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. The marine industry is somewhat unique insofar as many of the repairs such as cast iron seem very general, but occasionally the requirement of “special” alloys is of paramount importance. This is where MWA International Ltd comes into its own with our extensive range of electrodes.
作為一家制造商，我們不僅為提供正確的焊接產品，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。船舶工業是有點獨特的，因為許多維修，如鑄鐵似乎非常普遍，但偶爾“特殊”合金的要求也是至關重要的。這就是MWA公司憑借自有廣泛的焊材系列而獨樹一幟的地方。
1. Cast Iron Repairs - Many components on ships may be made from cast iron such as pumps, valves, engine blocks, winches etc and all will very likely be contaminated with oil/grease or salt water. The MWA range of cast iron electrodes have been designed to overcome these problems and deposit a sound, porosity free weld with maximum ease of application. Mac Cast E405 and Mac Cast E407 are particularly useful in joining cast iron to mild steel.
鑄鐵件維修 - 船舶上的許多部件都由鑄鐵制成，如泵、閥門、發動機缸體、絞盤等，所有這些部件都很可能受到油脂或鹽海水的污染。MWA系列鑄鐵焊材的設計旨在克服這些問題，并在上易于應用的情況下，形成一個良好的、無氣孔的焊縫。鑄鐵焊條Mac Cast E405和 E407在連接鑄鐵和低碳鋼時特別有用。
2. Bronze Repairs - Most naval bronzes tend to be of a higher % tin than standard bronzes, this helps give better anti sea water corrosion properties. The electrode recommended would be Mac Bronze E809 (DC output required). This electrode has many uses including bushes, bearings and propellor components.
青銅類修復 - 大多數船用青銅的錫含量往往高于標準青銅，這有助于提供更好的抗海水腐蝕性能。推薦的焊條為銅合金焊條Mac Bronze E809(直流)。這種焊條有許多用途，包括襯套、軸承和螺旋槳等部件。
3. Shaft Repair - The most effective electrode for shaft repair is Mac Trode E66, this electrode will give a deposit resistant to heat, abrasion, friction and corrosion. As with all shaft repairs the correct deposition method should be used to prevent problems such as distortion.
軸類修理 - 用于軸類維修的最有效焊條是鎳鉻合金特種鋼焊條Mac Trode E66，該焊條將提供耐熱、耐磨、耐摩擦和耐腐蝕的熔敷物。與所有軸類維修一樣，應使用正確的堆焊方法來防止變形等問題。
4. Armour Plate - On occasions it is required to join armour plate to other materials, two electrodes can be used Mac Trode E66 or Mac Stain E101Mo.
裝甲鋼板 - 在需要將裝甲鋼板與其他材料連接的情況下，可以使用以下兩種焊條，即鎳鉻合金特種鋼焊條Mac Trode E66或不銹鋼焊條Mac Stain E101 Mo。
5. Stud Removal - A very costly application is the removal of broken bolts or studs. Whilst the drilling and re-tapping is inexpensive but time is not !! With this in mind MWA has developed Mac Stud E73 which will remove broken bolts and studs without damaging the threads. A job which would normally take hours now just takes minutes.
螺柱拆除 - 拆除斷裂的螺栓或螺柱是一種成本非常高的工作。雖然鉆孔和重新攻絲本身成本低廉，但需要浪費不少寶貴的時間。考慮到這一點，MWA公司開發了專門用于螺栓拆除的焊條Mac Stud E73，它可以在不損壞螺紋的情況下移除斷裂的螺栓和螺柱。通常需要幾個小時的工作現在只需要幾分鐘就能輕松完成。
6. Valves seats/heads - Repairs to either valve seats or heads need to be tough without being too hard, they also need to be corrosion resistant and sometimes heat resistant, the electrode recommended is Mac Hica E3072.
閥門 - 閥座或閥頭堅韌而不太堅硬，耐腐蝕且耐熱。推薦使用鈷基焊條Mac Hica E3072(Stellite司太立6號)。
7. Submarine Plate/Duplex Alloys/Martensitic Alloys - As stated previously, many naval requirements will request special electrodes, a repair may be required where a material match is vitally important e.g. Submarine plate: electrode Mac Trode E61108-M is the chosen alloy. Duplex alloys 2205 or 2207 would require electrode Mac Stain E122/E125.
海底鋼板/雙相合金/馬氏體合金 - 如前所述，許多船用需求要求特殊焊材。在材料匹配極其重要的地方可能需要修復，如海底鋼板：所選焊條為E61108-M。雙相合金2205或2207需要使用不銹鋼焊條Mac Stain E122或E125。
8. Cladding Valves/Pumps (625) - On occasion’s internal bores on pumps and valves are repaired to increase service life in excessively corrosive condition, Mac Nicro E213 is the answer, depositing a “Inconel 625” type weld metal.
包覆閥/泵（625） - 泵和閥門上的內孔有時需要修理，以增加在過度腐蝕條件下的使用壽命，鎳合金焊條Mac Nicro E213就是理想的選擇，它熔敷了Inconel 625合金焊縫金屬。
For any of the above applications please feel to contact MWA or local partner for any technical advice, the Marine Industry is moving forward very quickly and materials and methods are constantly changing.
