Document Type and Number:
WIPO Patent Application WO/2018/092609
Kind Code:
A1
Abstract:
Provided is a method for forming a strap for a lead storage battery, with which it is possible to prevent occurrence of welding defects when forming the strap for the lead storage battery using a plasma welding device. As shown in a torch movement path 10, a torch of a plasma welding device is moved from a start point 10s in the Y-direction while weaving in the X-direction in which a single tab 1 inserted in a slit is defined as the center and the welding direction of the single tab is defined as the Y-direction. The meaning of weaving is to move the torch in the X-direction in an oscillating manner. This operation causes portions of the single tab 1, a base, and an added lead component to be fused, and this operation is performed on all of a plurality of tabs 1 so as to form a strap 9, whereby it becomes possible to prevent occurrence of welding defects due to insufficient fusing.
