introduction：By and large，Any part of the thermoplastic elastic system can be welded。however，It is not clear yet，What happens inside the weld of a thermoplastic elastomer。This isIK2Systematic research is carried out in the research topic。 Thermoplastic elastomer(TPE)，It has the advantages of both thermoplastics and elastomers，But its still a very immature material component。On the one hand, it can be processed like a thermoplastic；On the other hand，Over a certain temperature range，Finished product with thermoplastic elastic system，It has the characteristic of elastomer，But its not the same with elastomers，Waste or production residues can be reused，moreover
