Mechanical Machine Components
In joint welding components are joined by means of welds at the welding point to become a welded part. A number of welded parts combine to make up a welded assembly and a number of welded assemblies combine to make up a welded structure. Welding has therefore become a manufacturing process which is a determining factor for design. Build-up welding enables worn areas of workpieces to be resurfaced, surfaces of less wear-resistant materials to be reinforced with layers of hard-wearing material (hard facing), base materials not resistant to corrosion to be “clad” with corrosion-resistant materials (cladding) or a reliable bond between materials of a dissimilar composition to be obtained using filler material (buttering). Besides metals, plastics can also be joined by welding.
