Paper Title:
Study on Copper and Copper Alloy’s Manual SHS Welding Technology
  Abstract

Copper and copper alloy’s manual self-propagating high-temperature synthesis (SHS) technology was introduced in this paper. Through research of weld and analysis of manual SHS welding process, mechanism of copper and copper alloy’s manual SHS welding is expounded. This type of weld rod was only operated in terms of some welding technology, including welding method, weld technique parameter, weld operate. The chemical compositions of the weld rod was the key to the final weld quality. The powders include thermit, slagging elements and alloying addition. When the content of (CuO+Al) was 60%wt~80% in the thermit, the rod showed excellent combustion behavior and the test plates H62 were welded successfully.The slag system of CaO-Al2O3-SiO2 have the lower melting point and high deformation power, which fit to meet the need of the weld slag system of copper and copper alloy’s manual SHS welding. The high melting point Al2O3 can be digested and absorbed in two ways, generating CuO·Al2O3 ceramics and reducing the melting point to float upward into slag with the help of the solvent.
