Protective atmosphere blowing method thlan dan principle .
A hmasa berah chuan a chiang tur chu weld-a 'oxidized' an tih hi hriatthiam awlsam tak a ni. Theory-ah chuan weld-a component thenkhat leh boruak chhunga component awmte chu chemical-in an inrem a, chu chuan weld quality a ti chhe thei a ni. A tlangpui ber chu weld-a metal component active zawk chuan boruakah oxygen, nitrogen, leh hydrogen te nen chemical hmangin temperature engemaw chen chu an inrem thei a ni.
Weld chu 'oxidized' a nih loh nan chutiang active components te chu weld-a metal components te chu temperature sang takah an inzawm loh nan tihtlem emaw ven emaw a ni. Kan hriat vek angin, temperature sang tak hian molecular activities a ti chak zawk thei a ni. He high temperature state hi molten pool metal chauh a ni lo va, weld metal a hmin atanga molten pool metal a solidified a, a temperature chu temperature engemaw chen a tlak thlenga a hun chhung zawng zawng a huam tel bawk.
Entirnan, titanium alloy welding-naah, a lumna 300°C emaw a aia sang emaw a thlen chuan titanium alloy chuan boruakah hydrogen a la lut nghal vat thei a; 450°C aia sang a nih chuan boruakah oxygen a la lut nghal vat ang; 600°C emaw a chunglam a thlen chuan nitrogen chhunga boruak chu rang takin a la lut thei a ni. Chuvangin, titanium alloy weld te chu a solidified a, temperature chu 300 °C aia tlem loah tihhniam a nih hnuah chuan welds complex te chu weld te nena inzawmna atanga isolate turin tha taka venhim a ngai a, chuti lo chuan weld te chu 'oxidized an ni ang.' Molten pool leh base metal inkara inzawmna degree pawh a nghawng ang.
Weld chu temperature bik thlenga tihlum a nih chhunga weld quality tha zawk neih theih nan, . Hangao Tech (Seko Machinery) chuan thil thar siamin, welding section-ah hian atmosphere box a dah belh a, chu chu . High standard welding pipe siamna hmanrua . Welding torch a thawh lai hian boruak atanga chhuah tumna tihhlawhtlin nan flow rate engemaw zat concentration engemaw chen vawng reng turin box chhungah hian invenna boruak a inject nghal a ni. Protective atmosphere tunnel chu cm 30 vel a sei a ni bawk a, chu chu a la awm temperature chu weld oxidize loh nan a ni.
A chunga kan sawi tak atang hian inject tur hian weld pool venhim a ngai mai bakah welding zawh hnua solidified lo area humhalh a ngai tih kan hre thei a, chuvangin a tam zawk chuan side-shaft side blowing protective atmosphere an hmang ang. A chhan chu coaxial protection method nen khaikhin chuan he method hian protection range zau zawk a nei a, a bik takin weld solidified chauh na hmun tan chuan.
Mahse, engineering application atan chuan product zawng zawng hi side-shaft side blowing protective gas hmangin weld theih a ni lo. Special product thenkhat tan chuan shielding gas coaxial blowing method chauh hman theih a ni a, product structure joint form chu target-a thlan a ngai a ni.
Specific protective atmosphere blowing method thlan chhuah .
1) Straight Weld .
A product weld shape chu a dinglam a nih chuan butt joint, lap joint, internal corner joint emaw overlap weld joint emaw a ni thei. Hetiang chi hi side-blow protective atmosphere hman nan a tha zawk.
2) thlawhna khar graphic weld .
A product weld shape chuan flat circle, flat polygon, leh flat polyline ang chi closed shape a rawn pholang a, chu chu joint form a ni a, chu chu butt joint, lap joint, leh overlap weld joint te a ni. Hetiang chi product hian coaxial shielding gas method a hmang a, welding effect pawh a tha zawk ang.
