Due to the demands of production, people have put forward higher requirements for the quality of elliptical head products, and at the same time, the competition in the market is becoming increasingly fierce. Based on the current application situation, elliptical head products have been widely used in many fields due to their excellent performance.

　　In fact, during the application of elliptical heads, for some pressure-free equipment, the requirements for them are generally not very strict. However, when applied to some high-pressure boiler equipment, there are clear requirements for both thickness and material. Especially the quality of the splicing welds must meet certain requirements to ensure safe use in the later stage.

　　Everyone should know that in the current market, since the size of steel plate raw materials is generally 1500 wide, when the size is large, it is necessary to carry out splicing treatment. So, when the elliptical head is being spliced, do you know what requirements should be met?

　　In response to this issue, first of all, the distance of the elliptical head splicing needs to meet certain requirements. This is because the heat-affected zone of welding is a high-stress zone, and the chemical composition in this zone will be burned off. When splicing, the direction of the weld seam is only allowed to be radial and circumferential. When two plates are joined together, the ends are chamfered and inclined to make it easier for the two plates to be welded through.

　　In addition, if the elliptical head is applied in some special occasions, 100% flaw detection treatment must be carried out on its weld seam. Therefore, extra care should be taken during welding. Generally, when using pressure vessel heads, it is necessary to provide a temporary inspection certificate for pressure vessels, a 100% non-destructive testing and flaw detection report, etc. In conclusion, when splicing the weld seams of the elliptical head, special attention must be paid. Moreover, after the splicing is completed, it must be ground smooth to make the appearance look more beautiful.
