JQ·YJ501-1L yog titanium dioxide CO2gas shielded flux-cored welding hlau, uas muaj kev vuam zoo heev nrog cov mos mos thiab du arc, tsis tshua muaj spatter theem, tsis muaj zog slag tshem tawm muaj peev xwm thiab pom cov hlaws dai. Nws raug tso cai rau txhua txoj haujlwm vuam. Lub vuam efficiency yog siab. Cov hlau deposited yog toughened los ntawm cov kab lus, uas muaj zoo heev tsis tshua muaj kub toughness ntawm -40 degree thiab zoo tawg kuj.
Lub hom phiaj
Cov khoom siv yog siv rau vuam cov qauv hlau nrog tensile lub zog ntawm 490MPa, feem ntau siv nyob rau hauv cov teb xws li nkoj, txuas hniav, siv machinery, marine engineering, thee mining machinery, siv machinery thiab lwm yam.

Cov kev ceev faj
1. Lub workpiece yuav tsum degreased thiab derusted ua ntej welding.
2. Thaum vuam, cov roj ntws feem ntau yog 20-25L / min.
3. Thaum vuam flux-cored vuam hlau, qhov ntev txuas ntxiv yuav tsum yog 15-25 hli.
4. Cov av noo ntawm vuam hlau warehouse yuav tsum tau khaws cia hauv qab 60%.
5. Lub vuam hlau uas tsis muaj lub tshuab nqus tsev yuav tsum tsis txhob muab khaws cia rau ntau tshaj ib nrab xyoo thiab vuam hlau nrog lub tshuab nqus tsev yuav tsum tsis txhob muab khaws cia rau ntau tshaj ib xyoos.
