Problems & Solutions

問題和解決方案

As a manufacturer we pride ourselves in not only supplying the right product for the job but also ensuring that the correct methods of application are used before, during and after welding. Remember, If you are lucky enough to own a Ferrari, but put the wrong petrol in it, you can be sure it will not perform to its optimum.

作為一家焊材制造商，我們不僅為客戶提供正確的產品，而且確保在焊接之前、期間和之后使用正確的應用方法，我們為此感到自豪。請記住，如果你有幸擁有一輛法拉利，但放錯了汽油，可以肯定它不會發揮其正常性能。

1. Furnace Repairs - These applications can mean both the base material and the weld material may be subject to temperatures as high as 1400°c. As well as this inherent problem the weld will most likely need to withstand thermal cycling. It is with this in mind that MWA International Ltd usually recommends either our Mac Stain E102 or our Mac Nicro E215 for long term repairs.

熔爐維修 - 這些應用可能意味著母材和焊接材料的溫度可能高達1400℃。除了這一固有問題外，焊縫很可能還需要承受熱循環。考慮到這一點，MWA公司通常推薦我們的不銹鋼焊條Mac Stain E102或鎳合金焊條Mac Nicro E215進行長期維修。

2. Gears and Sprockets - When teeth are worn or broken on gears it is important that repairs achieve at least the equal life of the original component. It is not always necessary to use a hardened material, toughness is more important, as is the welding techniques to avoid heat build-up. Mac Trode E66 and Mac Cast E407 have the best characteristics suited to reclaim these types of repairs.

齒輪和鏈輪 - 當齒輪上的輪齒磨損或斷裂時，重要的是維修至少要達到與原始部件相同的使用壽命，并不總是需要使用硬化材料，韌性更為重要，因為焊接技術可以避免熱量積聚。MWA鎳鉻合金特種鋼焊條Mac Trode E66和鑄鐵焊條Mac Cast E407最適合修復此類部件。

3. Shot Blast Cabinets - These are usually made from either manganese steel or ni-hard type material. We can offer you advise on how to recover the screw heads, carrying jugs or to patch up worn areas. Mac Trode E6130 and Mac Nicro E215 can be used to patch up areas rather than replace the whole of the internal plates of the cabinet, therefore, making a very large cost saving.

噴丸室 - 通常由錳鋼或含鎳鑄鐵材料制成。我們可以為客戶提供如何恢復螺釘頭，搬運罐或修補磨損區域的建議。特種鋼焊條Mac Trode E6130和鎳合金焊條Mac Nicro E215可以用于修補區域，而不是替換整個機柜的內板，從而節省了非常大的成本。

4. Hard Face Applications - Hard Facing covers a very broad spectrum. Some applications require abrasion resistance while some application require impact resistance. Add to this the heat factor and it is easy to see how the “hardest” rod is often deposited and companies hope for a good result. We have an extensive range of hard face materials to cover all applications from tooling to agricultural repairs. We always ensure the correct electrode is used to maximise results such as Mac Hica E3071, Mac Hard E306 and Mac Hard E335T.

硬面應用 - 表面硬化覆蓋范圍非常廣。有些應用要求耐磨，而有些應用要求抗沖擊。再加上熱因素，很容易看出“最硬”的焊條經常是如何堆焊的，客戶希望有一個好的結果。我們有廣泛的硬面堆焊材料，涵蓋從工具到農業設備維修的所有應用。我們始終確保使用正確的焊條以得到非常有效的結果，如工模具鈷基焊條Mac Hica E3071(Stellite司太立1號)、耐磨堆焊焊條Mac Hard E306和Mac Hard E335T。

5. Pump Repairs - Is it Cast Iron? Is it Cast Steel? What is the workload? What abrasive factors are present? These are all questions we need to answer before we undertake any pump repairs. Often these questions are not considered and the result is the wrong electrode is chosen. The 3 most common products used in pump repairs are Mac Trode E66, Mac Cast E407 and Mac Stain E100ELC.

泵類修復 - 是鑄鐵的嗎？是鑄鋼的嗎？工作負荷是多少？存在哪些磨損因素？這些都是我們在修理泵類之前需要回答的問題。通常如果不考慮這些問題，結果就是選擇了錯誤的焊條。泵類維修中最常用的3種產品是鎳鉻合金特種鋼焊條Mac Trode E66、鑄鐵焊條Mac Cast E407和鎳鉻不銹鋼焊條Mac Stain E100 ELC。

6. Impellors & Worm Screws - The choice of repair method i.e. electric, gas or powder welding, will be governed by the type of equipment available and the skills of the maintenance team. Full training can be given to your team to enable them to became competent. The choice of weld material will be governed by the type of pulp etc. to be carried down the worm.

葉輪和蝸桿 - 電焊、氣焊或粉末焊修復方法的選擇，將取決于可用設備的類型和維護團隊的技能。我們可以對客戶的維護團隊進行全面培訓，使他們能夠勝任工作。焊接材料的選擇將取決于將被帶入蝸桿的漿狀物類型。

7. Shaft Repairs - Most companies will currently send shafts to an outside engineering company for repair. This usually proves time consuming and expensive. Shafts can easily be repaired  in house using either electric or powder welding with products such as Mac Trode E66 or Mac Powder P6. These repair methods can also  apply to keyways and bearing surfaces.

軸類修復 - 大多數公司目前都會將軸送至外部工程公司進行維修。這通常是費時和昂貴的。軸可以很容易地使用鎳鉻合金特種鋼焊條Mac Trode E66或粉末焊材Mac Powder P6在客戶公司內部修復。這些維修方法也適用于鍵槽和軸承表面。

8. Cast Iron Applications - It has become common practise for companies to shy away from cast iron welding. The reason many repairs fail is simply down to poor choice of electrode as well as incorrect welding techniques being applied.  Cracking is also  often the result of using too high or too low preheat temperatures, or the job being allowed to cool too quickly. We specialise in advising companies how to get the best results possible when welding cast iron by using the right product and the right technique.

鑄鐵應用 - 公司回避鑄鐵焊接已成為普遍做法。許多修復失敗的原因很簡單，是由于焊材選擇不當以及采用了不正確的焊接技術。開裂也往往是由于使用過高或過低的預熱溫度，或被允許冷卻過快。我們可以為客戶提供專業建議，如何在使用正確的產品和技術焊接鑄鐵時獲得非常滿意的效果。

9. Dissimilar Steel Applications - It is sometimes simple to select a standard dissimilar steel electrode, (AWS E312), for certain applications within your industry. However, on occasions it is possible to isolate areas of heat, impact, corrosion or abrasion to which we can apply one of our seven different dissimilar steel electrodes. Again the right electrode for the right application.

異種鋼應用 - 對于行業內的某些應用，有時很容易選擇標準的異種鋼焊條（AWS E312）。然而，在某些情況下，它可以隔離熱、沖擊、腐蝕或磨損區域，我們可以應用我們的七種不同的鋼焊材之一。再次強調要合理的應用合適的焊材。
