Welding is one of the necessary processes in the production process of imitative Rittal cabinet. To ensure the processing quality of this process, we should pay attention to the following points.

焊接前的准备工作：焊接劳动保护用品要穿戴整齐，对焊接设备、焊条等进行检查，是否符合规定要求，有无运转不灵的问题；焊件上的铁锈、油脂及水分等，应清除洁净。

Preparation before welding: the welding labor protection articles should be dressed neatly, and the welding equipment and welding rod should be checked to see whether they meet the requirements and whether they are not working properly; Rust, grease and moisture on weldment shall be removed and cleaned.

预处理焊缝坡口的底子尺度：焊缝坡口要合理，这样才能够确保尺度精度，以削减焊接变形

Basic dimension of pre-treatment weld groove: weld groove should be reasonable, so as to ensure the scale accuracy and reduce welding deformation

核准工艺参数：焊接的工艺参数，主要有焊条直径、焊接电流、焊接电压以及焊接速度等

Approved process parameters: welding process parameters, mainly including electrode diameter, welding current, welding voltage and welding speed

要充分了解焊接的结构：焊条应能够确保进入焊接区，并且要歪斜45度才行。在焊接时，不允许进行长焊缝接连焊接，应进行交替断续焊接，避免呈现热变形，影响焊缝的焊接质量。

To fully understand the welding structure: the electrode should be able to enter the welding area, and to skew 45 degrees. During welding, it is not allowed to carry out continuous welding of long welds, but intermittent welding should be carried out alternately to avoid thermal deformation and affect the welding quality of welds.
