    Electrodes have identification numbers like E and sometimes color coding which are difficult to understand. Normally branded electrode from well known companies can be identified as there is a product guide on board. However often we discover electrodes packets in the store in unknown language and only the number is comprehendible. This article endeavors to help the marine engineers to recognize commonly used electrodes in engine room for Manual Metal Arc Welding. Generally there are general purpose electrodes in bulk and few kilograms of special electrodes like Low Hydrogen electrodes and Cast Iron electrodes etc. Recognizing a few electrodes and their applications can make life easier for the second engineer. The commonly use electrodes in engine room are as follows: E All position welding electrode that can be used with both AC and DC. It is useful for pipe welding. It produces a deep penetration weld and can weld over rust, dirt and paint also. It is also suitable for x-ray quality welding. It is a general purpose electrode for ship building. As it has fast freezing or rapid freezing of weld metal, it is also suitable for vertical and overhead welding. E It is a general purpose electrode which can be used with both AC and DC currents and produces a medium penetrating weld with a superior weld bead appearance. It is suitable for welding medium gauge steel and sheet metal jobs. It is also especially useful where there is poor fitting and wide gaps exist in the job piece.

    Cellulosic Electrode suitable for welding of root pass on every API 5L grade pipe, designed for vertical down.

    Main line welding Welding current: Pipeweld Type: Particularly suitable for welding on site, in downhill and overhead. Excellent radiographic qualities Welding current: Easy to use, smooth running and penetrating. OK Basic A reliable, general purpose, LMA electrode for mild and low-alloy steels.

    High welding speed in the vertical-up position. The electrode can be used for welding structures where difficult stress conditions cannot be avoided.

    YH5 LR: E52 3HH RS: Basic OK The root penetration is good, leaving a flat bead with easily removable slag. The stable arc and the well-balanced slag system make the electrode easy to weld in all positions.

    The electrode is designed for welding different structures including pipelines. An outstanding welding quality and very low-hydrogen weld metal minimises the risk of hydrogen induced cracking, with less or no preheating being required Welding current: EN DNV: EN GL: EN SS: EN UDT: Electrodes Packaging Vac Pac No rebaking The specially-designed packaging eliminates moisture pick-up.

    This results in very long storage time and dry, factory-fresh electrodes direct from the package without rebaking. The vacuum indicates no leakage which guarantees dry electrodes, thereby providing easy control and improved quality assurance.

    The date and time of issue can be recorded on the package. Small handy packages Depending on dimensions, the electrodes are available in packages of approximately 1, 2. Tin packing Hermetically-sealed metal packaging for cellulosic and basic electrodes ESAB is always close to its clients, committed to the acquisition of important orders also in countries where transport and storage of goods are difficult.

    For this reason ESAB developed and produced a tin package for welding electrodes. These hermetically sealed packages simplify and make transport and storage more safe, also ensuring the perfect preservation of cellulosic and basic electrodes, even in high-humidity and high thermal shock conditions.

    Wall thickness: Welding position: Welding direction: Preheat temp: Interpass temp: Can be combined with OK Flux Good slag removal also in tight bevels.

    Suggested for double jointing up to X In this study we calculated cancer risk due to exposure to these compounds in welders. Methods The role of exposure parameters in welders on derived incremental lifetime cancer risk were determined by stochastic modeling of cancer risk.

    Pipe Welding Procedures

    Input parameters were determined by field investigation in Iranian welders in and literature review. Conclusions Welders are at high and unacceptable risk of cancer. Control measures according to scenario analysis findings are advisable.

    In , about engaged in welding, soldering, cutting and brazing in the US 1.

    Welders are the specific group of workers because of their unique exposure pattern and occupational hazards that they are encountered with; including welding fumes.

    Inhalation exposure to welding fumes could lead to various undesirable effects ranged from simple pneumoconiosis to cancers 2. Occupational exposure to welding fumes is associated with coronary diseases, immu-notoxicological effects and respiratory effects 3 — 5. Lung cancer due to inhalation exposure to hexavalent chromium Cr VI and nickel Ni in welding fumes have been reported in several studies 6.
