Standards for Main Chassis Welding in Sheet Metal Processing Factory

1. make welding according to drawings, technology and processing technology regulations of sheet metal manufacturers;

2. when welding, be sure to make grooves in the grooves. If there is no groove or welded contour, the groove should be polished according to the specific situation. If the groove must be produced, production processing should be carried out. And report the problem to the person in charge of the unit.

3. When welding, the form and position tolerance of the product workpiece should be guaranteed. Form and position tolerances for non-machined surfaces shall be in accordance with IT15 grades.

4. if the raw materials must be removed and replaced during the whole welding process, the wall thickness of the plastic plate cannot meet the requirements of the drawing, and cannot be removed and replaced without the permission of the written materials of the technical organization.

5. Welding during welding strictly follow the drawing regulations. Continuous welding in continuous welding and intermittent welding must be intermittent welding. If the size and length of intermittent welding as shown in the figure below are not used, the interval time of every 50mm is 8 to 10mm, and the spacing of each welding point must be symmetrical.
