Laser welding-ah chuan eng ang blowing method nge kan thlan theih ang, engtin nge principle of shielding gas kan thlan theih ang?
1) blowing hmanga thil tih dan .
Tunah hian protective gas blowing dan lian ber pahnih a awm a: pakhat chu paraxial side blown protective gas a ni a, Figure 1-a kan hmuh ang hian; A dang chu coaxial protective gas a ni a, Figure 2-a kan hmuh ang hian.
Engtin nge a blowing method pahnih thlan dan hi thil tam tak ngaihtuah chiang tak a ni. A tlangpuiin side blowing protective gas method hman a tha.
2) Blowing method hmanga thlan dan tur principle .
A hmasa berah chuan weld-a 'oxidation' an tih hi hming tlanglawn mai a ni tih chiang taka hriat a ngai a ni. Theory-ah chuan weld leh boruak chhunga thil tha lo awmte inkara chemical reaction hian weld quality a ti chhe tihna a ni. Chemical hmangin boruakah oxygen, nitrogen leh hydrogen te nen an inrem thei a ni.
Weld chu 'oxidized' a nih loh nan chutiang thil ha lo tak takte chu temperature sang taka weld metal nena inzawmna tihtlem emaw pumpelh emaw a ni. Pool metal chu a nghet a, a temperature chu hun bituk chhung zawngin temperature engemaw zat hnuaiah a tlahniam a ni.
Case thlirletna .
Entirnan, titanium alloy welding hian hydrogen chu 300°C aia sang a nih chuan rang takin a la thei a, 450°C aia sang a nih chuan oxygen a hip lut nghal vat thei a, 600°C aia sang a nih chuan nitrogen chu rang takin a hip thei a, chuvangin titanium alloy weld chu a solidified a, temperature chu 300°C-ah a tlahniam a, a hnuaia stage zawng zawng hi a ni a, chutiang a nih loh chuan 'oxidized an ni ang
A chunga sawifiahna atang hian blown shielding gas hian weld pool chu a hun taka humhim a ngai mai bakah, welded leh solidified mai mai tawhna hmun humhim a ngai tih hriatthiam a harsa lo va, chuvangin Figure 1-a paraxial side kan hmuh ang hian a tlangpuiin blow shielding gas hman a ni a, a chhan chu he method-a protection range hi Figure 2-a coaxial protection method aiin a zau zawk a ni, a bik takin a solid-na hmun chu a solid a ni.
Engineering application atan chuan product zawng zawng hian side-shaft side-blown protective gas an hmang thei vek lo. Product bik thenkhat tan chuan coaxial protective gas chauh hman theih a ni. A bik takin, product structure leh joint form atanga hriat chian a ngai a ni. Target thlan a ni.
1. Protective gas blowing dan bik thlan chhuah .
1) line dik tak weld .
Weld seam shape chu a straight a nih chuan joint form chu butt joint, lap joint, female angle joint emaw lap joint emaw a ni thei. Hetiang chi product atan hian side-axis side blowing shielding gas method hman a tha zawk.
2) Plane khar graphic weld .
Weld seam of the product shape chu plane circumference, plane polygon, plane multi-segment line, etc. ang chi closed shape a nih chuan, joint form chu butt joint, lap joint, lap joint, etc. a ni thei a, he type-a product zawng zawng hian coaxial shielding gas an hmang vek a ni. Way a tha zawk.
2. Thutawp .
Shielding gas thlan hian welding siam chhuahna quality, efficiency leh cost a nghawng nghal vek a ni. Mahse, welding material hrang hrang avang hian welding gas thlan pawh hi welding process tak takah chuan a buaithlak hle. Welding materials, welding methods, welding positions leh welding effect mamawh tur atan welding result tha zawk neih theih nan welding test hmangin welding gas tha zawk thlan theih a ni. 1999 chungchangah zawhna i neih chuan. Laser Welding Industrial Tube Rolling leh Forming Machine , hangao (seko) tih a ni. Exchange leh consultation nei turin team te biak theih reng kan ni.
