Problems solved by technology

The corrugated sheet made in this way will be deformed and expanded after the test, which cannot guarantee the design requirements
Moreover, after the fuel tank is filled with oil, due to the expansion of the wave fins, the oil consumption is increased, which increases the cost
Therefore, when encountering large-sized corrugated sheets, especially photovoltaic and wind power substations, in order to avoid risks, most of them use sheet radiators, which increase the cost. poor effect

Embodiment Construction

[0012] A method for spot welding corrugated sheet stiffeners of a corrugated fuel tank, the specific requirements are: using a long-arm welding machine, after adjusting the voltage and air pressure, the corrugated sheet 1 and the 2 stiffeners are pressed and formed, every 40-50mm along the length of the stiffeners. Carry out spot welding, spot welding position 3 such as figure 1 As shown, complete the spot welding of the corrugated sheet stiffeners of the corrugated fuel tank.

[0013] A single-point long-arm welding machine can be used to perform spot welding at intervals of 40-50 mm. A multi-point automatic welding machine can also be used to perform spot welding every 40-50 mm.

[0014] The invention uses the multi-spot welding process at the reinforcing rib to solve the problem of mechanical strength. After using the method, the wave fins are not deformed, and can withstand the mechanical strength of 50kPa, which is far greater than the national requirements; at the same ...

Abstract

The invention discloses a spot welding method for a reinforcing rib of a corrugated sheet of a corrugated oil tank. The spot welding method specifically comprises the steps that a long arm welding machine is adopted, after voltage and air pressure are adjusted, spot welding is conducted at the reinforcing rib, formed through pressing, of the corrugated sheet in the length direction of the reinforcing rib at the interval of 40-50 mm, and then the spot welding of the reinforcing rib of the corrugated sheet of the corrugated oil tank is completed. By the adoption of the spot welding method, a corrugated wing will not deform and can bear the mechanical strength of 50 kPa which is far larger than a nationally regulated value, the oil injection amount can be reduced, and the problem that the oil tank leaks oil can be solved.

Description

technical field [0001] The invention relates to a corrugated sheet of an oil tank, in particular to a method for spot welding a reinforcing rib of a corrugated sheet of a corrugated oil tank. Background technique [0002] When the corrugated sheet of the corrugated tank is larger than 220mm, 1-2 reinforcing ribs should be pressed. After the tank is assembled, a mechanical strength test with a positive pressure and a vacuum of 30kPa should be carried out, and the duration should be 30min each. The corrugated sheet made in this way will deform and expand after the test, and the design requirements cannot be guaranteed. Moreover, after the fuel tank is filled with oil, due to the expansion of the wave fins, the amount of oil used increases, which increases the cost. Therefore, when encountering large-sized corrugated sheets, especially photovoltaic transformers and wind power transformers, chip radiators are mostly used in order to avoid risks. poor effect.
