Nyob rau hauv cov txheej txheem ntawm qhov chaw vuam nrog lub zog cia vuam tshuab, ib qho teeb meem tshwm sim uas tuaj yeem tshwm sim yog qhov tsim ntawm qhov chaw vuam qhov chaw. Qhov tsab xov xwm no yuav tshawb txog cov yam tseem ceeb uas pab txhawb rau qhov chaw weld nyob rau hauv lub zog cia chaw vuam tshuab.
- Electrode Misalignment: Ib qho ntawm cov laj thawj tseem ceeb ntawm qhov chaw ntawm qhov chaw weld yog electrode misalignment. Thaum cov vuam electrodes tsis zoo sib xws, qhov chaw sib cuag ntawm cov electrodes thiab cov khoom ua haujlwm tsis sib xws. Qhov no tuaj yeem ua rau qhov chaw tawm ntawm qhov chaw weld, qhov twg lub zog vuam yog concentrated ntau ntawm ib sab ntawm qhov chaw npaj. Electrode misalignment tuaj yeem tshwm sim los ntawm kev teeb tsa hluav taws xob tsis raug, hnav thiab tsim kua muag ntawm cov lus qhia electrode, lossis kev saib xyuas tsis txaus thiab ntsuas lub tshuab vuam.
- Uneven Workpiece Thickness: Lwm yam uas tuaj yeem ua rau qhov chaw vuam tsis zoo yog qhov muaj qhov tsis sib xws ntawm cov khoom ua haujlwm. Yog hais tias lub workpieces raug welded muaj variations nyob rau hauv thickness, lub vuam electrodes tej zaum yuav tsis ua txawm hu rau lub workpiece nto. Raws li qhov tshwm sim, qhov chaw weld tuaj yeem hloov mus rau sab thinner, ua rau muaj qhov tsis sib xws. Nws yog ib qho tseem ceeb los xyuas kom meej tias cov workpieces raug welded muaj cov thickness zoo ib yam thiab tias txhua qhov kev hloov pauv tau raug suav nrog thaum lub sijhawm vuam txheej txheem.
- Inconsistent Electrode Force: Cov electrode quab yuam siv thaum lub sij hawm vuam chaw ua lub luag haujlwm tseem ceeb hauv kev ua tiav qhov tsim nyog qhov chaw vuam. Yog hais tias lub electrode quab yuam tsis sib xws nyob rau hauv tag nrho cov welding cheeb tsam, nws yuav ua tau nyob rau hauv off-center weld me ntsis. Cov yam ntxwv xws li hnav-tawm electrode springs, kev hloov tsis txaus ntawm electrode quab yuam, los yog cov teeb meem ntawm lub tshuab vuam tuaj yeem ua rau tsis zoo electrode quab yuam faib. Kev tshuaj xyuas tsis tu ncua thiab kev saib xyuas ntawm lub tshuab vuam, nrog rau kev kuaj xyuas thiab kho lub zog electrode, tuaj yeem pab tiv thaiv qhov teeb meem no.
- Qhov tsis raug vuam tsis raug: Kev teeb tsa tsis raug ntawm vuam tsis zoo, xws li vuam tam sim no, vuam lub sij hawm, thiab electrode siab, tuaj yeem ua rau qhov chaw vuam tsis zoo. Yog hais tias qhov vuam tsis haum tsis haum rau cov khoom ua haujlwm tshwj xeeb thiab tuab, qhov chaw vuam yuav txawv ntawm qhov chaw xav tau. Nws yog ib qho tseem ceeb los xyuas kom meej tias cov vuam tsis raug raug teeb tsa raws li cov lus pom zoo los ntawm cov chaw tsim khoom siv vuam tshuab thiab coj mus rau hauv tus account cov yam ntxwv tshwj xeeb ntawm cov khoom siv ua haujlwm.
Off-center weld me ntsis hauv lub zog cia qhov chaw vuam tshuab tuaj yeem raug ntaus nqi rau ntau yam, suav nrog electrode misalignment, tsis sib luag workpiece thickness, tsis sib haum electrode quab yuam, thiab tsis raug vuam tsis. Los ntawm kev hais txog cov xwm txheej no los ntawm kev sib raug zoo electrode, tswj xyuas cov khoom ua haujlwm zoo ib yam, ua kom cov khoom siv hluav taws xob tsis sib xws, thiab teeb tsa cov vuam tsis zoo, qhov tshwm sim ntawm qhov chaw vuam qhov chaw tuaj yeem txo qis. Kev tshuaj xyuas tsis tu ncua, kev saib xyuas, thiab ntsuas lub tshuab vuam yog qhov tseem ceeb rau kev tswj xyuas qhov kev ua haujlwm vuam zoo thiab ua tiav cov khoom siv vuam zoo.
