Connect and the phos copper for using argentiferous, red copper and ferrous metal are welded using phos copper, the phos copper of argentiferous, red copper and brass
Welding uses strong solder.
B. clean and smear solder flux
During welding, the part surface for being inserted into the contact of both pipe fitting and branch pipe is cleaned, and solder flux is applied to and is inserted into
On pipe fitting；
When branch pipe 4 and copper pipe weld, copper pipe End outer surface is cleaned first；
When branch pipe 4 and copper alloy weld, except cleaning end outer surface will also smear scaling powder；
When branch pipe 4 and stainless steel tube weld, filling with inert gas is carried out, prevents stainless steel oxidation, ensures welding quality；
Then pipe fitting will be inserted into insert in corresponding branch pipe 4, while the reducing among branch pipe 4 can control insertion depth.
C. the method for selecting heating
The heating of welding position has a variety of methods, new commercially available induction welding equipment can be used to heat, and can also use and pass
Acetylene-oxygen, liquefied gas-oxygen or the heating of other flames of system.
D. weld
（1）, using induction welding equipment when, induction coil is placed on to the position of the second annular groove 3, that is, inserts pipe fitting and branch pipe
The overlapping position of 4 grafting, when the temperature of branch pipe 4 and insertion pipe fitting reaches corresponding brazing temperature, such as at 600 DEG C -750 DEG C,
It is liquid that solder 1, which melts, now because capillarity, solder liquid infiltration are flowed into weld seam, natural cooling, observes weld seam matter
Amount, complete operation.
（2）, when being heated using flame, branch pipe 4 is heated to peony, it be liquid that solder 1, which melts, now due to capillary work
With solder liquid infiltration is flowed into weld seam, natural cooling, observes weldquality, completes operation.
The present invention with conventional brazing, receive sub- connection contrast it is as follows：

| Service life | It is long | It is long | Typically |
| Worker skill requires | It is low | It is high | It is high |
| Cost | It is very low | It is low | It is higher |
| Operability | Simply | It is complicated | Simply |
| Automatic production line can be adapted to | Energy | Difficulty is larger | Difficulty is larger |
| The sealed connection of copper and other metals can be realized | Easily | Difficulty is larger | Difficulty is larger |
| Whether naked light is had | There is no naked light during using sensing heating | It is | It is no |
The present invention can solve the welding of φ 2- φ 150 pipeline, make connecting pipe and the interface of pipe fitting to be connected completely close
Envelope, No leakage, intensity are high；And by setting welder, the requirement to operator's labour skill is greatly reduced, is reduced
The operation of upper welding rod, reduces labor intensity and complexity；And multiple weld bonds can operate simultaneously, facilitate factory automation to give birth to
Producing line welding copper pipe, copper alloy；The special pipe fitting of the present invention is simple to manufacture, and cost is low, and cost is well below receiving sub- connection side
Formula, it is simple in construction, it is easy to weld, can be widely applied to copper pipe and copper pipe, copper pipe and metal tube（It may need to change solder
Material）, copper pipe and other metal tubes welding.
