When and Why choose the Solid welding wire or Flux cored welding wire?
When and Why choose the Solid welding wire or Flux cored welding wire? You may confused when choosing the welding wire for your weld work. Solid welding wire or Flux cored welding wire which is better? Today I can tell you both of the wire can create good weld work if you use them properly. However there are some differences or consideration should be bear in mind when you choose them for your GMAW welding work: Factors should to considerSolid Welding wire (GMAW wire)Gas shielded Flux cored welding wire (FCAW wire)External shielded Gas It is necessary. Usually, 100% CO2 or Co2/Ar2 blendedIt is necessary. Usually, 100% CO2 or Co2/Ar2 blended. Thickness of the base metalVery good for thin plate. That is why the dia. of the wire start from 0.8MMCan weld thicker plate. So, the flux cored welding wire usually start from 1.2MMCondition of the base metalCan only weld clean metal. Can weld the base metal has some scales. As the flux inside the wire has deoxidizer.Deposition rate By short-circuit transfer, the deposition rate is low Has higher deposition rate. Mechanical properties Generally, the strength of a weld deposit made with a solid GMAW wire is limited to the strength of the electrode.Because slagging agents and other components are added to their cores, FCAW Wire can achieve good mechanical propertiesPost-weld treatment:Silicon islands can be deposited during GMAW that might need to be removed before painting or coating. However, GMAW with solid wire generally is a clean process that requires minimal postweld operations.. FCAW wire requires the most labor-intensive cleanup because of the slag it leaves on the weld. You will need to remove slag between passes in multiple-pass applications and before painting or coating.Easiness of welding Required skilled and well trained operatorIt does not need skilled and well trainer operator compared with Solid wire. Price It is economic compared with FCAW It is little costly compared with solid Next Pages are about the understandings of the GMAW wire and FCAW wire.
