What's the best way to prepare for welding?
To prepare for welding one should remove defects, especially cracks, by dry chipping with a rounded tool or by hand milling, to obtain a smooth area. One should never attempt to weld on the original casting external rough surface without first removing the oxidized layer.See all results for this questionWhat is the process of raising the temperature of a part before welding?As the name implies, it is the process of raising the temperature of a part before welding it. This preheat temperature has to be maintained throughout the welding procedure. In some cases it might be necessary to continue heating the part during welding, but sometimes the heat input from the welding itself maintains that temperature.See all results for this questionWelding: Principles and Applications | Larry Jeffus | downloadAdvancing rapidly from basic concepts and processes to today's most complex, cutting-edge welding technologies and practices, this comprehensive text features valuable information on topics such as welding metallurgy, metal fabrication, weld testing and inspection, joint design, job costing, and environmental and conservation tips.
