Abstract

Notice: All welding is carried out on the welder's own risk and account. Welding should be executed by a qualified and experienced welder and adequate safety measures should always be adhered to. The information and guidelines in this Welding Handbook are based on general information and knowledge at hand and are believed to be accurate and reliable, but the information and guidelines are not to be taken as a guarantee or warranty for a special purpose. The information and guidelines are provided to the welder solely for his own consideration, and Wilhelmsen Ships Service AS assumes no legal responsibility or liability for eventual damages and/or losses should the information and/or guidelines turn out to be incorrect or un-suitable. Wilhelmsen Ships Service AS is not liable for any loss or damages whatsoever and howsoever arising which is due to force majeure, other events beyond the reasonable control of Wilhelmsen Ships Service AS or events that could not reasonably be foreseen by Wilhelmsen Ships Service AS when this Welding Handbook was made. Wilhelmsen Ships Service AS is in no event liable for indirect, incidental or consequential damages or losses, including damages for loss of profits, resulting from lack of conformity, including but not limited to loss resulting from goods or software not working when connected to other goods/software or for any related cause thereto. Wilhelmsen Ships Service AS's liability shall in any event not exceed the total purchase price of theWilhelmsen Ships Service AS goods used during the welding operations. These conditions are automatically accepted by anybody using the information and guidelines in this Welding Handbook.

Wilhelmsen Ships Service AS enjoys close co-operation with its customers and would like to thank the many who have taken the effort to contribute with examples of successful solutions to real life maintenance situations. In 1943 the company name was changed to UNITOR. Mergers and increasing activity in the department for sales to ships led to the establishment of this department as a separate company; Unitor Ships Service AS in 1968.

Place the patch in the hole and secure it in position but do not tackweld it. As this will prevent the patch from expanding to heat. Now weld the patch to the casting, using the backstep technique as indicated in the sketch. Be careful to let each bead of 2 - 3cm cool off before proceeding with the next bead. Use Unitor NIFE-334N for the build-up.

The use of Yorcalbro piping allows a higher flow rate in the pipe than possible with copper piping. A flow rate up to 3.5m/s is permitted in Yorcalbro pipes compared to 1.52 m/s in copper pipes. Copper sea water piping on board ships has increasingly been replaced by Yorcalbro pipes. Yorcalbro (aluminium brass) is an alloy with the following chemical composition and mechanical specification: Some years ago, numerous welding tests were carried out on Yorcalbro pipes using the TIG (GTAW) process. The results were very satisfactory. Both small and large size pipes were welded in these tests, and the conclusions were as follows:

Caution: Storage temperatures higher than 45°C must be avoided since they accelerate the ageing process and destroy the product. Pickling chemicals give best result when they are fresh. Stir the gel to a smooth consistency. Spread a thick layer on to the work surface using the brush supplied. Allow the gel to remain for 50-90 minutes. Rinse off the reminding gel using fresh water. The waste water, after rinsing, contains acids and heavy metals, and must hence be treated according to local wastewater requirements before discharge. This can be done with neutralising agent or slaked lime. The waste water treatment should adjust the pH value of the clear water, pH 6,5-10, and precipi heavy metals into a sludge which should be sent for waste disposal. Recommended temperature limits for application: 10°C - 40°C. Application

Unitor FC-Wearbro 262 is specially suitable for building up damaged machine parts which have been subjected to impact, wear or bending strain, e.g. gear wheels, cams of all types, valve seats, bearing surfaces and shaft journals. Due to its low bonding temperature, high strength and toughness, it is also suitable for braze welding cast iron.

Cable drum for up to 100 m cable, order no. The conductor is built up from 0.2 mm diameter tinned copper strands to ensure flexibility. HO1N2-D means that the cable is produced to an international harmonized standard. Welding cables used on board, on deck or in an engine room, are exposed to both rough weather, oil and mechanical wear. The welding_. cable supplied by Unitor has wear, flame and oil-resistant insulation on a polychloroprene rubber basis. It is recognized by its marking at regular intervals with the text “Unitor oil resistant welding cable”, size of cable, and the standard for welding cable HO1N2-D. The cable drum with crank and floor stand is used for storage of up to 100 m cable. The crank may be disengaged to avoid accidents when unwinding cable. Cable drum It may also be ordered in other lengths, without connectors mounted.

Plasma, the fourth state of matter The process utilizes the electrically One common description of plasma is that it is the fourth state of matter. We normally think of the three states (At a temperature of between 2000°C (3600°F) and 10000°C (18000°F) a process of ionization and dissociation of the gas molecules take place. The molecules are split in molecular and atomic ions and free electrons. When this happens, the gas, which has now become plasma, is electrtrically conductive because free electrons are available to carry current).
