Ceramic welding pads are a kind of ceramic material with alumina as the backing, some people call it welding backing. It is a widely used ceramic material in welding process. It is mainly used to ensure the penetration of the root of the steel material joint and the formation of the back of the weld. It is a kind of backing device pre-placed along the back of the joint to force the weld to form an efficient, high-quality and low-cost welding method.

How to use ceramic welding pads, put the pads on the back of the groove of the shape and size specified by the steel plate and the workpiece, and weld from the front. It can form both sides at one time, and the back weld is full and the weld mark is neat. Ceramic welding pads are widely used in shipbuilding, steel structures, bridges, buildings, pipeline engineering, pressure vessels, chemical machinery, and metallurgical machinery manufacturing.
