In order to meet the above requirements, the following measures need to be taken when performing aerospace welding:

◆  der to meet the above requirements, the following measures need to be taken when performing aerospace welding:

◆  Select appropriate welding materials and processes: The aerospace field requires welding materials with high strength, good toughness, and strong corrosion resistance, so it is necessary to select appropriate materials and processes according to specific requirements.

◆  Carry out strict surface treatment: Before welding, the surface of the workpiece needs to be strictly treated to ensure that there is no oil stain, oxide scale, etc. on the surface before welding.

◆  Ensure the welding environment is dry: During the welding process, it is necessary to ensure that the welding environment is dry to prevent the generation and inhalation of hydrogen, thereby avoiding the occurrence of hydrogen-induced thermal cracks.

◆  Control the welding temperature and rate: For different materials and different processes, it is necessary to choose the appropriate welding temperature and rate to avoid problems such as weld cracking caused by too high temperature and too fast welding rate.

◆  Reasonable welding seam design: When performing aerospace welding, attention must be paid to the rationality of welding seam design to avoid welding seams that are too small or too complex, which is not conducive to the implementation of welding and the assurance of welding quality.
