Overlaying welding babbit wire

Ingredient:

Sn,Sb,Cu

Application Fields:

Anti-friction characteristics of tin base babbitt and lead-based babbitt is only suitable for relative to the materials of low hardness, compared with the other bearing material, has better adaptability and pressure in the sex, organization characteristics, in the soft phase matrix uniformly distributed on the hard phase particle, soft phase matrix make babbitt has the very good embedded hidden sex, compliance and resistance to bite, and after running-in,The soft matrix is concave and the hard points are convex, so that a small gap is formed between the sliding surfaces, which becomes the oil storage space and the lubricating oil channel, which is conducive to reducing friction.The convex hard point plays a supporting role and is conducive to bearing capacity

Technical Support:

The surfacing welding of Babbitt bearing bush generally adopts TIG welding or MIG welding technology.

TIG (Tungsten Inert Gas Protection) welding technology is a high quality welding technology with low melting rate. The arc is burned between the tungsten electrode and the workpiece.Electrode does not melt, it is only as a current conductor and arc carrier, its principle is to use arc heat, under the protection of inert gas, the base metal or filler welding wire heating to melt state, brazing material at a certain speed to the base metal after pretreated surface, forming a weld or surfacing layer.MIG is a kind of TIG surfacing technology, brazing material instead of tungsten electrode, into the welding area for welding, the rest of the TIG surfacing technology is basically the same, MIG surfacing speed is faster than TIG, but the power supply control requirements are high.
