Abstract

The invention relates to a method for preventing tin overflow in welding operation, in particular to a method for preventing a tin material from overflowing in the process of welding operation. The method comprises the following steps that: a butting sleeve is embedded and positioned in a bonding hole on a preset plate material through a weld part; the welding surface of the weld part is supported against the tin material on the outer rim of the bonding hole, and the bonding surface of the weld part is embedded in the bonding hole, namely a tin blocking casing body is closely matched in the inner hole to form close matching and embedding, and the tin blocking casing body is located to be prevented from generating axial displacement; a lateral edge surface of the tin blocking casing body is flush with the outer edge of the inner hole; when the butting sleeve and the preset plate material are welded in a reflow furnace, the tin blocking casing body prevents the tin material from overflowing into the inner hole of the weld part, and the deformation of the inner hole due to influence of welding temperature is avoided; and the tin blocking casing body exits the inner hole from the other side of the inner hole so as to complete tin overflow prevented welding operation.

Description

technical field [0001] The invention relates to a method for preventing tin overflow in welding operation, especially a method for preventing tin material overflow in the welding process. Deformation due to the influence of soldering temperature to complete the soldering operation to prevent tin overflow. Background technique [0002] General panels (board-to-board) are locked by positioning screws equipped with knobs, collars and screws when assembling operations, which fix the screws and collars on the first panel and turn them on the knobs. The screw is locked into the second panel to form a preset position, and then the screw is locked with a hand tool, so that the first panel is locked and fixed with the second panel as a whole, and can be used in a working machine or other board-to-board The board is used on the board for connection. [0003] However, with regard to the power device or the speed adjustment device of the above-mentioned working machine, they are all a...
