Hom kev welding:
1. Electrode arc vuam:
Lub hauv paus ntsiab lus: arc vuam txoj kev ntawm vuam nrog phau ntawv vuam pas nrig. Qhov ruaj khov combustion arc tsim nruab nrab ntawm lub vuam pas nrig thiab cov vuam yog siv los yaj lub vuam pas nrig thiab cov vuam kom tau txais kev sib txuas nruj nreem. Nws belongs rau kev tiv thaiv ntawm cov roj slag pob qij txha.
Kev ua haujlwm yooj yim ntawm cov yam ntxwv tseem ceeb; tsawg sib dhos yuav tsum tau soldered; ntau yam ntawm weldable metallic cov ntaub ntawv; tsawg vuam tsim tau; muaj zog dependence rau qhov zoo ntawm cov welding (nyob ntawm cov kev txawj ua hauj lwm ntawm lub welder thiab nyob rau hauv-site kev ua tau zoo).
Daim ntawv thov dav siv nyob rau hauv shipbuilding, boiler thiab siab hlab ntsha, machinery manufacturing, lub tsev, cov khoom siv tshuaj thiab lwm yam manufacturing thiab txij nkawm industries. Haum rau vuam ntau yam khoom siv hlau, ntau yam thicknesses, thiab ntau yam qauv duab (hauv cov kev lag luam saum toj no).
2. Submerged arc vuam (tsis siv neeg vuam):
Txoj Cai - Lub arc hlawv hauv qab txheej txheej flux. Cov cua sov uas tsim los ntawm qhov hluav taws kub ntawm lub vuam hlau thiab cov vuam yog siv los yaj cov welding hlau, flux, thiab lub hauv paus hlau (solder) los ua ib qho vuam. Nws yog tiv thaiv slag.
Cov yam ntxwv tseem ceeb - vuam tsim tau zoo; zoo weld zoo; tus nqi qis ntawm vuam; ua haujlwm zoo; nyuaj rau vuam hauv qhov chaw; cov kev cai zoo rau kev sib dhos ntawm welded qhov chaw; Nws tsis haum rau vuam nyias daim hlau (thaum lub vuam tam sim no tsawg dua 100A, tsis zoo arc stability) thiab vuam luv luv.
Daim ntawv thov dav siv hauv nkoj tsim, boiler, choj, hoisting machinery thiab metallurgical machinery manufacturing. Submerged arc vuam siv tau rau txhua qhov chaw welded uas nws cov welds tuaj yeem khaws cia rau hauv txoj hauj lwm kab rov tav lossis nws lub kaum sab xis ntawm inclination tsis loj. Lub thickness ntawm lub phaj yuav tsum siab tshaj 5 hli (kom tsis txhob hlawv). Welding ntawm carbon structural steel, tsis tshua muaj alloy structural steel, stainless hlau, tshav kub resistant steel, composite hlau, thiab lwm yam.
3. Cov pa roj carbon dioxide shielded vuam (tsis siv neeg lossis semi-automatic vuam):
Lub hauv paus ntsiab lus: molten electrode arc vuam txoj kev uas siv cov pa roj carbon dioxide los tiv thaiv roj. Nws yog kev tiv thaiv roj. Cov yam ntxwv tseem ceeb - vuam tsim tau zoo; tus nqi qis ntawm vuam; me me vuam distortion (arc cua sov concentration); zoo ntawm vuam; kev ua haujlwm yooj yim; siab txaws tus nqi; nyuaj rau vuam ntawm AC fais fab; cua tsis zoo; Nws tsis tuaj yeem yooj yim weld xeb-xim hlau.
4. MIG/MAG welding (Inert gas/active gas shielded vuam):
MIG vuam txoj cai: arc vuam txoj kev uas siv cov roj inert raws li lub shielding roj thiab vuam hlau raws li lub melting electrode. Lub shielding gas feem ntau yog argon los yog helium los yog lawv cov sib tov. MIG siv cov roj inert, MAG ntxiv me me ntawm cov pa nquag, xws li oxygen, carbon dioxide, thiab lwm yam. rau inert gas.
