Friction plug welding is a solid phase welding technique that eliminates the friction stir welding tail holes or defects with a consumable special plug. There are many advantages. Friction plug welding is a solid phase welding technique that eliminates the friction stir welding tail holes or defects with a consumable special plug. It has many advantages, such as: large depth and narrow gap welding; low cost of plug material; environmental protection; fast welding speed, filling holes of 100mm depth for only 20s; and welding in harsh environments. The welding process is as follows: under certain pressure or tension conditions, the plug rod drives the plug rod to rotate by the driving device, rubs with the interface of the plug hole (the hole to be welded), forms plasticized metal, and holds for a period of time to complete the welding.

Solid-phase synthesis, as the main process in the production of Bio-pharmaceuticals, is widely used for the synthesis of peptides, deoxyribonucleic acid (DNA) and so on. The synthesis method is to bound the functional group such as methyl on a bead, which primiarly is polystyrene microsphere with low crosslink.
To be the core basic material, the characteristic of the beads have a great influence on the properties of peptides and deoxyribonucleic acid to be produced.
