2) link at described joint is provided with scolder, i.e. welding wire on described groove twines, and on described link outer wall coated with flux;
3) will be through step 2) joint handled is inserted in the described copper pipe;
4) use the described copper pipe of clamp, utilize the high frequency hypertherm to heat in the junction of described joint and copper pipe, the described scolder of fusion makes it full and uniformly soak into and fill seam between described joint and the copper pipe.
Above-mentioned high-frequency welding method drives described joint and copper pipe rotates continuously by described anchor clamps when utilizing high frequency hypertherm heating.
The described anchor clamps of above-mentioned high-frequency welding method are installed in the reducing motor rotating shaft, and drive rotation continuously by described reducing motor rotating shaft.
The induction heating circle of the above-mentioned described high frequency hypertherm of high-frequency welding method is for can be set in the circular of described joint and periphery, copper pipe junction.
The above-mentioned described induction heating circle of high-frequency welding method when heating, can pour into cooling water by hollow heat pipe coiled continuously in described heat pipe, prevent that described heat pipe is overheated.
Above-mentioned high-frequency welding method also comprises being provided with and drives and control device, starts or stops described high frequency hypertherm and described reducing motor by described driving and control device.
High-frequency welding method of the present invention utilizes high frequency heating machine to come heating and melting to be located at welding wire and solder flux on the chuck in advance, has replaced the technology of existing staff soldering, thereby has production efficiency height, welding quality stable, cost is low, labour intensity is low advantage; And because welding wire and solder flux are to be located at uniformly between joint and the copper pipe in advance, thereby when welding, welding wire and solder flux can be full and uniform soaks into and fills seam between joint and the copper pipe, has welding quality height, advantage that rework rate is low.In addition, when utilizing high frequency hypertherm heating, drive joint and copper pipe rotates continuously by anchor clamps, thereby make, welding wire and solder flux can be more full and uniform soaks into and fills seam between joint and the copper pipe, has improved welding quality, has reduced rework rate.
