Abstract

The invention relates to a welding device for straight seam single-side welding and double-side forming of conical steel pipes, which belongs to the field of machining. The welding device comprises an adjustable welding device, a welding bracket and a bearing travelling car, the adjustable welding device comprises a vertical rod connected with a telescopic sleeve through a sliding device, the sliding device is connected with a motor at the top of the vertical rod through a rope, a telescopic rod is arranged in the telescopic sleeve, and a welding device is arranged at an end of the telescopic rod. By the aid of the adjustable welding device and the bearing travelling car, the welding device for straight seam single-side welding and double-side forming of the conical steel pipes can meet the machining requirement of the conical steel pipes on straight seam welding, and is simple in structure and wide in adaptability. The effects of single-side welding and double-side forming can be achieved, and the problem of multiple welding of a welding seam is solved during straight seam welding. Both seam quality and welding efficiency are improved, consumption of welding materials and waste of manpower resources are remarkably reduced, physical injury of welders during inner seam welding is effectively avoided.

Description

technical field [0001] The invention relates to a tapered steel pipe straight seam single-sided welding double-sided forming welding device, which belongs to the field of mechanical processing. Background technique [0002] At present, the straight seam welding process of tapered steel pipes with circular or polygonal cross-sections is as follows: after the steel pipe parts are synthesized into steel pipes, the workpiece is placed on a fixed frame, and the pipe fittings are squared according to the straight seam level for welding. In the welding process, the outer straight seam is strengthened by an automatic submerged arc welding after the bottom welding is carried out by carbon dioxide gas shielded welding. The inner side of the straight seam is welded again with carbon dioxide gas shielded welding or manual arc welding. This traditional welding process has been followed for many years. It is time-consuming to weld the inner and outer seams separately, which affects produ...
