Aeriform protection solder efficient solder technical application as foreign technology introduce, by Jinan factory of the 2nd machine tool applied Φ above all 1981 1.

Technology of solder of protection of gas of CO2 of 6 solid core replaces American VERSON the Φ of company of compressor of complete steel machine 2.

Gas of rich argon of 4 medicine core protects solder technology, large to compressor weldment solders craft undertook tackling key problem, gain a success. This project won award of third class of achievement of progress of mechanical ministry science and technology. Factory of 2 machine tools applied Qiqihaerdi 1986 Φ 1.

Gas of rich argon of 2 solid core protects solder technology, solved compressor of large weldment solder problem, use technology of v of copper of filament argon arc, wait for v of layer of workpiece surface copper to piston, air cylinder, the copper that replaces our country tradition is covered score a success. Factory of the first machine tool applied Jinan first on the laminose case structural member in the machine tool 1992 Φ 0.

Gas of CO2 of 8 solid core protects solder. "During 75 " , factory of the 2nd machine tool returns Jinan to protected CO2 gas solder to use compressor the lengthen of taut bolt solders on, this project obtains " of industry of mechanical ministry machine tool achievement of 75 " craft is second-class award. Current, aeriform protection solder efficient solder technology, oneself is extensive the spare parts such as the pipeline flange that after applying at axis of machine tool lathe bed, gear, prejudicial body, rocker, cylinder body, solder, does not machine and case, oneself one of main technology that make machine tool industry solder. New technology of oscillatory effectiveness for a given period of time of 　 of application of technology of oscillatory effectiveness for a given period of time is 20 centuries the new-style engineering technology that 60 time development rises, this craft has applicability strong, managing the sources of energy, reduce environmental pollution, shorten production is periodic, increase the good point such as manufacturing efficiency. Jinan factory of the 2nd machine tool, began to use this craft promotion to the weldment that introduces a product 1981, obtained better result. Factory of machine tool of yellow stone v is in the research that " had development to craft of oscillatory effectiveness for a given period of time during 75 " and application, obtained " of industry of mechanical ministry machine tool achievement of 75 " craft is second-class award. Current, this craft got applied generally in machine tool industry. Solder the industry of applied machine tool of technology of automation, mechanization solders automation divides CO2 beyond semi-automatic solder, main body buries arc now on the application of automatic solder, the spells solder and pressure vessel cylindrical shell that basically uses at armor plate solders on. Jinan factory of the 2nd machine tool, through introducing American welding line to dog automatically the system was mixed 1993 solder power source, transformed the homebred and crossed crosshead that purchased 1988 to bury arc solder equipment automatically, realized 18mm cylindrical shell of thick the following pressure vessel, seal a head not to open groove butt joint double-faced and automatic dog the solder that bury arc, obtained garden to succeed completely. Solder mechanization, basically be to solder change the application of a machine, 1981 Jinan factory of the 2nd machine tool, solder in what introduce a product began to change on gear the applied research of a machine, but did not get popularizing, change this only a machine transformed gear the automatic cut equipment of spoke board. After 1988, solder change a machine is corresponding in factory of machine tool of v of mouth of factory of Shanghai v machine tool, battalion, Huang Shi factory of forging press bed got applied, rose to solder mechanization degree. Additional, limited company of group of 2 machine tools was in Jinan 1998 succeed in the collaboration of as small as Japan pine will change a machine apply at gear of 40GrMo tall alloy in soldering. Propane is efficient and energy-saving the liquefacient cut gas such as the applied propane of gas of environmental protection cut is the efficient and energy-saving environmental protection that 95 " of 85 " of national " , " extend gas.
