The core principle of welded wedge wire mesh is to apply localized high-temperature fusion at the intersection of the V-shaped (or wedge-shaped) wires and the supporting ribs, forming a strong, uniform, and continuous metal joint. This results in a filter or screening structure with high open area, anti-clogging properties, and high structural strength.
Local fusion welding forms a metallurgical bond: A concentrated heat source (such as a laser or electric arc) is applied at the intersection, causing the metal to locally melt and fuse. After cooling, a high-strength joint is formed, ensuring the integrity of the overall structure.
Protecting non-welded areas: To prevent material performance degradation or deformation caused by the heat-affected zone, heat input needs to be controlled, and the surface of the cladding layer (such as stainless steel) needs to be protected against arc damage.
Layered welding sequence: For composite material wedge wire mesh, the base layer is typically welded first, followed by the transition layer, and finally the cladding layer, to ensure corrosion resistance and joint quality.
Automated welding improves precision: Utilizing advanced processes such as laser automatic welding avoids problems like uneven energy distribution, wire breakage, or deformation associated with manual welding, ensuring uniform gap dimensions.
