Problems & Solutions

問題與解決方案

As a manufacturer we pride ourselves in not only supplying the right product for the job but also in 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.

作為一家制造商，我們不僅為客戶提供正確的產(chǎn)品，而且確保在焊接之前、期間和之后使用正確的應(yīng)用方法，我們?yōu)榇烁械阶院馈Ｕ?qǐng)記住，如果你有幸擁有一輛法拉利，但放錯(cuò)了汽油，你可以肯定它不會(huì)發(fā)揮其正常性能。

1. Furnace Repairs - With working temperatures often as high as 1400°C parts are prone to cracking. Using specialised Inconel Hastalloy and stainless steel electrodes such as Mac Nicro E213/E215 and Mac Stain E102, these parts can easily be repaired leaving them better prepared to withstand such elevated temperatures.

熔爐維修 - 熔爐工作溫度通常高達(dá)1400°C，零件容易開裂。使用專門的Inconel鉻鎳鐵合金焊條Mac Nicro E213、Hastalloy哈氏合金焊條Mac Nicro E215、以及不銹鋼焊條Mac Stain E102等，這些零件可以很容易地進(jìn)行維修，使它們能夠更好地承受高溫。

2. Shot Peen Cabinets - Most are of a manganese steel or nihard type material. With the correct electrode, such as our Mac Trode E6130 and employing the correct repair procedures large cost savings to applications such as plates, screw heads and carrying jigs can easily be achieved.

噴丸室 - 大多數(shù)是錳鋼或鐵鎳鑄鐵。使用正確的焊材，如我們的特種鋼焊條Mac Trode E6130，并采用正確的維修工藝，可以很容易地為板、螺釘頭和搬運(yùn)夾具等應(yīng)用節(jié)省大量成本。

3. Sand Reclamation Plants - Sand is extremely abrasive causing endless wear problems. Using one of 3 different types of welding processes: (i)Arc welding, (ii)Gas welding, (iii)Powder welding. most wear problems can be combated, with certain applications experiencing an increase of life by as much as 300%.

砂回收?qǐng)?/span> - 砂具有極強(qiáng)的磨蝕性，導(dǎo)致無休止的磨損問題。使用三種不同類型的焊接工藝之一： (i)電弧焊、(ii)氣焊、(iii)粉末焊。大多數(shù)磨損問題都可以解決，某些應(yīng)用的壽命可提高300%。

4. Rail and Trackworks - These are usually made from manganese steel and are mostly subject to abrasion. Therefore using an electrode of similar composition such as our Mac Trode E6130, which also work hardens, will maximise the benefits possible.

鐵路和軌道工程 - 這些通常由錳鋼制成，且大多易磨損。因此，使用類似成分的焊材，如我們的特種鋼焊條Mac Trode E6130，它也工作硬化，將盡可能滿足使用的要求。

5. Shake-out Beds - The constant vibration of the beds causes fatigue and eventually parts begin to crack. Normal welding electrodes are also unable to withstand the vibration. By using specialised welding procedures and electrodes with high tensile strength and elongation this problem can be overcome, allowing the parts to be repaired without the fear of cracking.

落砂床 - 持續(xù)振動(dòng)會(huì)導(dǎo)致疲勞，最終造成零件開始破裂。普通焊材也無法承受這種振動(dòng)。通過使用具有高抗拉強(qiáng)度和延申率的專用焊接工藝和焊材，可以克服這一問題，使零件能夠在不擔(dān)心開裂的情況下進(jìn)行修復(fù)。

6. Shafts - By using either arc welding or powder welding these universal wear problems can easily be solved at large cost savings to your company rather than contracting out.

軸類 - 通過使用電弧焊接或粉末焊接，這些普遍磨損的問題可以很容易地解決，大大節(jié)省成本，而沒必要通過第三方外包公司。

7. Gears and Sprockets - Teeth are often worn or stripped through machine jams. Whether they are cast steel or cast iron, using the correct pre-heat and post heat treatment easy repairs can be made, minimising down-time.

齒輪和鏈輪 - 輪齒經(jīng)常因機(jī)器卡住而磨損或脫落。無論是鑄鋼還是鑄鐵，只要使用正確的預(yù)熱和焊后熱處理，就可以輕松地進(jìn)行維修，減少停機(jī)時(shí)間。

8. Heat Treatment Trays - As well as elevated temperatures these trays are also subject to constant thermal cycling. While welding can produce perfectly acceptable results, unless high nickel alloys are used weld failure is the likely outcome.

熱處理托盤 - 隨著溫度的升高，這些托盤也會(huì)不斷進(jìn)行熱循環(huán)。盡管焊接可以產(chǎn)生完全可接受的結(jié)果，但除非使用高鎳合金，否則焊接失敗是非?？赡艿慕Y(jié)果。

9. Pattern Repairs - When using powder welding there is very little heat involved, therefore minimising the possibility of distortion. Deposits can be accurate to less than 1mm in depth, reducing machining time and ultimately the time to repair the pattern.

鑄模修復(fù) - 使用粉末焊接時(shí)，所涉及的熱量很少，因此將大大的降低變形的可能。熔敷的深度可以精確到1毫米以下，減少了加工時(shí)間，最終縮短了修復(fù)鑄模的時(shí)間。

10. Casting Reclamation - Castings often contain foundry defects, which can be easily repaired using either arc welding or gas welding. By using the correct pre-heat and post heat, in conjunction with an electrode or wire of the same or similar alloy, the possibility of cracking is almost completely eliminated. Both machinability and colour matching are also overcome without any difficulty.

鑄件修復(fù) - 鑄件通常含有鑄造缺陷，可使用電弧焊或氣焊輕松修復(fù)。通過使用正確的預(yù)熱和焊后熱處理，以及相同或類似合金的焊條，幾乎完全消除了開裂的可能性?？杉庸ば院皖伾ヅ湟捕己苋菀?。
