Detail
There are 7 factors that affect the effective power output of the used high frequency welded pipe machines. Below we will introduce in detail according to these 7 factors, respectively, ①The V angle of the welded pipe. ②The shape of the two welding surfaces of the welded pipe. ③The distance between the solder joint and the center of the squeeze roller. ④ Welding temperature. ⑤The size, size, location and cooling method of the impedance device (magnet rod array). ⑥The physical characteristics of the steel pipe itself, such as diameter, wall thickness, material, etc. ⑦The design of induction coil.
① For welding V angle. the most economical and efficient angle is between 2-3°. In addition to electromagnetic induction heating, the main principle of high-frequency welding has two important effects, namely skin effect and proximity effect. The smaller the welding V angle, the more conducive to the proximity effect, so that the welding machine can be used more effectively. Effective output power.
②The shape of the two welding surfaces of the welded pipe is preferably that the two surfaces are parallel. which can make the welding more effective and the molecular diffusion between the two surfaces more uniform.
③The distance between the solder joint and the center of the squeeze roller. The best distance is the distance Lv=Lc marked in the figure below, and the length of Lc is close to the diameter of the steel pipe, which effectively reduces the welding current and improves the efficiency more effectively. (See below)
④ Welding temperature. The welding temperature plays a decisive role in the welding process. If the temperature is too high, the soldering surface will be melted, and if the temperature is too low, the solder will be weak and the solder will be weak. This requires an experienced "modulator" at the production site to make judgments based on experience. You can also install a temperature sensor at the upper end of the weld to feed the measured temperature directly to the main operating system of the high-frequency welder. Perform program analysis to automatically adjust the output power and adjust the temperature of the weld.
This system can automatically control the power of the used high frequency pipe welding machines according to the welding seam temperature. The pipe production quality is extremely stable, the energy-saving effect is obvious, and the production efficiency and the degree of automation have been greatly improved.
The above are the 7 factors that affect the effective power output of the used high frequency pipe welding machines. We can eliminate hidden dangers based on the impact of these seven factors on the effective power of the used high frequency pipe welding machines.
