Brass tube thiab copper tube txheej txheem sib txawv: rov kho txoj kev kawm ntawm AC thiab DC pulse TIG vuam nyob rau hauv lub nkoj nyias-walled tooj liab raj vuam siv. Los ntawm kev txheeb xyuas ntawm AC thiab DC pulse vuam tam sim no, npaj siv DC pulse TIG vuam vuam hauv qab txheej, AC pulse TIG vuam vuam npog txheej txheej. Qhov kev xaiv ntawm txoj kev no, tsis tsuas yog los xyuas kom meej tias nyias-walled tooj liab yeeb nkab hauv qab txheej weld ib leeg-sided welding ob-sided molding, tab sis kuj los xyuas kom meej tias lub hau txheej weld, tsis yog vim qhov kub ntawm cov txheej hauv qab ntawm qhov vuam qog tshwm sim.
Tom qab welding ntawm nyias-walled tooj liab yeeb nkab weld soj ntsuam, radiographic zaj duab xis qhia tau hais tias cov txheej txheem ntawm welding lub weld zoo qib Ⅰ, mechanical zog thiab metallurgical xeem yog tsim nyog los txhim kho lub vuam zoo ntawm nyias-walled tooj liab yeeb nkab nyob rau hauv lub nkoj cov khoom los muab ib tug siv. Copper yeeb nkab clamping kev sib txuas kev txawj yog los ntawm kev siv cov clamps kom cov yeeb nkab hauv cov yeeb nkab fittings yog clamped ruaj khov, tso siab rau cov yeeb nkab kev txhawb nqa sab nraud siab fittings kawg ntawm U groove sealing nplhaib, tsim kom muaj kev sib txuas mus tas li rau ib qho. kev tsim kho ib zaug, txawm tias los ntawm qhov kev txiav txim ntawm kev tsim kho kev lag luam thiab kev tswj xyuas qhov tseem ceeb thiab lwm yam ntawm cov ntsiab lus muaj cov kev cai nruj dua. Tsab ntawv rau kev siv cov cuab yeej no los ua cov lus qhia ntxaws ntxaws; siv cov thev naus laus zis no thiab kev sib txuas cov kav dej ib txwm muaj rau kev sib piv. Tuam Tshoj lub aerospace, marine thiab lwm yam kev loj hlob sai, tsav los ntawm Tuam Tshoj lub titanium alloys, tooj dag raj nickel-raws li alloys thiab lwm yam zoo hlau xav tau. General titanium, tungsten, npib tsib xee, tantalum thiab lwm yam tseem ceeb thiab nws cov alloys ua ntej xaiv lub tshuab nqus tsev noj nws tus kheej smelting, crucible chim (loj txheem seamless ntshav tooj dag raj) tsim los ntawm centrifugal casting txoj kev, tooj dag raj electrolytic stacking txoj kev, ntim vuam txoj kev, casting + txoj kev ua zes, kneading txoj kev, nyob rau hauv uas lub kneading txoj kev ua tau zoo tshaj plaws.
