Savage A When manufacturing fused fluxes, raw materials are melted into a liquid state with a high temperature electric furnace. The material is then cooled and crushed or ground into the desired particle size.
When making bonded fluxes, the ingredients are dry mixed, then glued together with a liquid binder. This binder may be a liquid such as sodium silicate. After the particles are bonded, they are baked and then sifted through a sieve to attain flux particles of the desired size.
Agglomerated fluxes are manufactured much the same way that bonded fluxes are made. However, instead of a liquid binder, a ceramic binder is used. A higher drying temperature is used, too. The higher drying temperature limits the use of deoxidizers and alloy elements. Fluxes that are mechanically mixed are combinations of two or more bonded or agglomerated fluxes.
Although mechanically mixed fluxes make it possible to create special mixtures for more sensitive welds, these fluxes may separate during storage, use, and recovery of flux. Among the various types of fluxes use in Submerged Arc Welding are the fused flux and the bonded flux. Each of these fluxes offers some advantages and some disadvantages. When making fused fluxes, the raw materials are dry mixed together, and then they are fused or melted into a liquid state by using a high temperature furnace.
After fusion is complete, the fluxes are cooled. This may be accomplished by using a stream of water or with big chill blocks. Once the fluxes are cooled, they are crushed or ground into particles. A variety of particle sizes are made to ensure optimal performance for different applications.
A disadvantage of fused fluxes is that the high temperature used during the manufacture process makes it difficult to add alloys and deoxidizers. The manufacture of bonded fluxes involves combining the dry ingredients, then using a liquid binder such as sodium silicate or potassium silicate to glue the ingredients together. After the bonded mix is made into pellets, the pellets are baked at a low oven temperature. Once the drying of the pellets is complete, the pellets are broken up by using a sieve to attain the desired particle size.
The particles are then packaged for shipping. Submerged Arc Welding SAW is a common welding process that is commonly used in the structural and vessel construction industries.
Originally developed by the Linde - Union Carbide Company, it is commonly used in beam, boom, tractor, and multi-head type rigs. Sub Arc welding requires a continuously-fed tubular or consumable solid electrode and may be fully automatic or semi-automatic.
