Problems & Solutions

问题与解决方案

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.

作为一家制造商，我们不仅为客户提供正确的产品，而且确保在焊接之前、期间和之后使用正确的应用方法，我们为此感到自豪。请记住，如果你有幸拥有一辆法拉利，但放错了汽油，你可以肯定它不会发挥其正常性能。

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.

熔炉维修 - 熔炉工作温度通常高达1400°C，零件容易开裂。使用专门的Inconel铬镍铁合金焊条Mac Nicro E213、Hastalloy哈氏合金焊条Mac Nicro E215、以及不锈钢焊条Mac Stain E102等，这些零件可以很容易地进行维修，使它们能够更好地承受高温。

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.

喷丸室 - 大多数是锰钢或铁镍铸铁。使用正确的焊材，如我们的特种钢焊条Mac Trode E6130，并采用正确的维修工艺，可以很容易地为板、螺钉头和搬运夹具等应用节省大量成本。

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%.

砂回收场 - 砂具有极强的磨蚀性，导致无休止的磨损问题。使用三种不同类型的焊接工艺之一： (i)电弧焊、(ii)气焊、(iii)粉末焊。大多数磨损问题都可以解决，某些应用的寿命可提高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.

铁路和轨道工程 - 这些通常由锰钢制成，且大多易磨损。因此，使用类似成分的焊材，如我们的特种钢焊条Mac Trode E6130，它也工作硬化，将尽可能满足使用的要求。

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 - 持续振动会导致疲劳，最终造成零件开始破裂。普通焊材也无法承受这种振动。通过使用具有高抗拉强度和延申率的专用焊接工艺和焊材，可以克服这一问题，使零件能够在不担心开裂的情况下进行修复。

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.

轴类 - 通过使用电弧焊接或粉末焊接，这些普遍磨损的问题可以很容易地解决，大大节省成本，而没必要通过第三方外包公司。

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.

齿轮和链轮 - 轮齿经常因机器卡住而磨损或脱落。无论是铸钢还是铸铁，只要使用正确的预热和焊后热处理，就可以轻松地进行维修，减少停机时间。

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.

热处理托盘 - 随着温度的升高，这些托盘也会不断进行热循环。尽管焊接可以产生完全可接受的结果，但除非使用高镍合金，否则焊接失败是非常可能的结果。

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.

铸模修复 - 使用粉末焊接时，所涉及的热量很少，因此将大大的降低变形的可能。熔敷的深度可以精确到1毫米以下，减少了加工时间，最终缩短了修复铸模的时间。

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.

铸件修复 - 铸件通常含有铸造缺陷，可使用电弧焊或气焊轻松修复。通过使用正确的预热和焊后热处理，以及相同或类似合金的焊条，几乎完全消除了开裂的可能性。可加工性和颜色匹配也都很容易。
