Tshav kub thaum pib ntawm cov txiv ntoo projection vuam tuaj yeem ua rau muaj kev txhawj xeeb vim nws yuav qhia tau tias muaj teeb meem uas tuaj yeem cuam tshuam qhov zoo ntawm cov vuam. Hauv tsab xov xwm no, peb yuav tshawb txog cov laj thawj uas tshwm sim hauv cov noob txiv qhov projection vuam thiab sib tham txog cov tswv yim los daws cov teeb meem zoo.
- Contaminated Surfaces: Ib qho ntawm cov laj thawj tseem ceeb rau qhov ua rau cov txiv ntoo ua haujlwm vuam yog qhov muaj cov kab mob ntawm cov mating ntawm cov txiv ntoo thiab cov khoom ua haujlwm. Cov kab mob xws li roj, roj, xeb, lossis nplai tuaj yeem tsim kev thaiv ntawm cov electrode thiab cov khoom ua haujlwm, ua rau arcing thiab sparking. Ua tib zoo ntxuav qhov chaw ua ntej vuam yog qhov tseem ceeb heev kom tshem tawm cov kab mob no thiab txo qis qis.
- Kev sib cuag hluav taws xob tsis zoo: Kev sib cuag hluav taws xob tsis txaus ntawm cov khoom siv hluav taws xob thiab cov khoom ua haujlwm tuaj yeem ua rau tawg paj thaum pib ntawm vuam. Qhov no tuaj yeem tshwm sim vim kev sib txuas xoob, hnav-tawm lossis puas electrodes, lossis tsis txaus siab rau ntawm qhov chaw ua haujlwm. Ua kom muaj kev sib raug zoo ntawm electrode, nruj txhua qhov kev sib txuas hluav taws xob, thiab tswj cov electrodes kom zoo tuaj yeem pab txhim kho kev sib cuag hluav taws xob thiab txo qhov tawg.
- Tsis yog Welding Parameters: Cov vuam tsis tsim nyog, xws li cov khoom siv vuam tam sim no ntau dhau los yog lub sij hawm ntev welding, tuaj yeem ua rau muaj qhov tshwm sim ntawm cov txiv ntoo projection welding. Cov tam sim no ntau dhau tuaj yeem ua rau muaj qhov tsis sib xws hauv kev faib hluav taws xob, ua rau arcing thiab sparking. Ib yam li ntawd, lub sijhawm vuam ntev ntev tuaj yeem ua rau muaj cua sov ntau dhau, ua rau muaj qhov tshwm sim ntawm qhov tshwm sim. Optimizing vuam tsis raws li cov khoom thickness, txiv ntseej loj, thiab tshwj xeeb vuam yuav tsum yog qhov tseem ceeb los tiv thaiv sparking.
- Inconsistent Workpiece Preparation: Inconsistent workpiece npaj, xws li unevenly los yog tsis txaus flattened nto, yuav ua rau kom sparking thaum lub sij hawm txiv ntseej projection welding. Qhov chaw tsis sib xws tuaj yeem ua rau tsis sib xws ntawm cov vuam tam sim no, ua rau arcing thiab sparking. Nws yog ib qho tseem ceeb los xyuas kom meej tias cov workpiece nto yog npaj kom zoo, flattened, thiab ua raws li cov kev cai ntawm niaj hnub kev faib tawm thiab txo qhov sparking.
- Tsis txaus siab: Tsis txaus siab siv thaum lub sij hawm vuam txheej txheem yuav ua rau sparking nyob rau hauv txiv ntseej projection welding. Tsis txaus siab tuaj yeem tiv thaiv kev sib cuag ntawm cov electrode thiab cov khoom ua haujlwm, ua rau arcing thiab sparking. Kev tuav lub siab tsim nyog thoob plaws hauv lub voj voog vuam ua kom muaj kev sib cuag ntawm electrode-rau-workpiece thiab txo qhov tawg.
Kev tawg thaum lub sij hawm pib ntawm cov txiv ntoo projection vuam tuaj yeem raug ntaus nqi rau ntau yam, nrog rau cov chaw tsis huv, tsis muaj hluav taws xob tiv tauj, tsis raug vuam tsis raug, kev npaj ua haujlwm tsis zoo, thiab tsis txaus siab. Los ntawm kev hais txog cov teeb meem no los ntawm kev tu kom huv si, ua kom muaj kev sib cuag hluav taws xob zoo, ua kom zoo dua cov vuam tsis zoo, kev npaj ua haujlwm zoo ib yam, thiab tswj kom txaus siab, cov neeg ua haujlwm tuaj yeem txo qhov tawg thiab ua tiav cov welds zoo. Ua raws li cov tswv yim no txhawb nqa cov txheej txheem welding zoo thiab txhim khu kev qha.
