Abstract

The present invention provides a welding device for metal structural components, comprising a heat-conducting fixed structure and a shell. The upper end surface of the shell is provided with four sets of empty grooves, and a conveying component is installed inside the shell. The upper end surface of the shell is fixedly connected with a feeding positioning component and a welding component. The feeding positioning component is used for positioning the metal structural component and conveying the welding material to the welding point. The welding component is used for welding the metal structural component. The present invention can increase the support area through the fixed edge and the sealing edge, thereby improving the stability of the fixation. When the metal structural component is fixed on the fixed component, the elastic lip edge one and the elastic lip edge two will seal the bonding point between the metal structural component and the bonding adhesive, effectively avoiding the overflow of the bonding adhesive. When the semiconductor condenser plate cools the adhesive, it can conduct cold conduction to metal structural components, Thus achieving cooling of metal structural components, the gap between the fixed edge and the adhesive will form negative pressure, further improving the fixing effect of the fixed components on the metal structural components.
