Problems solved by technology

[0002] In the welding of penstock steel pipes in existing hydropower stations, especially in the welding production of large-diameter steel pipes, electrode arc welding is routinely used. In recent years, with the promotion and application of submerged arc automatic horizontal welding technology in other industries, the technology has gradually matured. Hydroelectric pressure steel pipes are rarely used. The welding of pressure steel pipes generally needs to go through welding process evaluation, productive welding tests, welding operator training and other links before it can be vigorously promoted and used in production. These processes are carried out separately according to conventional procedures. Process evaluation needs to make a special device, and the production test welding is basically carried out on the entire rolled steel pipe. If it is a single diameter and thickness, it is acceptable, but the production of pressure steel pipes in the hydropower industry has the following characteristics: 1. Different diameters and specifications ; 2. The material of the steel plate is complex, ranging from Q235, Q345, to 600MPa, 800MPa; 3. The wall thickness of the steel pipe is different, and the commonly used ones range from 20mm to 100mm

Abstract

The invention discloses a submerged arc horizontal position welding testing device which comprises a submerged arc horizontal position seam welder, a supporting rail and two supporting stand column mechanisms arranged on the supporting rail. Two testing plates matched with guide wheels of the submerged arc horizontal position seam welder are arranged between the two supporting stand column mechanisms. Both the two testing plates are curved-face testing plates or plane testing plates. A simulation rail used for guiding moving wheels of the submerged arc horizontal position seam welder to walk is arranged between the two supporting stand column mechanisms. The simulation rail is a curved-face simulation rail or a plane simulation rail. The simulation rail is located above the testing plates. A curved-face testing plate locking mechanism and a plane testing plate locking mechanism are arranged in the middle of each supporting stand column mechanism. A curved-face simulation rail locking mechanism and a plane simulation rail locking mechanism are arranged on the top of each supporting stand column mechanism. The submerged arc horizontal position welding testing device can achieve three different purposes of welding procedure qualification, production welding testing and welding operator training, effectively reduce cost, improve production efficiency and improve welding quality.
