Embodiment Construction
[0021] A welding method for a titanium alloy golf head with a self-fusing edge. When processing the mold, the body part of the golf head mold is reserved with a height of 1.0-1.4mm, a width of 0.2-0.5mm, and a width of R angle of 0.5mm. In this way, the required self-fluxing edge can be formed during pouring; the height of the self-fluxing edge is 1.0-1.4mm, and the width of the self-fluxing edge and the ball head body is 0.3-0.5mm. The width of the R angle where the outer surface meets the self-fusing edge is 0.5mm.
[0022] Take a forged face panel made of titanium alloy, insert it into the face frame of the titanium alloy golf head with self-fusing edge, and then clamp it to the fixture of the MIG / MAG welding machine, use it with the self-fusing edge Welding forgings suitable for the self-fluxing edge of the titanium alloy golf head on the side, adjust the gap between the forged striking surface and the ball head body to make it consistent with the trajectory of the welding...

Abstract
The invention discloses a welding method and a casting of a titanium alloy golf club head with a self-fusing edge. The welding method is characterized in that the self-fusing edge with height of 1.0-1.4mm is reserved on the body part of the casting of the titanium alloy golf club head; the joint width of the self-fusing edge and the head body is 0.2-0.5mm; the width of the R angle of the joint part of the outer surface of the golf club head and the self-fusing edge is 0.5mm; the welding forging suitable for the self-fusing edge of the golf club head is used for welding; the width of the weld bead is not less than 4mm during MIG / MAG welding; and the current is controlled to ensure the penetration amount to reach 1.3-2.5mm. After the invention is applied, the distance between the shrinkage cavity of the self-fusing edge and the Face frame is reduced from original 1.5mm or so to 0.5mm or so, during the width of the weld bead being more than 4mm and complete penetration, the shrinkage cavity is remelted and is filled by the welding flux of the self-fusing edge, thus no shrinkage cavity is generated after grinding. The invention has good effects after popularization and application.
Description
technical field [0001] The invention relates to a titanium alloy processing technology, in particular to a welding method of a titanium alloy golf head with a self-fusing edge and a casting thereof. Background technique [0002] At present, golf heads are basically made of titanium alloy. The design of golf heads is becoming more and more complicated, and the wall thickness is getting thinner and thinner. This has caused many technical problems for casting technology. [0003] The face of the golf head is also called Face. In the past three years, most titanium alloy golf head face structures have become self-fusing edge structures. This structure replaces the manual feeding action in the welding process, making Standardization of operation has obvious advantages, but this structure has shrinkage cavities of 70% to 100% during grinding after welding, resulting in repair welding, and unevenness and other bad problems during repair welding, resulting in a high scrap rate , th...
