Welding ceramic backing for shipbuilding

The core function of welding backing is: by pre-placing a backing device on the back of the weld, it ensures that the root is fully melted during welding and forms a back weld shape that meets the requirements, while simplifying the welding process. The specific functions can be summarized as follows: 1 2 Process optimization In single-sided welding scenarios (such as ship welding), it can replace the complex processes such as back root cleaning and back welding required for traditional double-sided welding, significantly improving efficiency. Taking ceramic welding backing as an example, its high temperature resistance (refractory>1500℃) can stably support the molten pool and avoid welding deformation. ‌Quality assurance‌ The prefabricated groove structure guides the flow of molten metal and controls the uniformity of the back of the weld (such as avoiding depressions or protrusions). Some backing materials (such as ceramic backings containing slag removal agents) can reduce the wo…
