Circumferential welding is the welding of various circular rings and annuli. The weld formed after welding is a closed circular ring. It is widely used in pipe-to-pipe welding, tube-to-sheet welding, pipe flange welding, etc. Circumferential welding can be divided into vertical circumferential welding and horizontal circumferential welding according to the position angle of the weld. Vertical circumferential welding is the radial vertical circumferential welding of pipe fittings, such as the butt welding of vertically placed pipes. Horizontal circumferential welding is the radial horizontal circumferential welding of pipe fittings, such as the butt welding of horizontally placed pipes.
Automatic circumferential seam welding technology is to carry out circular or annular welding through an automatic circumferential welding machine. It is suitable for high-quality welding of materials such as carbon steel, stainless steel, and titanium alloys, and can select argon arc welding (with or without wire filling), metal arc welding, plasma welding and other welding power sources to form a set of circumferential automatic welding systems. It can be widely used in the welding of hydraulic cylinders, gas storage cylinders, chemical and medical containers, liquefied gas tanks, rollers and liquid storage cylinders for mines and production lines.
According to the shape and size of the processed objects and the different welding angles, the automatic circumferential welding machine can be roughly divided into: vertical circumferential welding machine, horizontal circumferential welding machine, welding positioner, welding center, contour circumferential welding machine, etc.; the structure is mainly composed of frame, rotary mechanism, flip mechanism, conductive device, electrical control system and other parts. There may be some differences between the automatic circumferential welding machines of different manufacturers. Meihan automatic circumferential welding machine is professionally customized according to the actual needs of customers, and provides pre-sales, in-sales and after-sales welding technical support services throughout the process, one-to-one turnkey projects.
After Automatic Circumferential Welding, The Weld Can Be Inspected From The Following Aspects:
2. Radiographic inspection: Carry out finished product inspection according to the radiographic inspection process specifications, and judge according to the qualified standards of finished product inspection, generally level III is qualified. The actual radiographic flaw detection results must reach a qualified rate of 100% and a level I film rate of 98%.
3. Destructive test detection: general hydraulic blasting or mechanical property test, according to the national standard for welding joint test detection methods and projects to start detection verification and qualified judgment.
Advantages Of Automatic Girth Welding Technology:
1. Improve work efficiency: Automatic girth welding equipment can perform continuous and high-speed welding operations, which can greatly improve work efficiency compared to manual welding.
2. Ensure welding quality: Automatic girth welding equipment has highly consistent welding parameters and operating accuracy, which can maintain consistent welding quality in each welding and reduce the occurrence of welding defects.
3. Reduce labor costs: Automatic girth welding equipment can reduce the need for manual operation, thereby reducing labor costs, and can avoid welding quality problems caused by improper operation.
4. Improve safety: Automatic girth welding equipment can avoid the risk of personal injury in welding operations and improve the safety of the welding process.
5. Applicable to a variety of materials and products: Automatic girth welding technology can be applied to the welding of a variety of materials such as carbon steel, stainless steel, titanium alloy, etc., and can also be applied to the welding of different types of products such as hydraulic cylinders, gas storage cylinders, chemical containers, and liquefied gas tanks.
In general, automatic girth welding technology is efficient, accurate and reliable, which can improve welding quality and work efficiency, reduce costs and improve safety. This makes it widely used in modern manufacturing, and with the continuous development of technology, automatic girth welding technology will continue to be further improved and innovated.
