Description

裂縫的修復方法及焊接結構Crack repair methods and welded structures

本發明是指一種裂縫的修復方法及焊接結構，特別是指一種具有彎折型修復路徑的超合金裂縫的修復方法及焊接結構。The present invention refers to a crack repair method and a welding structure, in particular to a superalloy crack repair method and a welded structure with a bending repair path.

在航太及能源行業中，部分組件會受到高應力及惡劣環境的腐蝕，所以選用鎳基超合金做為主體材料以抵抗該高應力及提高本身的抗腐蝕性。其中，鎳基超合金具有優異高溫應力特性及抗潛變能力。並且，一般意義上之鎳基超合金至少於700℃之條件下進行10000次的運作。業界製作鎳基超合金部件之方式是以鑄造形成為主，此方式可藉由調整冷卻速率、控制晶粒大小與成長方向。 此外，請參閱圖1，鎳基超合金部件7於精密鑄造時，容易因為冷卻速度控制不佳及模具設計的問題導致部件損傷、產生裂縫71或砂孔。因此，鎳基超合金部件7的裂縫71通常會使用焊條焊接 (例如： 氬焊、雷射焊接)的方法進行修補，且同時搭配焊前預熱來降低熱應力及減緩焊後的冷卻速度。然而，使用焊前預熱方式雖可降低修補區域之缺陷，但會大大提高鎳基超合金部件7的製作成本及降低整體產量(需花費額外的時間進行焊前預熱)。 因此，如何降低鎳基超合金部件的製作成本及提高整體產量，便是本領域具有通常知識者值得去思量地。 In the aerospace and energy industries, some components are subject to high stress and corrosion in harsh environments, so nickel-based superalloys are selected as the main material to resist the high stress and improve their corrosion resistance. Among them, nickel-based superalloys have excellent high-temperature stress characteristics and creep resistance. Moreover, in general, nickel-based superalloys should be operated at least 10,000 times at temperatures below 700°C. The industry's main method for manufacturing nickel-based superalloy components is casting. This method can control the grain size and growth direction by adjusting the cooling rate. In addition, please refer to Figure 1. When the nickel-based superalloy component 7 is precision cast, it is easy to cause component damage, cracks 71 or sand holes due to poor cooling rate control and mold design problems. Therefore, the cracks 71 of the nickel-based superalloy component 7 are usually repaired using electrode welding (for example, argon welding, laser welding), and are combined with preheating before welding to reduce thermal stress and slow down the cooling rate after welding. However, although the use of preheating before welding can reduce defects in the repair area, it will greatly increase the production cost of the nickel-based superalloy component 7 and reduce the overall output (additional time is required for preheating before welding). Therefore, how to reduce the manufacturing cost of nickel-based superalloy components and increase the overall output is something that those with ordinary knowledge in the field should consider.

本發明提供一種裂縫的修復方法，該裂縫的修復方法能降低超合金部件的製作成本及提高其整體產量。 本發明之裂縫的修復方法包括下列步驟： 首先，提供一焊接材料。之後，將該焊接材料沿著一彎折型修復路徑焊接於一裂縫上，以形成一焊接結構。其中，彎折型修復路徑包括多個第一路徑及多個第二路徑。該第一路徑是跨越該裂縫，且兩個相鄰的第一路徑相互重疊有一膜層重疊區域。此外，第二路徑是連結於兩個相鄰的第一路徑之間。 在上所述之裂縫的修復方法中，第一路徑的長度為2mm~50mm。 在上所述之裂縫的修復方法中，第一路徑的寬度為0.5mm~3mm。 在上所述之裂縫的修復方法中，第二路徑的寬度相同於該第一路徑的寬度，且該第二路徑的長度為該第一路徑的寬度之10%~70%。 在上所述之裂縫的修復方法中，第一路徑與該第二路徑的夾角為40度~150度。 在上所述之裂縫的修復方法中，焊接材料為鎳基金屬，且該鎳基金屬的鎳占比例為30%~100%。 在上所述之裂縫的修復方法中，鎳基金屬為英高鎳合金（Inconel）、蒙耐爾合金(Monel)、哈氏合金(Hastelloy)或MAR-M247鎳基合金。 在上所述之裂縫的修復方法中，焊接結構至少為一層，且該膜層重疊區域占至少30%的該第一路徑的面積。 在上所述之裂縫的修復方法中，焊接結構的厚度為0.1mm~5mm。 在上所述之裂縫的修復方法中，該裂縫位於一基板上，且該焊接材料在焊接於該裂縫之前，將基板加熱至200℃~700℃。 在上所述之裂縫的修復方法中，焊接材料是經由氬氣焊接方式、雷射熔覆方式或噴塗方式焊接於裂縫上。其中，該雷射熔覆方式的操作溫度為1200℃~1600℃。 本發明另一目的是提供一種裂縫的焊接結構，該裂縫的焊接結構能降低超合金部件的製作成本及提高其整體產量。 本發明之裂縫的焊接結構包括一焊接材料，焊接材料是沿著一彎折型修復路徑焊接於一裂縫上。其中，彎折型修復路徑包括多個第一路徑及多個第二路徑。第一路徑是跨越裂縫，且兩個相鄰的第一路徑相互重疊有一膜層重疊區域。此外，第二路徑連結於兩個相鄰的該第一路徑之間。 在上所述之裂縫的焊接結構中，第一路徑的長度為2mm至50mm。 在上所述之裂縫的焊接結構中，第一路徑的寬度為0.5mm至3mm。 在上所述之裂縫的焊接結構中，第二路徑的寬度相同於該第一路徑的寬度，且該第二路徑的長度為該第一路徑的寬度之10%~70%。 在上所述之裂縫的焊接結構中，第一路徑與該第二路徑的夾角為40度~150度。 在上所述之裂縫的焊接結構中，焊接結構至少為一層，且膜層重疊區域占至少30%的該第一路徑的面積。 在上所述之裂縫的焊接結構厚度為0.1mm~5mm。 本發明具有下述優點：經由焊接結構部分重複堆疊及來回往返的修復路徑保持被修復區域(裂縫及裂縫周圍之區域)之溫度，以同時達成修復及降低熱應力之目的。 為讓本發明之上述特徵和優點能更明顯易懂，下文特舉較佳實施例，並配合所附圖式，作詳細說明如下。 The invention provides a method for repairing cracks, which can reduce the production cost of superalloy components and increase their overall output.

請參閱圖2，圖2所繪示為本實施例之裂縫的修復方法的流程圖。裂縫的修復方法是適用於超合金製成的一部件8上，該裂縫的修復方法包括下列步驟。 首先，請參閱步驟S1，提供一焊接材料。其中，該焊接材料例如為鎳基金屬。並且，該鎳基金屬例如為英高鎳合金（Inconel）、蒙耐爾合金(Monel)、哈氏合金(Hastelloy)或MAR-M247鎳基合金。其中，該鎳基金屬的鎳占比例需為30%~100%。 接著，請參閱步驟S2、圖3及圖4，將該焊接材料沿著一彎折型修復路徑3焊接於一裂縫81上，以形成一焊接結構3W，且裂縫81是被焊接結構3W完全覆蓋。其中，該焊接材料是經由氬氣焊接方式、雷射熔覆方式或噴塗方式焊接於該裂縫上。其中，當使用該雷射熔覆方式時，其操作溫度通常為1200℃~1600℃。此外，該雷射熔覆方式所使用的雷射功率為300W~1500W，其雷射源頭的移動速度為0.5mm/s~15mm/s。另外，該雷射熔覆方式所使用的供粉氣體例如為氬氣，該供粉氣體的流速為1L/min~20L/min，且該雷射熔覆方式所使用的送粉速率為0.3g/min~10g/min。這樣一來，更有利於將該焊接材料焊接於該裂縫上。 上述中，彎折型修復路徑3是包括多個第一路徑31及多個第二路徑32，第一路徑31的長度為2mm~50mm，而第一路徑31的寬度為0.5mm~3mm，且在較佳的實施例中，所有的第一路徑31的長度皆實質相同，所有的第一路徑31的寬度也皆實質相同。也就是說，在扣除作業或其他因素所產生的誤差後，所有的第一路徑31的長度皆相同，所有的第一路徑31的寬度也皆相同。在本實施例中，第一路徑31為跨越裂縫81的焊接路徑，且所形成的焊接結構3W至少為一層，焊接結構3W的厚度為0.1mm~5mm。此外，在圖3及圖4中，為了有利於區分兩個相鄰的第一路徑31，所以兩個相鄰的第一路徑31的輪廓會分別使用虛線及實線表示。 請再次參閱圖3及同時參閱圖5與圖6，圖5所繪示為左方的第一路徑31與第二路徑32的夾角θ1的示意圖，圖6所繪示為第二路徑32與右方的第一路徑31的夾角θ2的示意圖。第二路徑32為未跨越裂縫81之偏移路徑，第二路徑32是連結於兩個相鄰的第一路徑31之間。其中，左方的第一路徑31與第二路徑32設有一夾角θ1，而第二路徑與右方的第一路徑31是設有一夾角θ2，夾角θ1及夾角例θ2如為40度~150度，且在較佳的實施例中，角度θ1是相同角度θ2。然而，在其他的實施例中，角度θ1也可不同於角度θ2。 另外，在本實施例中，第二路徑32的寬度是相同於第一路徑31的寬度，且第二路徑32的長度為第一路徑31的寬度之10%~70%。如此一來，兩個相鄰的第一路徑31便相互重疊有一膜層重疊區域31L，且膜層重疊區域31L是占至少30%的第一路徑31的面積。此外，兩個相鄰的第二路徑32同樣是相互重疊有一膜層重疊區域32L。因此，相較於傳統使用焊前預熱方式，本實施例之裂縫的修復方法經由部分重複堆疊(膜層重疊區域31)及來回往返的第一路徑31保持被修復區域(裂縫及裂縫周圍之區域)之溫度，便能達成修復裂縫81及降低熱應力。這樣一來，本案的修復方法還能間接降低超合金部件的製作成本及提高部件的整體產量。 在上述的實施例中，並未說明多個第一路徑31與多個第二路徑32是如何形成彎折型修復路徑3，以下將經由圖7至圖15來說明形成彎折型修復路徑3的過程。並且，圖7至圖15中的多個第一路徑與多個第二路徑會使用不同的符號加以區別。 首先，請參閱圖7至圖9，第一路徑311是跨過裂縫81，第一路徑311的尾端銜接第二路徑321的前端，第二路徑321的尾端再接回第一路徑312的前端，且第一路徑312再跨過裂縫81，並與左方的第一路徑311形成第一個膜層重疊區域31L。 之後，請參閱圖10至圖12，第一路徑312的尾端銜接第二路徑322的前端，第二路徑322的尾端同樣再接回第一路徑313的前端，第一路徑313再跨過裂縫81，並與第一路徑312形成第二個膜層重疊區域31L。接著，第一路徑313的尾端又銜接第二路徑323的前端。並且，第二路徑323與第二路徑321形成第一個膜層重疊區域32L。 再來，請參閱圖13至圖15，第二路徑323的尾端銜接第一路徑314的前端，第一路徑314再跨過裂縫81，並與第一路徑313形成第三個膜層重疊區域31L。之後，第一路徑314的尾端再銜接第二路徑324的前端，且第二路徑324與第二路徑322形成第二個膜層重疊區域32L。接著，第二路徑324的尾端銜接第一路徑315的前端，第一路徑315跨過裂縫81與第一路徑314形成第四個膜層重疊區域31L。然後，第一路徑315的尾端再銜接第二路徑325的前端，且第二路徑325與第二路徑323形成第三個膜層重疊區域32L。如此一來，裂縫81會完全覆蓋於多個第一路徑311、312、313、314、315之下，便形成所述的彎折型修復路徑3。簡單來說，該第一路經31與該第二路徑32是呈交錯之焊接路徑並重複多次，直到裂縫81處被焊接結構3W完全覆蓋為止。 此外，在圖7至圖15中，多個第二路徑321、322、323、324雖然沒有跨越裂縫81，但這些第二路徑321、322、323、324、325能確保彎折型修復路徑3成為一連續不間斷的焊接路徑。 上述中，部件8例如為一基板，裂縫81是位於該基板上。並且，若能在該焊接材料焊接於該裂縫之前，也就是執行步驟S2之前，先將該基板加熱至200℃~700℃，更能降低熱應力，還可減少被修復區域及部件8之間的溫度差，有效下降裂紋的發生率。 綜上所述，本發明之裂縫的修復方法及焊接結構透過部分重複堆疊及來回往返的第一路徑31達成修復超合金部件裂縫及降低熱應力，以間接降低超合金部件的製作成本及提高其整體產量。 Please refer to FIG. 2 . FIG. 2 illustrates a flow chart of the crack repair method in this embodiment. The crack repair method is suitable for a component 8 made of superalloy, and the crack repair method includes the following steps. First, please refer to step S1 to provide a welding material. Wherein, the welding material is, for example, nickel-based metal. Moreover, the nickel-based metal is, for example, Inconel, Monel, Hastelloy or MAR-M247 nickel-based alloy. Among them, the proportion of nickel in the nickel-based metal needs to be 30% to 100%. Next, please refer to step S2, Figure 3 and Figure 4, the welding material is welded to a crack 81 along a bent repair path 3 to form a welded structure 3W, and the crack 81 is completely covered by the welded structure 3W. . Wherein, the welding material is welded on the crack through argon gas welding, laser cladding or spraying. Among them, when using this laser cladding method, its operating temperature is usually 1200°C~1600°C. In addition, the laser power used in this laser cladding method is 300W~1500W, and the moving speed of the laser source is 0.5mm/s~15mm/s. In addition, the powder supply gas used in the laser cladding method is, for example, argon gas, the flow rate of the powder supply gas is 1L/min~20L/min, and the powder feeding rate used in the laser cladding method is 0.3g. /min~10g/min. In this way, it is more convenient to weld the welding material to the crack. Among the above, the bent repair path 3 includes a plurality of first paths 31 and a plurality of second paths 32. The length of the first path 31 is 2mm~50mm, and the width of the first path 31 is 0.5mm~3mm, and In a preferred embodiment, the lengths of all the first paths 31 are substantially the same, and the widths of all the first paths 31 are also substantially the same. That is to say, after deducting errors caused by operations or other factors, the lengths of all first paths 31 are the same, and the widths of all the first paths 31 are also the same. In this embodiment, the first path 31 is a welding path across the crack 81, and the formed welding structure 3W is at least one layer, and the thickness of the welding structure 3W is 0.1 mm~5 mm. In addition, in FIGS. 3 and 4 , in order to facilitate distinguishing two adjacent first paths 31 , the outlines of the two adjacent first paths 31 are represented by dotted lines and solid lines respectively. Please refer to Figure 3 again and refer to Figures 5 and 6 simultaneously. Figure 5 shows a schematic diagram of the angle θ1 between the first path 31 and the second path 32 on the left. Figure 6 shows the angle θ1 between the second path 32 and the right path. A schematic diagram of the included angle θ2 of the square first path 31. The second path 32 is an offset path that does not cross the crack 81 , and the second path 32 is connected between two adjacent first paths 31 . Among them, the first path 31 on the left and the second path 32 are provided with an included angle θ1, and the second path and the first path 31 on the right are provided with an included angle θ2. The included angle θ1 and the included angle θ2 are, for example, 40 degrees to 150 degrees. , and in a preferred embodiment, angle θ1 is the same angle θ2. However, in other embodiments, angle θ1 may also be different from angle θ2. In addition, in this embodiment, the width of the second path 32 is the same as the width of the first path 31 , and the length of the second path 32 is 10% to 70% of the width of the first path 31 . In this way, two adjacent first paths 31 overlap each other with a film overlapping area 31L, and the film overlapping area 31L accounts for at least 30% of the area of the first paths 31 . In addition, two adjacent second paths 32 also overlap each other with a film layer overlap area 32L. Therefore, compared with the traditional preheating method before welding, the crack repair method of this embodiment maintains the repaired area (crack and the area around the crack) through partial repeated stacking (film overlap area 31) and the first path 31 back and forth. The temperature of the area) can repair cracks 81 and reduce thermal stress. In this way, the repair method in this case can also indirectly reduce the production cost of superalloy parts and increase the overall output of parts. In the above embodiment, it is not explained how the plurality of first paths 31 and the plurality of second paths 32 form the bending repair path 3. The formation of the bending repair path 3 will be explained below through FIGS. 7 to 15. process. Furthermore, different symbols are used to distinguish the plurality of first paths and the plurality of second paths in FIGS. 7 to 15 . First, please refer to Figures 7 to 9. The first path 311 crosses the crack 81. The rear end of the first path 311 is connected to the front end of the second path 321. The rear end of the second path 321 is then connected back to the first path 312. The front end, and the first path 312 then crosses the crack 81 and forms a first film layer overlap area 31L with the first path 311 on the left. After that, please refer to Figures 10 to 12. The tail end of the first path 312 is connected to the front end of the second path 322. The tail end of the second path 322 is also connected to the front end of the first path 313. The first path 313 then crosses over The crack 81 forms a second film layer overlap region 31L with the first path 312 . Then, the tail end of the first path 313 is connected to the front end of the second path 323 . Furthermore, the second path 323 and the second path 321 form a first film layer overlapping area 32L. Next, please refer to Figures 13 to 15. The tail end of the second path 323 is connected to the front end of the first path 314. The first path 314 then crosses the crack 81 and forms a third film layer overlap area with the first path 313. 31L. Afterwards, the tail end of the first path 314 is connected to the front end of the second path 324, and the second path 324 and the second path 322 form a second film layer overlapping area 32L. Then, the tail end of the second path 324 is connected to the front end of the first path 315, and the first path 315 crosses the crack 81 and the first path 314 to form a fourth film layer overlap area 31L. Then, the tail end of the first path 315 is connected to the front end of the second path 325, and the second path 325 and the second path 323 form a third film layer overlapping area 32L. In this way, the crack 81 will be completely covered under the plurality of first paths 311, 312, 313, 314, and 315, thereby forming the bent repair path 3. To put it simply, the first path 31 and the second path 32 are staggered welding paths that are repeated multiple times until the crack 81 is completely covered by the welding structure 3W. In addition, in Figures 7 to 15, although the plurality of second paths 321, 322, 323, and 324 do not cross the crack 81, these second paths 321, 322, 323, 324, and 325 can ensure the bending type repair path 3 Become a continuous and uninterrupted welding path. In the above description, the component 8 is, for example, a substrate, and the crack 81 is located on the substrate. Moreover, if the substrate can be heated to 200°C to 700°C before the welding material is welded to the crack, that is, before step S2 is performed, the thermal stress can be further reduced, and the gap between the repaired area and the component 8 can be reduced.
