Description

Additional part that can be welded to a base part

The invention relates to an additional part, in particular a pot handle, that can be welded to a base part, in particular to an outer pot wall, wherein a welding projection or a welding projection is arranged on at least one of the two parts in the area of the welding point.

In the state of the art, for example, cooking pots made of stainless steel are known to which bow-shaped handles or handles made of stainless steel are welded. In the state of the art, this requires that the front surfaces of the handles are provided with welding bosses or welding projections. In particular, with such pot handles, it is problematic that the pot wall is rounded on the one hand and on the other hand runs at an angle to the vertical, so that the corresponding contact surface of the

Handle is rounded or bent on two axes. I

For this reason, the formation of a welding projection or a welding projection is very complex, since such projections can only be created by turning the material on the front surface of the handle part.

The consequence of this is that the handles made of stainless steel must be made of a steel that can be machined. For this purpose, an appropriate sulphur additive in the steel material is necessary. However, the sulphur additive reduces the welding quality and increases the susceptibility to corrosion, particularly in the welding area.

In addition, an exact fit against the pot wall is very difficult, if not impossible, to achieve.

Based on this state of the art, the invention is based on the object of providing a base part

to create a weldable additional part of the generic type, which is considerably easier to manufacture, easier to weld and, when using stainless steel, also less susceptible to corrosion.

To solve this problem, the invention proposes that the welding projection is formed by a separate weldable metal plate.

This makes it possible, for example in the case of pot handles, to adapt the corresponding contact surface of the handle precisely to the pot wall by creating two-axis curves through grinding.

Subsequent machining of the welding surface on a turning device is not necessary, as the material only needs to be ground and not turned.

The welding projection or welding projection is formed by a separate, punched plate, which is placed between the base** during the welding process.

part and the corresponding contact point of the additional part and melts when the welding current is applied, thus creating the connection. In this way, the three parts base part, additional part and metal plate are excellently connected to one another, with the metal plate completely melting during the welding process and then practically no longer being present as a physical object.

Preferably, it is further provided that the metal plate is attached to the welding surface of one of the two parts.

The attachment of the metal plate, preferably designed as a punched plate, to the ground surface, for example the pot handle or the pot wall, can be done by gluing this plate or attaching it in another suitable way. This attachment

Tacking or gluing only represents a temporary connection, which is only converted into a final connection between the individual parts after the welding process has been completed. The consequence of the design according to the invention is that, for example, any stainless steel can be used, whereby a sulfur additive for the purpose of machinability is not necessary. This also enables a higher welding quality to be achieved and reduces the susceptibility to corrosion in the welding area. A corresponding metal plate can, for example, consist of anti-magnetic stainless steel material with a thickness of 0.5 mm.

Preferably, the metal plate is welded to one of the two parts.

The metal plate can preferably be temporarily welded to the accessory part, in particular to the welding surface of the pot handle, in order to then

Subsequently, in the final welding process, the connection between the contact surface of the pot handle and the pot wall is created.

The invention is described below using a basic embodiment.

Opinion.

An additional part, in the example a pot handle 2, can be welded to a base part, in the example an outer pot wall 1. A welding projection or a welding projection is provided on at least one of the two parts 1 or 2 in the area of the welding point.

According to the invention, the welding projection is formed by a separate weldable metal plate 3, which, like the pot and the handle, can be made of stainless steel. The metal plate 3 can, for example, be 0.5 mm thick and have a diameter of a few millimeters.

In order to prevent the metal plate 3 from being lost before the handle 2 is welded to the pot wall 1, it is preferably provided that the metal plate 3 is attached to the welding surface 4 in the exemplary embodiment of the handle 2. This attachment can be carried out, for example, in such a way that the metal plate 3 is temporarily welded to the welding surface 4.

The invention is not limited to the exemplary embodiment, but is variable in many ways within the scope of the disclosure.
