Fused welding flux
Fused welding flux is a homogeneous powder produced by melting and granulating. It has high physical and chemical stability and improves weld quality.
Physical-Chemical Mechanism of Action
Fused welding flux consists of fine, homogeneous particles produced by controlled melting and subsequent granulation. This process ensures a uniform chemical composition and minimizes uneven deformations.
Metallurgical Relevance & Welding Risks
The high homogeneity of fused welding flux leads to improved weld quality with lower stress build-up and fewer cracks. It also reduces the risk of hot cracking and increases the toughness of the joint. However, incorrect application or inadequate control of the flux content can lead to uneven welding operations and reduced strength.
Workshop Practice & Instructions
Use fused welding flux in the specified amount and control the weld pool temperature precisely. Too much flux can cause uneven deformations, while too little affects homogeneity. Make sure the flux is completely molten and covers the weld evenly.
