SEAM WELDING SYSTEM MACHINE

• Use and Description of the Equipment

1. The equipment is for seam welding the lap seams between the corrugated top plates and corrugated chassis floors.
2. The equipment is in two sections: the welder and the worktable. Jobs are fixed and the welder will move.
3. It can be easy to operate, safe and reliable to use, easy to maintain and repair.
4. The seam welder shall be furnished with enough strength and rigidity. It shall be able to guaranteestable technical performances when working for 16hcontinuously.
5. Material for seam welding (spot welding): SUS301L and SUS 304 stainless steel.
6. Plate thickness: max. 2.0+2.0 mm, min. 0.6+0.6, effective longitudinal work range 26 m.
7. Production program: 8h/shift, 1 car/shift (total length of weld seam about 200 m).
8. The noise of the equipment shall not be more than 70 dB.
9. Welding standard: The acceptance standard for quality of welded points for spot welding will follow Japanese standard JISZ3140-1989 (Way for Checking the Spot-welded Places) and JISE4049-1990 (Way for Design of Welded Joints of SS Plates for Rolling Stocks).
10. The dimensions, e.g. relative heights, etc. of each part of the equipment shall meet ergonomics.

• Process flow:

        Two corrugated plates are placed on the worktable; the fixture clamps at two ends the      

       lapped corrugated plates; tack welding is first done, then continuous seam welding is done,

       or continuous seam welding is done directly.
