Argon a arc halralna chu . Arc welding hmanrua a stable a, a lumna a concentrate a, arc column temperature a sang a, welding production efficiency a sang a, heat-affected zone a tawi a, welded parts te hian stress, deformation leh crack tendency te an nei tlem a Argon arc welding hi open arc welding a ni a, operation a ni a, hmuh a awlsam a; Electrode hloh chu a tlem a, arc sei zawng pawh enkawl a awlsam a, welding lai hian flux emaw coating emaw a awm lo va, chuvangin mechanization leh automation hriat a awlsam a Argon arc welding hian metal zawng zawng deuhthaw a weld thei a, a bik takin refractory metal thenkhat leh awlsam taka oxidized metals, magnesium , titanium, molybdenum, zirconium, aluminum, etc. leh an alloy te Weldment awmna hmun atanga tihkhawtlai a nih avangin all-position welding tih theih a ni. Manual arc welding hmanga pipe weld hian impermeability, slag inclusion, leh pores ang chi defect neih a awlsam hle.
Argon arc welding technique chu stainless steel pipe te tak te te nen a inzawm a, a . Industrial pipe hmanrua chu weldment inkar a gap awm zat tihtlem nan a ni.
1. Thin stainless steel pipe thermal conductivity a tha lo a, direct-a halral pawh a awlsam hle; Welding lai hian welding wire hi fill a ngai tawh lo a, chutiang chuan base material chu direct-a fuse theih a ni.
2. Argon arc welding-a welding thickness range pawh hian practice-ah limitation a nei bawk. 0.5 mm aia tlem a nih chuan argon arc welding hmang suh. Welding wire fill duh chuan welding wire chu a tha tur a ni a, 0.8 mm a ni tur a ni a, current chu a te zawk a, a te tur a ni bawk. Welding wire, 30 A vel, welding machine a danglam a, welding machine hrang hrang angin current size chu a siam tha a ni.
3. Thin-walled pipe tan chuan welding speed a rang tur a ni a, a rang zawk a, a deformation a tlem chuan a tlem zawk a, welding effect a tha zawk a, tui cooling effect a tha zawk bawk. Welding machine pawh a bik takin a awm a, inverter DC welding machine te chu a tlangpuiin thlan a ni a, flow rate pawh a stable hle.
4. Argon thianghlimna, flow rate leh argon flow hun pawh ngaihven a ngai. Argon thianghlimna chu 99.99% aia tam a ni tur a ni. Argon gas hnathawh chu welding process chhunga boruak hmanga molten pool erosion avanga oxidation awm lohna tur a ni ber a, chutih rual chuan weld area chu weld area humhalh nan leh welding performance tihchangtlun nan a tha thei ang bera isolate theih a ni bawk.
5. Tungsten electrode a ni. Tungsten electrode tha tak hian welding effect-ah nghawng pawimawh tak a nei a ni. Tungsten electrode chunglam chu a hrual vek tur a ni a, a tawp pawh a hrual tur a ni a, concentricity tha tak a nei tur a ni. Hetiang method hian high-frequency arc ignition tha tak, arc stability tha tak, deep molten pool, leh stable molten pool a nei a; Weld seam hi a lo insiam tha hle a, welding quality pawh a tha hle. Tungsten electrode chunglam chu a kang chhuak emaw, a chung lamah bawlhhlawh, crack, shrinkage, etc. ang chi defect a awm emaw a ni. Chutiang a nih chuan high-frequency arc ignition a harsa a, arc chu a nghet lo, arc drift, molten pool dispersion, surface expansion, shallow penetration, weld seam poor forming a ni. Chuvangin, stainless steel thin tube chu argon arc welding hmanga weld a nih chuan tungsten quality hi a pawimawh hle.
Stainless steel industrial welded pipe siam chhuah dan chungchanga zawhna i neih chuan zawhfiah theih a ni HAGAO Tech (Seko Machinery) te chu inrawnkhawmna atan hman theih a ni. Kum 20 chuang zet 1999-a siam chhuah kawngah hian kum 2015-a siam chhuah tawhna kan nei tawh a ni.
