Abstract

The invention relates to the technical field of laser welding, in particular to a continuous pipe laser welding device. The continuous pipe laser welding device comprises a machine base platform, straightening conveying mechanisms, a continuous pipe fixing and clamping mechanism, a continuous pipe adjusting and clamping mechanism, an all-position welding ring rail mechanism and a laser head. The two straightening conveying mechanisms are arranged above the machine base platform. The continuous pipe fixing and clamping mechanism and the continuous pipe adjusting and clamping mechanism are fixedto the machine base platform, and the continuous pipe fixing and clamping mechanism and the continuous pipe adjusting and clamping mechanism are arranged between the two straightening conveying mechanisms. The all-position welding ring rail mechanism is fixed to the machine base platform, and the all-position welding ring rail mechanism is arranged between the continuous pipe fixing and clampingmechanism and the continuous pipe adjusting and clamping mechanism. The laser head is connected to the all-position welding ring rail mechanism. According to the continuous pipe laser welding device,the laser head can move in the circumferential direction on the all-position welding ring rail mechanism, and welds a weld seam of a continuous pipe at multiple angles, and the welding efficiency andwelding quality are improved.

Description

technical field [0001] The invention relates to the technical field of laser welding, in particular to a continuous tube laser welding device. Background technique [0002] Coiled Tubing (CT tube for short) is mainly used for oil and gas and combustible ice drilling operations. It is a high-strength and high-toughness coiled tubing that can be wound on a drum. It has good fatigue resistance and flexibility. . Coiled tubing is widely used in drilling, workover, completion, logging and other processes in oil and gas fields. During coiled tubing operation and service, corrosion, mechanical damage, wall thickness reduction, and even fracture and bursting usually occur. Therefore, cutting off defective coiled tubing and butt-welding the coiled coiled tubing in good condition is a necessary work especially at the drilling production site. In the prior art, the welding efficiency of coiled tubing is low. Contents of the invention [0003] Embodiments of the present invention ...
