 Weld wire. SAW uses electrodes of continuous wire, solid or flux- airvompressoradd2ndtank or metal-cored. Selection airvompressoradd2ndtank depends on base-metal composition and thickness, airvompressoradd2ndtank flux, joint design, and cleanliness. AWS specifications A5. 17 and A5.23 detail filler materials for SAW of carbon and low-alloy steels; A5.9 and A5.1, filler metals weld corrosion-resisting stainless steels and nickel airvompressoradd2ndtank alloys, respectively.Hardfacing ElectrodesHardfacing welds a wear-resistant material to a substrate-base material that is commonly mild, alloy, or stainless steel. Hardfacings can be deposited manually using SMAW electrodes; semiautomaticaly using solid wire and self shielded flux cored electrodes; or automatically by submerged-arc welding. The method chosen depends on the size and accessibility of the area to be surfaced. Select hardfacing materials based on weld-deposit airvompressoradd2ndtank microstructure and the wear situation the part will encounter, with consideration given to thermal treatments applied to the material before and after hardfacing. Deposit chemistry can be crucial in attaining the desired corrosion resistance or wear properties, or for minimizing the risk of solidification cracking. Acceptable deposit chemistry is achieved through the initial choice of consumables, using wire analysis and flux composition, and by specifying the number of weld passes needed airvompressoradd2ndtank to reduce parent-metal dilution to within acceptable limits. With the submerged-arc process, the flux and electrode govern the characteristics of the applied hard facing. For example, those fluxes neutral to manganese and silicon are not necessarily airvompressoradd2ndtank neutral to carbon and chromium, elements that matter most in hardfacing.
