Embodiment Construction

[0022] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.

[0023] Such as figure 1 Shown, the motor vehicle plastic part welding method of the present invention comprises the following steps:

[0024] Step 1: Determine the material of the base material and select the electrode; before completing the shaping process and entering the welding process, first determine the material of the plastic to be welded, and select the appropriate electrode according to different materials and welding requirements.

[0025] Step 2, surface treatment, in order to fully ensure the welding quality, the physical or chemical treatment performed on the surface of the plastic to be welded.

[0026] Step 3, welding seam positioning. Generally, the welding seam positioning is done before the formal welding. After the welding seam position is adjusted accurately, the ba...

Abstract

The invention discloses a welding method for a plastic part of a motor vehicle. The welding method includes the following steps that firstly, a base material is determined and a welding rod is selected; secondly, surface treatment is conducted; thirdly, a weld joint is positioned; fourthly, a groove is machined; fifthly, welding parameters are selected and a welding gun is adjusted; sixthly, welding operation is implemented; seventhly, the strength is evaluated, if the strength is enough, the ninth step is executed, and if the strength is not enough, the eighth step is executed; eighthly, a screen mesh is planted in; ninthly, the weld joint is processed; and tenthly, the weld joint is inspected. The welding method improves the strength and has a good welding effect.

Description

technical field [0001] The invention relates to a welding method, in particular to a welding method for motor vehicle plastic parts. Background technique [0002] Plastic parts are used more and more in modern automobile bodies, and the proportion of damage caused by these plastic parts in car collision accidents is very high. In addition to deformation, their damage forms generally include scratches, cracks, cracks and cracks on plastic parts. perforation etc. [0003] In the repair process of this kind of damage, in order to achieve the effect of repair as new, plastic welding technology is often used, so the welding process of plastic parts is an indispensable and important link in the repair process of automotive plastic parts. The existing plastic welding technology has the following problems: the air bubbles in the welding process are easily trapped in the weld seam, resulting in reduced strength and poor welding effect. Contents of the invention [0004] The techn...
