Abstract

The invention relates to a flange-short pipe welding device and method. The device comprises a supporting portion, a welding execution portion and a welding gun portion, wherein the supporting portioncomprises supporting blocks, a first motor and a supporting frame, and the first motor drives the supporting frame to rotate; the welding execution portion comprises a second motor, a reduction box and a square rotary table, the second motor drives the square rotary table to rotate through the reduction box, and a plurality of groups of bolt holes used for fixing multiple types of flanges of predetermined specifications and multiple types of welding clamps are formed in the rotary table; and the welding gun portion comprises a first lead screw transmission assembly, a second lead screw transmission assembly, a third lead screw transmission assembly and a welding gun and used for performing fixed-point welding above the welding execution portion. Thus, the flange-short pipe welding deviceprovided by the invention is easy to operate, only simple learning is needed before skilled workers participate in production, in addition, the welding specialization degree is higher, the technological reproducibility is good, the product forming attractiveness is effectively guaranteed and controlled, and bulk duplicating of welding production is facilitated.

Description

technical field [0001] The invention belongs to the field of pipeline welding, and in particular relates to a welding device and method for a flange and a short pipe. Background technique [0002] The connection of the steam pipe needs to be welded with the flange at its end. The current welding of short pipe flanges mostly adopts manual welding and robot automatic welding. Although manual operation has certain advantages, there are also a series of problems. Personnel management is troublesome, worker training cycle is long, welding efficiency is low, welding quality is not high, weld shape is not beautiful, and welding parts need time to polish. Manual welding greatly increases the labor intensity of the operator, and the body is prone to fatigue. The arc light and a large amount of smoke generated by welding also affect the operator's body, resulting in low product processing quality and weak production capacity. Such a welding method has high welding cost, high labor ...
