(1)NC Seaming Machine：In accordance with the Imitating type mechanism harmonized with the NC servo system, the fuel tank (upper piece and lower piece) will be automatically seam-welded by the fringe of fuel tank.

(2)Spot Welding Machine : Before seam-welding procedure, the fuel tank (upper piece and lower piece) must be welded by Spot Welding Machine first in order to combine the upper piece and lower piece.

(3)Leaking Tester: After seam-welding process, the fuel tank must be checked and tested with this Leaking Tester.

(4)3-Phase DC Projection Welding Machine: the projection welding for the body of fuel tank and oil gauge stand. It is the rapid and efficient welding instead of traditional brazing.

(5)Double Housing 3-Phase DC Projection Welding Machine: It is the Three-in-One projection welding machine, which can process the following welding; (a) the oil gauge stand & the body of oil tank. (b) the inlet caliber of gas & the body of oil tank. (c) the outlet caliber of gas and the body of oil tank.

(6)Dual Gun NC Spot Welding Machine: the prevailing Spot Welding Machine which executing the welding for the oil gauge stand & the body of fuel tank.

(7)Horizontal Seam Welding Machine: this machine is manipulated manually, a simple model of Seam Welding Machine.
