Abstract: Necessity and importance of automatic bending and welding technology and equipment of steel skeleton，as well as development status and trend at home and abroad were mainly introduced.Aiming at a series of problems such as difficulty of skeleton production，poor safety，inconvenience of existing equipment movement and consumption of a large number of manpower，material resources，etc.，based on existing steel skeleton production technology and equipment at home and abroad，a new type of steel skeleton automatic bending and welding technology and equipment suitable for China′s national conditions was independently developed and researched.Main structure，working principle，working process and key technical characteristics of automatic bending and welding technology and equipment of steel frame were analyzed and emphatically introduced，and its development and application prospect was prospected.
