Problems solved by technology

[0002] Welding is a manufacturing process and technology for joining metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. During the welding process of high-strength precision welded pipes, the strength will be weakened due to the excessive joint of the two steel pipes. Moreover, stress deformation will occur at the joint due to high temperature. The existing high-strength precision welded pipe welding device lacks a leveling function and a real-time tightening function, resulting in an excessively large gap at the joint of the two steel pipes and weak strength. The straightness of the two steel pipes cannot be adjusted again due to welding stress deformation, and the welding accuracy is not good, which needs further improvement

Abstract

The invention relates to a high-strength precise weld pipe welding device and an operation method. The welding device comprises a support, a supporting bar, a carrier plate, a carrier bar, a chassis,a thread base and a locating assembly. The locating assembly comprises a rotating block, a handle, an inner shaft, a first thread sleeve, a spring, a second thread sleeve, a short thread shaft, a longthread shaft, an end cover, a sleeve and a calibration assembly. The calibration assembly comprises a traction pin, an L-shaped traction block, a swing rod, a moving block, a partition plate, a double-screw bolt, a nut and an arc-shaped block. The welding device has a leveling function, the locating assembly and the calibrating assembly can be operated again to adjust the flatness degree of two steel pipes, and operation is easy and convenient.
