TIG Welding
Ntshiab helium yog ib qho ntawm feem ntau siv inert gases hauv TIG vuam (Turbidium Arc Vuam). TIG welding yog tus cwj pwm los ntawm kev siv cov roj tiv thaiv thiab kev xav tau kom muaj qee qhov kev sib txuas qhov tob. Cov khoom welded los ntawm TIG feem ntau yog cov hlau nyias, xws li hlau, txhuas, thiab tooj liab. Hauv TIG vuam, ntshiab helium muab kev tiv thaiv muaj zog, tsis txhob muaj teeb meem xws li subcutaneous porosity thiab chipping, yog li ua tiav cov vuam zoo thiab ua haujlwm zoo.
Plasma Vuam
Plasma welding yog qhov siab - lub zog vuam txheej txheem uas siv cov helium ntshiab rau kev tiv thaiv. Plasma vuam tuaj yeem vuam ntau yam hlau xws li hlau, tooj liab, txhuas, tungsten, thiab titanium. Lub peev xwm tiv thaiv ntawm helium ntshiab yog qhov zoo tshaj plaws nyob rau hauv plasma welding, kom ntseeg tau tias thaj chaw weld tsis muaj kab mob los ntawm lwm cov pa roj thiab tshem tawm cov oxides ntawm thaj chaw weld.
Siab -Frequency Induction Vuam
High- zaus induction welding yog txheej txheem vuam uas siv siab - zaus tam sim no los ua kom muaj cua sov hauv thaj chaw vuam, tiv thaiv los ntawm helium ntshiab. High- zaus induction vuam yog tshwj xeeb tshaj yog haum rau vuam stainless hlau thiab chromium alloys, raws li nws cov khoom tiv thaiv tiv thaiv teeb meem xws li porosity thiab oxidation. Ntshiab helium yog ib qho tseem ceeb ntawm high - zaus induction vuam; nws tuav lub inertness ntawm qhov chaw weld thaum lub sij hawm vuam txheej txheem thiab muab kev tiv thaiv zoo heev.
