To raise the solder deliver a child of business of our country industry to produce efficiency is mixed solder technical level, hot be in harmony of treasure of Zhuhai city gold solders technical limited company overcomes Lu Si from world-renowned Germany (CLOOS) the company introduced TANDEM high speed efficient solder technology, popularize application energetically in home. In 10 years of in the past CLOOS offers an user to exceed 1000 Tandem to solder system. Now already many 100 TANDEM solders the system is used in home. Craft of TANDEM of use Ke Lusi solders when 2 -3mm thin plate, solder speed can amount to 6m /min, solder 8mm above is thick board when, frit apply efficiency can amount to 24kg /h, soldering is the optimal craft that replaces the solder that bury arc when the material such as the steel of low alloy excel in of energy of requirement control line. This craft can solder all sorts of metal stuff such as carbolic steel, low-alloy steel, stainless steel, aluminium, it is a kind of high speed efficient, application is wide advanced solder technology. Because have very tall solder speed, so this kind can solder only in machine support of the people automatic on can come true. One, TANDEM solders systematic principle: Ke Lusi company is at the beginning of 70 time use welder of double silk MIG art, company of 90 time Ke Lusi develops Tandem welder art. See graph 1, can see two kinds solder of craft differ basically. Solder in Tandem the spray head that uses two independence and two independent power source, every electric arc has what he becomes independent to solder parameter. And common double silk solders craft is two welding wire it is to use same soldering parameter. Graph 1: Tandem solders because craft principle solders new development reachs power source technology to solder very well the effect, solder in 90 time Tandem craft was replaced common double silk solders system. Solder to Tandem and character, important is two welding wire can use pulse electric arc, this offerred sufficient condition to use different pulse frequency to solder to the user, see graph 2. The plan differs a few kinds of the pulse weaveform that 2 Tandem solders assorted type: A) be the same as phasic B with frequency) with frequency phasic poor random is adjustable C) different frequency is phasic and aleatoric 2, the craft characteristic of solder of TANDEM double silk: 1, high-powered welder, 100% of short duration carry when rate solder voltaic 1000A, 1500A of pulse electric current; Power source of double pulse of 2, digitlization, 6 inches of LCD show, but process designing, join PC, printer; The normative parameter of every 3, welding wire but separate set, qualitative material, diameter can differ; The speed sending silk of every 4, welding wire can amount to 35m /min; 5, increase frit spread greatly efficiency and solder speed; 6, when frit apply efficiency increases, maintain inferior hot input; 7, electric arc is stable, frit drop transfers controlled; 8, solder be out of shape small; 9, splatter small; 10, solder data monitoring and management, wrong code shows; Gas of 11, use standard, air consumption is little; 12, scope of application is wide, productivity is tall. 3, MIG/MAG monofilament solder and TANDEM application compare: MIG/MAG monofilament solder and TANDEM application are shown respectively quite at the watch 1 with the graph 3. Solder of monofilament of watch 1 MIG/MAG and TANDEM application compare product name to solder material of methodological car gasoline tank: Aluminium board is thick: Type of 2mm welding line: Build receive, annulus seam welding seams ply: 2.
