Cladding is the application of one material over another to provide layer intended to control the infiltration of weather elements or for aesthetic purposes. Cladding does not necessarily have to provide a waterproof condition but is instead a corrosion control element. There are several types of cladding, one of them which HADIDSA uses is weld cladding.
Weld cladding is typically between 2 and about 20 mm thick. It can be applied using a variety of welding processes including manual metal arc (MMA), gas tungsten arc welding (GTAW), gas metal arc welding (GMAW), submerged arc welding (SAW), flux cored arc welding (FCAW), plasma transferred arc welding (PTAW) and laser deposition.
During weld cladding the integrity of the clad layer and adequate toughness of the heat-affected zone (HAZ) must be ensured whilst simultaneously maintaining the substrate material properties.
High quality clad welding needs through understanding of the metallurgy of the substrate as well as the hard facing material.
Utilizing expertise in all welding processes, as well as metallurgists with knowledge of corrosion-resistant alloys and the welding of ‘difficult’ parts from 2" up to 72", has made HADIDSA capable to offer new service to its customers they need cladded parts.
