Problems solved by technology

However, in the existing technology, there is no good way to preheat large pipe diameters. The firepower is not concentrated, the heating range is small, the flame is weak, the efficiency is low, the preheating temperature cannot be accurately controlled, and the gas control is not stable. These obvious defects have been eliminated. The welding quality of large diameter pipe fittings cannot be guaranteed

Abstract

The invention relates to an all-position automated pipe preheating system, which belongs to the technical field of automated welding equipment. The all-position automated pipe preheating system mainly comprises a moving trolley, an adjusting slider, a lifting adjustor, an angle adjustment mechanism, a gun part and a gas circuit system. The adjusting slider is mounted on the moving trolley, the lifting adjustor is mounted on the adjusting slider, the angle adjustment mechanism is connected with the gun part, the whole body composed of the angle adjustment mechanism and the gun part is mounted on the lifting adjustor, and the gas circuit system meets the requirement of pipe preheating on gas supply by means of a control system. The all-position automated pipe preheating system is applicable to weld preheating processes for pipes with different large calibers and different wall thicknesses, has the advantages of concentrated fire power, wide heating range, accurate temperature control, stable gas supply control, automatic preheating temperature correction and the like, and is convenient and safe to operate.

Description

technical field [0001] The patent of the invention is an all-position automatic preheating system for pipe fittings, which belongs to the technical field of automatic welding equipment. Background technique [0002] Preheating pipe fittings before welding is an effective way and way to improve welding performance and welding quality. Preheating before welding can reduce the temperature difference in the heat-affected zone, improve the stress condition, reduce the cooling rate, reduce the degree of hardening, and prevent welding cracks. Preheating before welding for large pipe diameters is particularly important. However, in the existing technology, there is no good method for preheating large pipe diameters, such as lack of concentrated firepower, small heating range, weak flame, low efficiency, inability to accurately control the preheating temperature, and unstable gas control. These obvious defects have been eliminated. The welding quality of large diameter pipe fitting...
