What is coalescence in welding?

[organicbird383]

Coalescence is the union of colloidal particles into a group or larger unit as a result of molecular attraction on the surfaces of the particles. It is the fusing of molten particles to form a continuous film. Coalescence is a term used in welding and brazing, emulsion and coating.

Coalesce is when different elements of something join together and become one.

Also, what is coalescence in paint? Eastman coalescents enable maximum film formation in latex paints, often improving overall paint performance. Coalescent works by softening the latex particles, allowing them to fuse into a tough, continuous film. Common coalescents include ester alcohols, esters, and glycol ethers.

Also to know, what is coalescence process?

Coalescence is the process by which two or more droplets, bubbles or particles merge during contact to form a single daughter droplet, bubble or particle. It can take place in many processes, ranging from meteorology to astrophysics. In meteorology, its role is crucial in the formation of rain.
