Common problems in the manufacturing process of composite steel plate containers: What are the specific requirements in terms of materials, welding, non-destructive testing, heat treatment, hydrostatic testing, etc., compared to carbon steel?

How is the composite panel bonded in a composite steel plate container? For example, the outer layer is carbon steel, with SS316LL composite on the inside
The common processing methods for the composite layer of composite steel plates include: 1. Explosive bonding, 2. Rolling bonding, 3. Cladding bonding. For composite steel plates used in pressure vessels, explosive bonding is usually the method of choice. The relevant standards are: 1. GB8165-87 \"Stainless steel composite steel plates\", 2. JB4733-1996 \"Explosively bonded stainless steel composite steel plates for pressure vessels\". For reference!
When welding composite panels, it is essential to weld the base layer last to ensure that its basic properties are not compromised.
On the upper floor, in a regular mezzanine, welding is done last. During welding, it is carried out in a base layer, a transition layer, and a cover layer. Avoid the metal from the base layer from being incorporated during welding the overlay.
There are various processes suitable for blasting: heat treatment after compounding, and leveling
For composite panels, it is necessary to check the adhesion between the base layer and the composite material, as well as to inspect whether the composite material is contaminated. A certain amount of edge material must be removed from around explosive composite panels.
Reply to 4# taoyj: Should the lamination be welded last?
Pay attention to the fit rate, as well as the welding of the base layer, overlay layer, and transition layer – these are the key points
