Sheet metal frame is a professional machine equipment mainly used for stamping, bending, forming, splicing and other processing work in sheet metal manufacturing. So, the editor of the sheet metal processing factory will talk about the following points to pay attention to during the welding process of the sheet metal frame:
1. Preparation work: Before starting welding, it is necessary to ensure that the sheet metal material meets the technical requirements and is free of defects such as cracks, pores, and slag inclusions. At the same time, clean the sheet metal materials to remove foreign objects such as oil stains, dust, and oxide layers to ensure welding quality.
2. Welding equipment and environment: Ensure that welding equipment and tools are in good condition and inspect their safety. During the welding process, maintain a clean and well ventilated environment to avoid fire and explosion hazards.
3. Welding operation: During welding, the dimensions and requirements on the drawing should be strictly followed to ensure symmetry, balance, and verticality of the welding. The welding surface should be clean and avoid the impact of oil and dirt on the welding quality. At the same time, choose appropriate welding methods, welding materials, and welding parameters, strictly control the welding heat input, and avoid deformation and welding cracks.
4. Welding quality inspection: After welding is completed, it is necessary to carefully inspect and test the weld seam, including its size, appearance quality, strength, etc., to ensure that the welding quality meets the requirements. If any unevenness or other problems are found in the weld seam, it should be repaired in a timely manner.
5. Safety protection: When carrying out welding operations, it is necessary to wear personal protective equipment such as masks, leather gloves, insulated shoes, etc. to prevent injuries caused by flying sparks and molten metal. Meanwhile, when welding in narrow areas, it is important to ensure that two operators rotate and monitor their safety at all times.
