The role of wollastonite in welding rod Wollastonite mainly plays the following roles in the welding rod: Melting and slagging additives: wollastonite can inhibit the discharge during the welding process, reduce splashing, and improve the fluidity of the slag. This can make the weld molding more clean and beautiful .
Enhanced mechanical strength: wollastonite can provide calcium oxide to the electrode, and bring silica, thus obtaining a highly alkaline slag. This slag helps to reduce porosity and other defects in the joint, thereby increasing the mechanical strength of the weld.
Improve oxidation resistance and corrosion resistance: Adding wollastonite to flux-cored wire can improve the oxidation resistance and corrosion resistance of the wire, while increasing the fluidity and stability of welding, reducing the generation of welding defects and cracks. Improve the use efficiency of alloying elements: wollastolite can also adjust the fluidity and wettability of metal liquid in welding, effectively control the shape and size of the weld, so as to improve the use efficiency of alloying elements and reduce welding cost.
Improve the weld surface quality and mechanical properties: the addition of wollastonite can also improve the quality and mechanical properties of the weld surface, and improve the strength and toughness of the welded joint. Reduce the amount of spatter and dust: in the formula of titanium junction 421 electrode, wollastonite can replace part of the carbonate, thereby reducing the amount of spatter and dust, while reducing the amount of carbon ferromanganese, reducing the cost of the formula .
Increase the bonding force and fluidity of the sintered flux: wollastonite as a filler material can increase the density and hardness of the sintered flux and improve the welding quality .
Adjust the chemical composition and physical properties of the sintered flux: wollastonite can adjust the chemical composition and physical properties of the sintered flux to adapt to different welding environments and requirements .
In summary, wollastonite plays a multi-dimensional role in the electrode, from melting, slagging to enhance mechanical strength, improve oxidation resistance and corrosion resistance, to improve the surface quality and mechanical properties of the weld, as well as adjust the bonding force and
fluidity of the flux, are its important functions in the electrode.
