Effect of welding parameters on welded steel wire mesh

Generally concrete is reinforced with ribbed bars. In certain applications, it is desirable to use welded mesh and are used in most reinforced concrete structures (buildings, roads, tunnels and prefabricated components).

Welded mesh are generally electrowelded (PW: Projection Welding), where the heat necessary to produce the joint is originated by the resistance that oppose the workpieces to the flow of electric current, under the action of mechanical pressure. This process presents various operational parameters which affect the quality of welded joints and the microstructural evolution that takes place during welding. IRAM-IAS U 500-06 standard establishes the requirements to be met by welded steel mesh.
