厚度在1mm以下的不锈钢薄板,用手工电弧焊的方法进行焊接时,不但成型不好而且容易烧穿。尤其是在焊接容器时焊接技术难度更大,不易掌握。现采用氧-乙炔焰焊法就很容易解决了,但应注意以下几个问题。一、焊前准备为了保证焊缝的理、化性能及改善焊接的可焊性,焊件的清理是很关键的一道工序。一般薄板件的焊接都不开坡口,接头型式多为对接、搭接及卷边焊。清理焊缝的最简单易行的方法就是用砂布将焊缝两侧20mm宽的接头清理干净,直到露出纯净的金属光泽,清理后要及时进行焊接。
Thickness of 1mm below the stainless steel sheet, the use of manual arc welding method of welding, not only bad shape and easy to burn through. Especially when welding the container welding technology more difficult, not easy to grasp. Now using oxygen - acetylene flame welding method is very easy to solve, but should pay attention to the following questions. First, the preparation before welding In order to ensure the management of the weld, the performance and improve the weldability, weldment cleaning is a key process. The general sheet metal welding is not groove, joint type mostly docking, lap and hem welding. The easiest way to clean the weld is to clean the joints 20 mm wide on both sides of the weld with emery cloth until pure metallic luster is revealed and the weld should be promptly cleaned after cleaning.
