In order to make the head in the assembly welding, the welding seam should be far away from the corner transition zone with large tensile deformation when the head is pressed, so as to avoid the splicing welding line being damaged in the large deformation. For this purpose, It is stipulated that the welding seam splicing position of the head is limited to some extent. But after practice, it is found that this is not only waste material, but also cannot ensure the quality of welding seam after deformation.
Therefore, this restriction is no longer used. After the head assembly weld is formed, relevant tests should be carried out to ensure that it is consistent with the quality of the whole container. After the new application of the head standard, the welding seam splicing quality of the head is further improved, and the whole head is more intact.
