CO_2气体保护焊在超高结构现场焊接中的应用

On application of CO_2 gas shield welding in field welding of super-high structure

通过CO2气体保护焊与焊条电弧焊在同等条件下的焊接对比试验、焊接工艺试验对比,结合现场施工情况对CO2气体保护焊的优劣影响进行了综合分析,指出CO2气体保护焊在野外超高结构现场焊接中有推广应用的价值。

According to the welding comparison tests of CO2 gas shidd welding and shielded metal arc welding with the same conditions, the paper compares the welding craft tests, and has the comprehensive analysis of factors which influence the advantages and disadvantages of CO2 gas shidd welding on the field construction, and points out it is valuable to extend the application of CO2 gas shidd welding on open-air super- high structure welding.
