Welding Process of Fuel Tank Truck
CLVEHICLES.COM has a tank body welding process for fuel tanker truck. Many users who use oil tankers must also want to know how the tanker is made. Now I will introduce the welding of the oil baffle.
Welding of the oil baffle plate of the refueling truck: the main work is the welding of the oil baffle plate in the cylinder body. According to the above, three oil baffle plates are generally arranged inside the 6M long cylinder body, and the cylinder body is divided into four compartments. Each oil baffle plate The plate must be intermittently welded with the cylinder body. If it is a separate tank, the oil baffle will be replaced by a partition, and continuous welding must be carried out. The length of each girth weld is based on the aforementioned 6-7.5M length. The continuous welding is calculated according to half of the welding length. The total welding length of this station is about 20M, and the welding speed is calculated at 5mm/s. The welding time is about 67 minutes. Considering the poor welding conditions in the compartment and the different compartments The delay in welding preparation time, the multi-welding time of a single-section cylinder takes about 1 hour and 20 minutes, and 2 stations are needed for the calculation of a 12M long tank, so consider a station side by side as the oil baffle welding station.
Fuel truck tank docking: the main work is tank docking and TIG welding bottoming. If the small tank is not segmented, it can be used as a tank storage station. Tank body docking mainly depends on adjusting the position of the roller frame to align the tank body, so the length of the two tank body roller frame stations can be considered when designing the station. The welding speed of TIG welding is calculated according to 2.5mm/S. It takes about 50 minutes to join the circular seam of 7.5M. The docking takes about 2 hours, so consider a side-by-side double-roller station, and a 13M long station.

Head installation: The main work is head installation and TIG welding. Head alignment and butt welding require special tooling to ensure that the welding speed and workload are the same as the butt joint of the tank body mentioned above. According to the aforementioned TIG welding speed, it is estimated that the bottom welding of the head will take about 1 hour and 40 minutes. Considering the head The installation tooling ensures fast positioning. It is estimated that a single tank can be completed in about 2 hours and 40 minutes. Therefore, it is enough to consider a side-by-side double-roller station, and a 13M long station. Adopt two cans to work at the same time to ensure the working time. Because the installation of the head needs to lift the two sections of the head from the two sections, it is necessary to place the two sections of the station at a distance of 2M. Head welding and cylinder body welding are mainly for the grinding and repairing of the tank rotating frame on the tank body, the bottom welding of the cylinder body and the head butt joint ring seam, and the cover welding. According to the above, the circular seam is calculated according to 6~7.5M, and the cover welding speed is 5mm/s, and it takes about 1 hour to 1 hour and 15 minutes. According to experience, to achieve better welding quality, it is necessary to completely remove welding defects And grinding, so the estimated grinding time is about 40 minutes, plus the time for the tank to be hung on the tank rotating frame, the total time-consuming is about 2.5 hours, so a tank station is considered. And 13M long station. Adopt two cans to work at the same time to ensure the working time.
Installation of tank reinforcement plates: mainly used for the installation of all reinforcement plates such as longitudinal reinforcement strips, transverse reinforcement strips, and pipe box bracket reinforcement panels at the bottom of the tank. Generally, two longitudinal reinforcement strips are set at the bottom of the tank, and the size is about 0.4*12M; each horizontal reinforcement board is about 0.6*0.2M, and there are about 12 pieces within the length range of 12.5M; each tube box bracket has 2 pieces About 0.1*0.1M reinforcement plate, about 24 pipe box brackets, each tank body welding length is about 80M, considering that the workpieces in this station are scattered, each reinforcement plate needs to be marked and positioned, so it is arranged in this station Three welding machines work at the same time for spot welding of various reinforcement plates.
