MIG Chaw Ib qho ua rau MIG vuam spatter yog nrawm nrawm lossis tsis sib xws nrog koj cov xaim pubSpatter tshwm sim thaum cov xaim xaim nkag mus rau hauv lub pas dej. … Nws tseem tuaj yeem tsim ib lub taub hau nplaum nplaum thaum cov hlau yaj nyob ze nws. Cov residue tsim, ua rau tus nqi noj tsis sib haum vim yog cov hlau nplaum.
Kuv yuav ua li cas thiaj tiv thaiv kuv qhov tawg ntawm MIG vuam?
MIG Welder
Yuav txo MIG vuam spatter, koj cov hlau yuav tsum tau noj tsis tu ncua ntawm qhov nro kom zoo, tsis muaj snagging lossis lwm yam kev txwv. Ib tug smooth, zoo ib yam hlau pub ceev yuav tsum tau muab kom tiav ib tug huv weld. Cov pa tiv thaiv yuav tsum tau ntws tawm ntawm tus nqi zoo.
Yuav ua li cas kho vuam spatter?
Yuav daws teeb meem, txo cov amperage los ntawm kev ua kom qeeb ntawm cov xaim, lossis nce qhov voltage - lossis nrhiav qhov sib npaug ntawm ob. (Siv ntawm kev kho kom zoo ntawm koj qhov chaw thiab kev sim welds kom txog thaum koj pom tias tsis muaj qhov sib tsoo.) Polarity: Nco ntsoov tias nws yog lawm.
Qhov cuam tshuam ntawm kev sib tsoo hauv vuam yog dab tsi?
Weld spatter muaj cov pob me me ntawm cov hlau molten uas tau tsim nyob ze ntawm qhov vuam arc uas lo rau cov roj shroud ntawm cov phom vuam thiab thaiv cov roj ntws. Cov teeb meem tshwm sim muaj xws li kev sib tsoo lo rau cov khoom ua haujlwm thiab / lossis cov cuab yeej, raug mob rau cov neeg ua haujlwm, ntxuav tu, porosity thiab poob ntawm cov khoom.
Vim li cas kuv MIG welds phem?
Wire feed speed/amperage low- Ib tug xub, oftentimes convex bead with poor tie-in at the toes of the weld marks insufficient amperage. Kev nrawm nrawm dhau - Cov hlaws nqaim nqaim nrog txoj hlua khi tsis txaus ntawm cov ntiv taw ntawm cov vuam, qhov nkag tsis txaus thiab cov hlaws hlaws tsis sib haum yog tshwm sim los ntawm kev mus nrawm dhau.
