Puas Yog Qhov Muaj Cov Txheej Txheem Oxide ntawm Electrode Tip ntawm Resistance Vuam cuam tshuam rau nws qhov zoo?

Cov txheej txheem oxide ntawm cov lus qhia tsis zoo-welding electrode tuaj yeem ua rau muaj kev cuam tshuam tsis zoo ntawm cov vuam zoo, feem ntau tshwm sim hauv cov hauv qab no:

1. Kev tiv thaiv kev tiv thaiv ntxiv  

  Cov txheej oxide nce qhov kev sib cuag ntawm lub taub hau electrode thiab cov khoom ua haujlwm, yog li ua kom muaj kev tiv thaiv tam sim no. Qhov no txo ​​qhov kev hloov pauv zoo ntawm tam sim no, ua rau qhov tsis sib xws hauv cheeb tsam kub ntawm qhov chaw vuam thiab degraded weld zoo.

2. Txo qhov vuam ruaj khov  

  Lub xub ntiag ntawm oxide txheej ua rau kev sib cuag ntawm electrode tip thiab workpiece tsis ruaj khov, feem ntau ua rau muaj kev cuam tshuam hauv cheeb tsam arc. Cov kev cuam tshuam no ua rau muaj qhov kub thiab txias ntawm qhov chaw weld, tsis ruaj khov weld zoo, thiab tuaj yeem cuam tshuam tag nrho fusion ntawm weld nugget.

3. Lower Weld Strength  

  Cov oxide txheej impairs nugget tsim thiab kev sib txuas zoo, txo qis tag nrho cov vuam lub zog. Thaum vuam, nws tuaj yeem ua rau tsis tiav kev nkag mus, porosity, slag inclusions, lossis lwm yam tsis xws luag uas cuam tshuam rau kev sib koom ua ke thiab lub peev xwm thauj khoom.

4. Shortened Electrode Lub neej  

  Thaum muaj cov txheej txheem oxide tam sim no, qhov chaw sib cuag tiag tiag ntawm cov khoom siv hluav taws xob thiab cov khoom ua haujlwm tau txo qis, tsom rau tam sim no hauv cov cheeb tsam me. Qhov no hauv cheeb tsam cua sov thiab hnav ceev electrode-ntsia deterioration thiab shorten electrode lub neej.

Txhawm rau tiv thaiv cov teebmeem tsis zoo no, cov kev ntsuas hauv qab no yuav tsum tau ua:

- Kev tu tsis tu ncua  

 Nquag ntxuav lub electrode-ntsia saum npoo kom tshem tawm cov oxides thiab cov kab mob, ua kom lub ntsej muag du thiab ua kom muaj hluav taws xob zoo.

- Siv cov tshuaj tiv thaiv oxidation  

 Qhia oxidation inhibitors thaum lub sij hawm vuam kom qeeb oxide-txheej tsim thiab txo nws cov kev cuam tshuam rau weld zoo.

- Kev ua kom zoo ntawm Vuam Parameters  

 Xaiv cov kev sib txuas uas tsim nyog - tam sim no, lub sijhawm, thiab lub zog electrode - kom xa cov cua sov thiab siab txaus, yog li txo qis kev cuam tshuam ntawm cov txheej txheem oxide.

- Kev tshuaj xyuas ib ntus thiab tu  

 Txhua zaus tshuaj xyuas thiab tswj cov khoom siv vuam kom ruaj khov thiab txo cov teeb meem vuam zoo tshwm sim los ntawm cov khoom siv tsis raug.
