Ua rau Tsis tiav Fusion hauv Spot Welding?

fusion tsis tiav, feem ntau hu ua "txias weld" lossis "tsis muaj fusion," yog qhov teeb meem tseem ceeb uas tuaj yeem tshwm sim thaum lub sij hawm siv cov txheej txheem vuam siv.chaw vuam tshuab. Nws hais txog qhov xwm txheej uas cov hlau molten tsis ua tiav nrog cov khoom siv hauv paus, ua rau muaj qhov tsis muaj zog thiab tsis muaj kev sib koom ua ke. Kab lus no tsom mus tshawb txog ntau yam uas tuaj yeem ua rau tsis tiav fusion hauvqhov chaw vuam.

Welding Tam sim no

Vuam tam sim no yog ib qho tseem ceeb tshaj plaws nyob rau hauv lubtxheej txheem vuam, thiab nws muaj qhov sib npaug ntawm cov cua sov tsim thaum lub sij hawm vuam. Tsis txaus vuam tam sim no yog ib qho ntawm cov laj thawj tseem ceeb rau kev tsis sib haum xeeb. Thaum cov vuam tam sim no tsawg dhau, nws yuav tsis tsim kom muaj cua sov txaus kom yaj lub substrate tag nrho. Yog li ntawd, cov hlau molten tsis tuaj yeem nkag mus thiab fuse kom raug, ua rau tsis tiav fusion ntawm vuam interface.

Tsis txaus Electrode Siab

Lub zog hluav taws xob tsis txaus kuj tuaj yeem ua rau tsis tiav fusion. Hluav taws xob siab yog siv rau lub workpiece kom ntseeg tau tias muaj kev sib cuag thiab nkag mus thaum vuam. Yog tias lub zog hluav taws xob tsawg dhau lawm, qhov chaw sib cuag ntawm qhov chaw ua haujlwm thiab qhov chaw ua haujlwm yog me me, thaum vuam, lub atomic txav ntawm cov sib koom ua ke yuav tsis txaus, yog li ntawd ob lub vuam pob qij txha yuav tsis zoo tag nrho.

Electrode Alignment tsis raug

Kev sib raug zoo ntawm cov electrodes tsis raug tuaj yeem ua rau qhov tsis sib xws ntawm cov cua sov, ua rau tsis tiav fusion. Thaum cov electrodes tsis sib haum, cov cua sov uas tsim los ntawm cov txheej txheem vuam yuav tsis raug muab sib npaug thoob plaws hauv qhov chaw vuam. Qhov kev faib hluav taws xob tsis sib xws no tuaj yeem ua rau tsis tiav fusion hauv cheeb tsam. Yog li ntawd, ua ntej kev sib txuas ua haujlwm pib, nco ntsoov xyuas seb lub tshuab hluav taws xob sab sauv thiab sab qis yog qhov tseeb, yog tias tsis ua raws, nws yog qhov yuav tsum tau ua kom zoo los ntawm cov cuab yeej.

Workpiece Surface Contamination lossis Oxidation

Kev kis kab mob lossis oxidation ntawm qhov chaw ua haujlwm tuaj yeem cuam tshuam nrog kev sib xyaw ua ke thaum lub sijhawm vuam. Cov kab mob sib kis, xws li roj, av, lossis cov coatings, ua qhov cuam tshuam ntawm cov hlau molten thiab substrate, inhibiting melting. Ib yam li ntawd, oxidation nto tuaj yeem tsim ib txheej oxide uas tiv thaiv kev sib raug zoo thiab fusion. Piv txwv li, thaum koj xav weld lub fin machined los ntawm lubfincevtshuabnyob rau hauv lub raj, yog hais tias lub nto ntawm lub raj yog xeb, lub vuam yuav tsum tsis yog-fusion, yog li ntawd lub welded sib koom yuav tsis ruaj khov thiab cuam tshuam rau qhov zoo ntawm cov khoom.

Lub sijhawm luv vuam

Lub sij hawm vuam tsis txaus tiv thaiv cov hlau molten los ntawm ntws txaus thiab sib txuas nrog cov khoom siv hauv paus. Yog tias lub sijhawm vuam luv dhau lawm, qhov kev sib cuag ntawm cov hlau tsis yog tag nrho fused ua ntej qhov kawg ntawm qhov paug, thiab qhov kev sib xyaw ua ke tsis txaus yuav ua rau cov vuam tsis muaj zog thiab tsis muaj kev ntseeg siab.

Kev nkag siab txog yam uas ua rau tsis tiav qhov chaw vuam fusion yog qhov tseem ceeb rau kev ua kom zoo welds. Los ntawm kev daws cov teeb meem ntawm vuam tsis txaus tam sim no, tsis muaj hluav taws xob tsis txaus, tsis raug electrode alignment, nto paug los yog oxidation, thiab lub sij hawm vuam tsis txaus, koj tuaj yeem txo qhov tshwm sim ntawm qhov tsis tiav thaum vuam ua haujlwm, kom tag nrho cov vuam zoo tuaj yeem txhim kho tau zoo.
