Abstract

The present invention provides a welded product which comprises a first element and a second element, and further comprises a third element, wherein the melting point of said third element is between that of the material of said first element and the material of said second element, one end of said first element is fixed into an accommodation space formed by said third element and said third element is welded onto said second element. It is made easy to weld together two parts to be welded by way of the medium effects of the third element, so that the welded product can meet the application requirements regarding mechanical strength and electric strength.

Description

technical field [0001] The present invention relates to a welding product, a welding method and a circuit breaker, and more particularly to a welding product and a welding method for welding using an auxiliary part, and a circuit breaker including the welding product. Background technique [0002] Today, as the field of low-voltage electrical appliances continues to develop, the use of thermal elements (such as thermal bimetallic strips or bimetallic elements) plays a very important role in the development of the entire field. Thermal bimetal is a relatively simple self-control element for temperature control, which consists of two layers of metals (or alloys) with different thermal expansion coefficients. The layer with a large expansion coefficient is called the active layer, and the layer with a small thermal expansion coefficient is called the passive layer. When the thermal bimetal is heated, the length of free expansion of the active layer is greater than that of the ...
