Manufacturing process of large heads: rolling, turning, cutting
The material of the large head: Generally, 304 stainless steel and carbon steel are mostly used, but there are also special purposes, such as 310S material must be used for heat resistance, 316L material must be used for alkali resistance, etc.
The diameter of the head: the head should be stamped and formed with an abrasive tool. There will be some ground stress in the thick steel plate during stamping, and there will be relative deformation in the case of stamping and drawing, so how to distinguish the diameter of the head accurately. Whether or not, it all depends on what the diameter is and whether it is the norm.
Electric welding of large head and cylinder: In the case of butt welding of head and cylinder, the head and cylinder must be fixed with the average value of several points first, and then the electric welding is carried out uniformly.
