Taking aluminum and K4 glass as an example, the influence of process parameters on the welding process is analyzed. It is pointed out that how to reduce or eliminate the influence caused by the mismatch of thermal expansion coefficients between the two is the key of welding. The influence of welding temperature and voltage on welding And the influence of welding current. The optimum process parameters in this experiment range from 250 to 40 0 ℃ and 60 0 to 80 0V. At the same time, the mechanism of the combination was further explored. It was found that the glass and aluminum forms the transitional layer mainly composed of silicon, aluminum, oxygen, sodium and zinc in the anode welding process
