Plasticizing agent for powders
Plasticizers in welding fluxes improve flowability and adhesion to the workpiece. They burn off residue-free during the process.
Physical-Chemical Mechanism of Action
Plasticizing aids in powder form are chemical additives that increase the plastic properties of the powder. They enable smoother application and improve adhesion to the workpiece. During the welding process, they burn off without residue, without damaging the weld pool.
Metallurgical Relevance & Risks in Welding
Proper use of plasticizing aids leads to optimal powder application and improves weld quality. Missing or overdosing can cause problems such as uneven flowability, poor adhesion, or damage to the workpiece.
Workshop Practice & Action Guidelines
Use plasticizing aids in the specified amounts. Check the flowability and adhesion of the powder before use. Ensure that the weld pool is not damaged.
