Description of the invention (l) [Technical field to which the invention belongs] Infrared heating uses tungsten in the quartz lamp tube as a heat source to quickly heat the objects to be joined ;: due to kg = 2 outside line penetrates the quartz protection tube , And by appropriately focusing on: the line can be high rate), rapid cooling (fast heat dissipation) and the process with great development potential when joining. According to the present invention, a method for manufacturing a golf head by a combined process, A :: 2 :: "Bu line is quickly connected to the heat source heating method, heated and melted; = the outer line is between the strike surface of the Nanlf ball head Filling closure: containing m body t ;! golf head hitting surface to make golf ball :: golf ball head [prior art], the golf head is formed by joining the body and the hitting surface.

Joining of the description of the invention (2). The body material of the ball head includes non-recording steel, aging steel, titanium alloy, efficiency: = magnesium, gold, etc., and the material of the striking surface is titanium alloy, sisal ^ Shaped 5hex alloy, block amorphous alloy, etc. More common (= stainless steel (such as 17_4PH) golf body white = 2, bu 4 "hit, surface. This combination of golf head (^ 口 二, If the traditional brazing process is used, because the heating rate is low (^ -50 C / min), in order to reduce the exposure of the substrate to high temperature shadows [The working temperature is often set at the melting point of the brazing filler. Within its range, hold the temperature for another 10 ~ 30 minutes, and use the wetting effect between the hot liquid filler and the substrate to combine the two bases at both ends due to the hard Duo process at a relatively high temperature (Greater than 4 g 〇.〇), so a wide range of metallurgical reactions occur at = 3:!, Making part of the braze welding into the substrate, or because the elements in the substrate due to the high temperature environment, t Diffusion enters the filler alloy, thus changing the composition of the alloy, and L further affects the fluidity and wetting of the filler alloy. Wet and change the joint strength (called alloying, A1 loying). In addition, at the interface between the filler alloy and the material, a brittle intermetallic compound will be formed; if this limb / filler alloy / hitting surface The interface layer formed between them grows too thick, which will reduce the mechanical strength or impact resistance of the joint. This is also the reason why the dissimilar metals of golf heads are still mechanically embedded. / Mouth, and how to overcome the defects derived from the traditional brazing process described above, so that the joint between the dissimilar metals of the golf head can have better impact resistance, is the major

If the design is hard, it can reduce the brazing process; ί above, in order to improve the reliability of the contact . Force the joining process, you can :: occasionally make: other with rapid heating energy [Summary of the invention] To overcome the shortcomings of the traditional hard duo process. , "External work, springs have the reflection of light waves for ten years, so focus is used to increase the energy density of the infrared and enhance the mouth.), Consider two kinds of & the work / heart /, parabolic shape complaints (depending on the workpiece Morphology =) Applying gold treatment to the mirror surface and cooling with moderate cooling water = using eg = has better reflection effect, and is also suitable for higher temperatures :: ^. Infrared rays penetrate the quartz protection tube, and then focus on the heating area of the workpiece. During the entire process, the energy is used efficiently and avoids unnecessary waste. The infrared heating method has the characteristics of rapid heating and cooling: and greatly shortens the overall bonding time. Cheng. Compared with the traditional heating method (plus I: the rate is only about 5-5 (TC / niin), the infrared rapid bonding process has a rapid temperature rise and fall rate (up to SOOOt / min), so the substrate is exposed to during the bonding process The time in high temperature will be greatly reduced, and the possibility of adverse effects on the material due to high temperature will be reduced. In addition, coupled with the sensitive know-how control in seconds, the joint temperature will no longer be limited by the melting point of the filler. The above range is about 0 ~ 50 ° C, and the viewpoint of selecting the interface organization control is used to set a more appropriate working temperature. Therefore, in terms of production efficiency and control of process variables, the use of infrared rapid bonding It is better than the traditional hard ^ bonding process. 11 _ I II _ 1220116 V.

Description of the invention (6) " Hai weight block 20, the filled alloy 30 is first placed Between the golf head body 1 ^ and the weight block 20, the filling alloy 30 is heated by infrared rays to make the lens flicker.

To avoid alloying, the rate of infrared heating is preferably at least about 1 ° C / second, and more preferably about 50 ° C / second. The process parameters used in the wire bonding process such as: preheating temperature, upgrade rate, vacuum degree, process temperature and time are listed in detail in the third figure. f 'The heating process can be performed in the air.

For ^: ^^ For the purpose of ^ 丨-^ / "/ ^ — 'After the four contacts are exposed to infrared light at 1 00. 0, the cross section of the contact section is scanned by the scanning electron microscope (SEM) heat.

C: \ LOGO-5 \ five CONTINENTS \ PK9266.ptd Page 12 1220116 V. Description of the invention (7) EPMA chemical composition analysis data of each position in the surface. The figure can be roughly divided into a small amount of other metal regions (TiCu, η,%, Tic%) and residual filler regions in the Ti-Cii compound. It can also be found that the Cu atom in the filler reacts with the radical 4 and the Ag atom does not participate in the interface reaction. This will inevitably cause the Cu concentration in the filled alloy region to decrease and the relative Ag concentration to increase. Therefore, the primary crystal structure of Ag can be found in the two filled alloys in the sixth figure. This phenomenon can be reasonably explained simply from the phase diagram of the Ag-Cu binary alloy, that is, its composition line deviates from the original eutectic composition to the sub-eutectic composition. The seventh image is the infrared image. The increase in comparison time increases. This makes the filler have a larger size. Figure 8 shows that the joint strength value does not follow the potential. The strong phase is similar. SEM image of the cross section of the contact part under the condition of good speed is Π-6A, 4V / 72Ag-28Cu / 17-4PH contact under different speed heating joining conditions, six pictures and seventh It can be found in the figure that the thickness of the reaction layer between the filler alloy and the substrate will be increased with the heating temperature or holding temperature or extended. Under the condition of holding temperature of 30 seconds, because the holding temperature time is too short, the melting fails. It completely reacts with the substrate, which results in the existence of an Ag-rich eutectic structure on a two-to-one scale in the junction. ’Produced by I-6A1-4V / 72Ag-2 8Cu / 17-4PH at different infrared contact points. It is known from the figure that the maximum shear strength value ^ temperature 80 0 ° C test piece with a holding time of 20 seconds, the average shear height of about 96 · 4MPa. However, it can be observed from the figure that the joint strength / JDL increases with the increase of the day-to-day temperature or the temperature, but the trend of the decline is mainly due to the continuous growth of the interface. This result is compared with the aforementioned results using pure silver fillers. Lower bonding temperatures or shorter bonding times will result in stronger strength. This result is mainly due to the 72Ag — 28Cu filler and

Metallurgical reactions between T 4V or 17-4PΗ stainless steel substrates are suppressed due to the rapid heating process using the red wire. The third figure is the SEM image of the cross section of the Ti-6A1-4V / 95Ag-5A1 / 1 7-4PH contact after infrared bonding. It can be seen from the figure that the formation of intermetallic phase layer was not found in the residual filler area. The phase layer formed at the interface between the substrate and the filler is less than 1 # m and the chemical composition of EPMA is lower than the yoke envelope, so it cannot be determined accurately. The chemical composition of this phase layer was accurately and quantitatively separated out. The tenth figure is the contact shear test data of Ti-6A1-4v / 95Ag_5A1 / 17-4pH after infrared a is connected to a. Similar to the above two types of shear test results, because the use of infrared rapid heating process will be beneficial to suppress the formation of interface reaction layer, so using a lower bonding temperature will obtain a better connection. As can be seen from the above examples, infrared rapid bonding The application of the process will be suppressed. The generation of brittle compounds on the mouth interface will greatly improve these products. Two: the production efficiency and the reduction of energy consumption during the manufacturing process. Therefore, the cover technology can be widely used in the manufacturing process of various types of fillers to make golf heads, which is expected to help improve the quality and cost of such products.
