Electrodes for Cast Iron Fitting
Electrode used for welding cast iron is as follows:
Steel electrodes
Electrodes of this type when used for welding cast iron will Produce a strong weld deposit so it can not be machined. Thus Spake the electrode is used when the welding is not done anymore. To weld cast iron with steel electrodes can be used AC or DC welding plane poles reversed.
Nickel electrode
This type of electrode used for welding cast iron, when the welding is done again with the machine. Nickel electrode can be used in the sense of seeing the welding position. Ridge welding electrodes are produced in cast iron is flat and smooth when used in DC welding plane poles reversed. Characteristics of the nickel electrode can be seen in the table below.
Bronze electrodes
Welds by means of electrodes are resistant to cracking, so the length of the weld can be added. Core wire of the electrode is made of phosphor bronze and given a membrane That Produces a stable arc.
Electrodes for Aluminum.
Aluminum can be welded with electrodes made electricity from the same metal. The selection of aluminum electrode in accordance with the work table is based on information from the which the factory makes. Aluminum electrodes AWS-ASTM AI-43 for electric arc welding is a welding plane pole upside down where the use of DC currents expressed in the following table
Membrane Electrodes for Hard
Objectives in terms of hard coatings are conditions for use of equipment or materials are resistant to scraping That, punch and wear resistant. For this purpose the electrodes for hard coatings can be classified into three types are:
Scraping the electrode resistance.
Electrodes of this type are made of chrome carbide tube filled with carbide Filings. Electrodes with a diameter of 3:25 mm - 6.5 mm is used bicycles AC or DC welding plane poles reversed.
These electrodes can be used for hard coatings on the surface of a thin slice, expand the holes and some type of knife.
Electrode resistance blows.
These electrodes can be used on AC or DC welding plane poles reversed. Hard coatings used for the solver and a hammer.
Wear-resistant electrode.
These electrodes are made of non-ferrous alloys containing Cobalt, Wolfram and chrome. Usually used for hard surface coatings and the exhaust valve and valve seat wear in the which the temperature is very high.
