Inc. of Changchun track coach (the following abbreviation grows a customer) it is passenger car of business of national emphasis mainstay, railroad and city track coach homebred change research and development and production base. Chief objective is mixed as railroad passenger car and research and development of city track coach the development of production technology, solder the development that the application of new technology also has advance rapidly. Chief objective goes up in the foundation of car of original carbon steel, already developed a variety of new products such as aluminium alloy car and stainless steel car now, form dimensions to produce. This and solder the development of new technology and application are not assigned. Below brief solder introducing that what chief objective applies new technology. Solder new technology produces the car of applied stainless steel that go up to have weight in stainless steel bodywork light, service life is long, workmanship is simple, need not lacquer, upkeep costs is low characteristic. The stainless steel that orbit car uses basically is the stainless steel of a few kinds of austenite such as SUS304 and SUS301L. Bodywork the intensity of steel structure tall, stiffness is good, realize bodywork easily light quantify. Steel structure is bodywork to solder completely profiled bar and board bridge construction. Stainless steel bodywork produces application to solder craft has: Solder of spot welding, seam welding, laser beam welding, MIG, TIG solder, small bundle of plasma arc solder and manual arc welding. MIG solder, TIG solder and small solder of bundle of MIG of plasma arc solder, TIG solder and small the craft such as bundle of plasma arc solder applies in the production in stainless steel bodywork a lot of, basically be manual solder and handiwork semi-automatic solder. Of application solder material is 308L and 309L, welding wire diameter 1.

0mm and 2.

0mm. Protective gas is argon - oxygen mixture gas and argon are angry. Solder power source of pulse of inversion of type of facilities use number, 350A of rated electric current. Solder new technology produces the bodywork of applied aluminium alloy that go up to have weight in aluminium alloy bodywork light, anti-corrosive, exterior flatness is good, make bodywork of complex curved surface easily. Be carried sectional welcome thereby by company of transportation of world each city and railroad, aluminium alloy bodywork is used on urban orbit car not only, and make in traffic of high speed railroad on the characteristic that has other material to cannot be replaced, accordingly, the foreground sex of aluminium alloy bodywork is first-rate. Aluminium alloy bodywork designs a structure to basically have two kinds of forms, namely board bridge construction and shut type hollow profile structure. Aluminium alloy bodywork solders aluminium alloy is one of solders the hardest material in all metals. Solder goodly the fund with quality need bigger investment undertakes Training Within Industry and equipment, tool is thrown. Aluminium alloy bodywork basically uses MIG solder technology. Assure to solder to reduce personnel cost to reach quality, aluminium alloy bodywork suits automation to solder more. Aluminium alloy bodywork solders to be divided normally for bodywork automatic solder mixes large part to always comprise automatic solder, automatic solder points to large part commonly car roof, floor is automatic automatic solder, chassis and roof reach solder, side bar side wall is automatic solder, always comprise automatic solder to show side wall and roof, side wall and chassis join seam automatic solder commonly. Small part solders in, the crucial part such as corbel often also uses manipulator to undertake soldering. Aluminium alloy bodywork makes the investment in building large key solders equipment and equipment, it is the essential condition of bodywork of production aluminium alloy. Solder new technology is in bodywork of steel of carbon of carbolic steel bodywork is board bridge construction. Of carbolic steel bodywork solder to basically use gas to protect solder technology, basically be manual solder and semi-automatic solder. Solder material is ER44-8 and ER50-6, welding wire diameter 1.

2mm. Protective gas is argon - carbon dioxide mixes air. Solder equipment is rated voltaic 500A or 350A. Only roof has to solder robot. Solder new technology is in the applied bogie on bogie production solder structure, group of bogie structural frame is become " H " model structure, armor plate material is S355J2G3 K20409 or 16MnR character. Solder to basically use gas to protect solder technology, basically be automatic solder and semi-automatic solder. Solder material is ER70S-6 and ER50-6, welding wire diameter 1.

2mm. Protective gas is argon - carbon dioxide mixes air. Solder equipment is rated voltaic 500A. Bogie solders 15 solder robot. CNC Milling
