Flux is moved through the drying oven using gravity and a continuous rocking motion. Short cycling time. Oven continously redries the flux. Multiple welding operations can be supported due to the per hour output of 55 to 85 lbs. Moisture contaminated SAW fluxes can cause porosity, cracking and introduction of hydrogen into the weld joint.
Most technical specifications require that agglomerated fluxes be dry or be dried prior to use.
For the first time, it is possible to have complete and uniform drying on the shop floor that equals that obtained by the original flux manufacturer. This is accomplished by heating uniformly thin layers of flux particles in a precision manner. Flux is poured into the top of the oven, then progresses downward via gravity and a gentle rocking motion through a series of angled baffles. The rocking motion and progression of flux only begins once the preset and electronically controlled drying temperature has been achieved. This temperature control feature prevents over or under temperature drying conditions and is especially important when drying agglomerated or bonded fluxes.
