The slag is normally not quite as easy to remove as the slag from acid or rutileelectrodes, but, in spite of this, it can be classed as easily detachable.
When it comes to the tensilestrength of the deposit, Open the catalogue to page Description Classifications OK Multinational manufacturing, localrepresentation and an internationalnetwork of independent distributors brings the benefits of ESAB quality and unrivalled expertise in materials and processes within reach of all our customers, The risk of slag inclusions during normal production welding is therefore unusually small when basic electrodes are used, even if the slag is not completely removed between beads during multi-run welding.
Electrodes that have been redried. Stick electrodes Rutile and low-hydrogen electrodes are packed in cardboard packs with polyethylene shrink wrapping.
Precautions on site Keep the electrodes in electrically-heated quivers at a minimum temperature Labelling The electrode easb is clearly marked on the coating of each electrode near the grip end, e. Holding oven The holding oven is used for intermediate storage to avoid moisture pick-up in the coating of low-hydrogen electrodes and acid rutile stainless electrodes.

The water is divided into oxygen and hydrogen in the arc and the hydrogen in particular has a strong tendency to dissolve in the weld metal and initiate cold cracking. Welding current Maximum and minimum values are given. The most suitable welding current dependslargely on the size of the workpiece, the welding The weld metal from basic electrodes has a low hydrogen content and usually hasgood toughness even at low temperatures.
The evenness of the weld and the smooth transition of the base material make jointsproduced with rutile electrodes at least as good in terms of fatigue strength as unmachined joints produced using basic electrodes.
Electrodes that are considered to be in good condition and are transferred directlyfrom the store room after unpacking. Hydrogen forms from water in the surroundings and from the electrode coating.
Tensile properties Unless otherwise stated, tensile properties refer to all weld metal test pieces electordes according electrdes the rules of the classification societies using 4 and 6mm diameter electrodes. Electrodes that have been removed from their hermetically-sealed container. Dry basic electrodes when there is risk of cold cracking. The slag from basic electrodes has a lower melting point than that from rutile or acid electrodes. Storage Covered electrodes of any type will pick up moisture only very slowly if they are stored in the following climatic conditions: ESAB is one of few international companies to have achieved the new ISO standard in Environmental Management Systems across all our global manufacturing facilities.
VacPac is simple and convenient to use, ensuring that the electrodes keep their Care must be taken during storage and handling to prevent moisture being re-absorbed.
Stainless electrodes arepacked in polyethylene boxes with a re-sealablelid Figure electodes. Quality and environment standards Quality and the environment are two key areas of focus.
The electrodes which should be stored in the holding oven are: During certain periods in the summer and in The Online Industrial Exhibition. At ESAB, quality is an ongoingprocess that is at the heart of all our production processes and facilities worldwide. Basic electrodes are less Information about the different types of approval is available on request.
Official approval In addition to the official approval given in this catalogue, many OK electrodes are approved by foreign authorities, railway boards, private companies and so on. General information All covered electrodes are sensitive to moisture re-absorption to a greater or lesser degree.
