Automatic welding process of stainless steel pipes

Abstract

The invention relates to an automatic welding process of stainless steel pipes, in particular to an automatic welding fixture for the stainless steel pipes. The automatic welding fixture comprises a fixture table, a butt-joint synchronous driving mechanism arranged on the lower part of the fixture table, two positioning clamping mechanisms for correspondingly positioning and clamping two stainlesssteel pipes one to one, a positioning baffle plate mechanism for positioning welding end ports of the two stainless steel pipes and a fine-adjusting correcting mechanism for fine-adjusting and correcting. According to the fixture related in the process, the welding auxiliary butt-jointing can be conducted for the stainless steel pipes welded vertically at two end ports, the accurate butt-jointingof the welding end ports of the two stainless steel pipes can be automatically and quickly achieved, the accuracy and tightness of the welding end port butt-jointing are ensured, thus the welding quality of a welding product is ensured, and the welding strength and welding beautiful degree are ensured.

Description

technical field [0001] The invention relates to the technical field of welding processing, and specifically proposes an automatic welding process for stainless steel pipes. Background technique [0002] Stainless steel pipe is a hollow long round steel material, which is widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial pipelines and mechanical structural components. At the same time, it is light in weight, so it is also widely used in the manufacture of mechanical parts and engineering structures. [0003] In the actual processing process, according to the actual needs of the layout of steel pipe components, it is often necessary to weld stainless steel pipes, the most common of which are straight line welding and vertical welding, where vertical welding includes the vertical welding of two stainless steel pipe ports. Welding and vertical welding of one stainless steel pipe port relative to the side wall of t...

Problems solved by technology

[0003] In the actual processing process, according to the actual needs of the layout of steel pipe components, it is often necessary to weld stainless steel pipes, the most common of which are straight line welding and vertical welding, where vertical welding includes the vertical welding of two stainless steel pipe ports. Welding and vertical welding of one stainless steel pipe port relative to the side wall of the other stainless steel pipe. In the process of vertical welding of two stainless steel pipe ports, it is often necessary to cut the stainless steel pipe port in advance so that the port forms a welding port slope. In the actual welding operation process, manual alignment welding is generally carried out directly. Obviously, during the operation process, it is not convenient to quickly connect the welding ports of two stainless steel pipes, and it is not easy to ensure the accuracy of the ports being tightly fitted, which affects the accuracy of the butt joint. The connection strength and appearance of the final welded product
