Description of the invention (1) The present invention is a kind of thin pipe body welded with an end face of a welded pipe. A high temperature is used to block the welded joints of two joint pipes. ? The inclined surface (61) (71), (6 0) (7 0) of the inclined pipe (60) and (7 0) of the special pipe body end connecting pipe (60) and the second connecting pipe (70) form an angle with each other. The joints of the inclined surfaces (6 1) (71) are welded by the first and second connecting pipes (60) (70), but the following problems are prone to occur: 1. The welds will have depressions, as shown in the eighth figure, Because the welded pipe wall is very thin, and the first and second joints form a hollow state inside, it is easy to cause depression and change the quality of the periphery of the weld. 2. The welded joints cannot be ground and polished, and they are dented on both sides of the weld bead. The flattened joints will result in the appearance quality of the welded joints. It is based on 'the inventor's understanding of the shortcomings', so that he can improve the existing shortcomings in welding products, and the welding method, in particular, to avoid the welding of thin-shaped welded pipes by welding. Fang Yutan then combined the first and second positions by one end to perform full-circle welding. However, the deformation of the first and second connecting pipes (60) (70) and other phenomena caused by welding are strict. Therefore, even though the obvious welding marks after research have been researched and developed with years of production and marketing with thin tube welding, a joint method produced when the two are connected. As shown in the seventh figure, the first cut is made into a butt joint pipe and then welded (40), so that the end of this type of welding side, the joint of the pipe (60) (70) is born. High temperature, bulk density affects the grinding of welding and can not make welding marks, and there are still many experiences influencing welding methods.

Description of the invention (3) (12) (22) Nozzle (20) (70) Second connection pipe (30) (31) Stretcher (40) Welding (41) Solder (6 7) Seam Please refer to the first figure, the present invention is a thin pipe body welding method, which is a method for welding the first adapter pipe (10) and the second adapter pipe (20) with a thin hollow wall. The method includes: wounds Material, sealing, welding, and then grinding and dragging to make the surface smooth, the detailed description of each step is as follows: Preparation: As shown in the second figure, 'the first connecting pipe (10) and the second connecting pipe (20) to be welded ) Respectively at the end of the joint, according to the joint angle needs to be cut into the opposite inclined surface (11) (2 1) ^ for use; sealing: as shown in the second figure 'and then the first connection has been cut The tube (10) has an inclined surface (11) at one end, and a stretcher (30) is embedded in the tube opening (12), and the second connecting tube (20) is also in the inclined surface (21) tube opening (22). One pound piece (31) is blocked. 'The two baffle pieces (30) (31) are the same size as the nozzle openings (12) (22) of the first and second connecting pipes (10) (20),' respectively. The stopper (30) (31) is separated by spot welding The first and second connection pipes (10) (20) are fixed together; welding: as shown in the third and fifth figures, the inclined surfaces (11) (21) of the first and second connection pipes (10) (20) Close together and fix it, and then use the welding gun (40) to spot weld the first and second joint pipes (10) (20) for preliminary welding, and then use the welding gun (40) along the first, The joints between the two joint pipes (10) (20) and the inclined surfaces (11) (21) are welded in a full-circle manner, so that the solder (41) penetrates into the joint
的縫隙並佈滿於管外周； D 研磨：如第五、六圖所示，由於第―、二銜接管（1〇 (20)焊接結合部位之焊料（41)呈條狀突起，為消除突起之 45 884 1 五、發明說明（4) 痕跡，故以研磨方式將突起之焊料（41 )磨平除去； 拋光：經研磨後之焊接部位雖具有平整之平面，但研 磨後粗糖痕跡十分明顯’為消除表面粗縫現象，故須再將 研磨後之表面作進一步拋光，使焊接部位之表面與第一、 二銜接管（1 0 )( 2 0 )表面一樣光滑； 再者，如第四圖所示’本發明亦可用於不需將第一、 一銜接管（1〇)(2〇)裁切成傾斜面之焊接方式，其焊接（匸） 前相同的將擋片（30)(31)嵌固於第一、二銜接管（1〇)(2〇) 坪接端之管口（11)(20)内，再使第一銜接管（;1〇)之端面貼 合於第二銜接管（2〇)之一側緣，並與其端面切齊（如第四 圖所示），然後將第一、二銜接管（1〇) ( 20)點焊固定，再 以焊搶（4 0 )沿第二銜接管（2 〇 )端面外周進行全周焊接，使 第一、二銜接管（10)(20)結合，最後再經研磨、拋光完成 焊接結合動作。 由於本發明於焊接前已於第 銜接管（10)(20)焊 接為邻之管口（12)(22)内分別嵌固有一擋片（3〇)(31)，使 第一:二銜接管（1〇) (2〇)焊接端之管口具有支撐力，因此 可有效支撐焊接時產生高溫所造成之凹陷變形現象，藉 t时並可於焊接後輕易磨除突起之焊料⑷），使焊接‘留 痕跡’而達提升薄管焊接品質之目的。 並未斤f ’本發明的確可改善習用薄管焊接之缺點， :德；Γ法提出申請，態請釣局賜淮本發明專利=The gap is covered on the outer periphery of the tube; D Grinding: As shown in the fifth and sixth figures, the solder (41) of the joint joint of the first and second connecting pipes (10 (20) has a strip-shaped protrusion, in order to eliminate the protrusion. 45 884 1 V. Description of the invention (4) Traces, so the protruding solder (41) is ground and removed by grinding; Polishing: Although the welded part after grinding has a flat surface, the traces of coarse sugar after grinding are very obvious' In order to eliminate the rough seam phenomenon on the surface, the polished surface must be further polished to make the surface of the welding part as smooth as the surface of the first and second connecting pipes (1 0) (2 0); further, as shown in the fourth figure As shown, the present invention can also be used in a welding method that does not require cutting the first and first connecting pipes (10) and (20) into inclined surfaces. The same method is used to weld the baffle (30) (31) before welding (匸). ) Is embedded in the mouth (11) (20) of the first and second connection pipes (10) (20), and then the end surface of the first connection pipe (; 10) is adhered to the second One side edge of the adapter pipe (20) is cut to the end face (as shown in the fourth figure), and then the first and second adapter pipes (1〇) (20) are spot welded Fix it, and then use welding (40) to weld the entire circumference along the outer periphery of the end face of the second adapter pipe (20), so that the first and second adapter pipes (10) (20) are combined, and then the welding and bonding are completed by grinding and polishing. Since the present invention has been welded with an inherent baffle (30) (31) in the mouth (12) (22) of the joint pipe (10) (20) adjacent to each other before welding, the first: The mouth of the two connecting pipes (10) (2) has a supporting force at the welding end, so it can effectively support the depression deformation caused by high temperature during welding, and it can easily remove the protruding solder after welding. ), So that the welding 'leaves' to achieve the purpose of improving the welding quality of thin tubes. It does not mean that the present invention can indeed improve the shortcomings of conventional thin-tube welding .: Germany; Γ method filed an application, please invite the fishing bureau to grant the invention patent =
