab cov khoom siv sib txhuam kub txog qhov kub siab dua qhov kub ntawm cov khoom siv sib txhuam tab sis qis dua qhov kub ntawm cov khoom ua haujlwm. Siv cov khoom siv sib txhuam ua kua los ua kom cov khoom ua haujlwm ntub, sau cov qhov sib txawv thiab kev sib kis ntawm cov khoom ua haujlwm. Yog li, txoj kev vuam tau ua tiav.

Cov txheej txheem vuam feem ntau yog siv rau cov hlau puag. Feem ntau siv yog arc welding, argon arc welding, CO2 shielded welding, oxygen - acetylene welding, laser welding, hluav taws xob slag pressure welding thiab ntau lwm yam. Tsis tas li ntawd. Cov khoom tsis yog hlau xws li plastics kuj tuaj yeem welded. Muaj ntau txoj kev vuam hlau. Ntau tshaj 40 hom. Muaj peb pawg tseem ceeb: fusion welding, pressure welding thiab brazing.

Kev vuam sib xyaw yog ib txoj kev vuam uas qhov chaw ua haujlwm sib txuas raug cua sov mus rau lub xeev molten. Ib txoj kev ua tiav kev vuam yam tsis siv lub zog siab. Thaum vuam sib xyaw, qhov chaw cua sov sai sai thiab yaj qhov chaw sib txuas ntawm ob qho chaw ua haujlwm uas yuav tsum tau vuam. Kev tsim ntawm lub pas dej molten. Lub pas dej molten txav mus tom ntej nrog qhov chaw cua sov, Tom qab txias, qhov vuam txuas tas mus li raug tsim thiab ob qho chaw ua haujlwm raug koom ua ib qho. Kev vuam siab, ntawm qhov tod tes, yog nyob rau hauv cov xwm txheej siab. ua kom muaj kev sib txuas ntawm ob qho chaw ua haujlwm hauv lub xeev khov kho. Kuj hu ua kev vuam lub xeev khov kho. Cov txheej txheem vuam nias feem ntau yog kev vuam tsis kam, raws li tam sim no hla dhau qhov txuas kawg ntawm ob qho chaw ua haujlwm, qhov twg qhov kub nce vim muaj kev tiv thaiv siab. Thaum cua sov mus rau lub xeev yas, txuas nrog ua ib chav nyob hauv qab lub zog siab axial.

Cov vuam:

Qhov sib koom ua ke thaum lub caster raug welded los txuas ob lub cev sib txuas hu ua weld. Ob sab ntawm qhov weld yuav raug rau qhov kub weld thaum lub sijhawm welding. thaum hloov pauv hauv lub koom haum thiab cov khoom. Thaj chaw no hu ua thaj chaw cuam tshuam los ntawm cua sov.
