15 widely used Welding may be carried out using both AC and DC currents with both polarities Basic coatings These are used essentially for high quality mechanical welding, although the arc tends to spatter and the appearance of the seam is less attractive than that of coated stick welding DC current is generally used with the electrode at the positive connection (reverse polarity), although there are some basic electrodes for AC currents The basic coatings are sensitive to humidity and therefore should be stored in a dry place inside sealed boxes You are reminded that steels with carbon content of over 06 must be welded with special electrodes Acid coatings These coatings provide high degree welding and can be used with AC or DC with a clamp-electrode on at the negative terminal (direct polarity) The molten pool is highly liquid and so the electrodes are basically suited to flat welding THE CHOICE OF ELECTRODE The choice of the diameter of the electrode depends on the thickness of the material, on the type of joint, and on the position of the weld When positive welds are made the pool tends to lower due to gravity, and therefore use of a small diameter electrode is recommended for repeated welds Large diameter electrodes need high welding currents which provide adequate thermal energy CHOICE OF WELDING CURRENT The stability and continuity of the weld mean that work can be carried out with low value currents in difficult conditions The following table shows the minimum and maximum current which can be used for carbon steel welding ELECTRODE DIAMETER WELDING CURRENT The stability and continuity of the weld mean that work can be carried out whith low value currents in difficult conditions The following table shows the minimum and the maximum current which can be used for carbon steel welding ELECTRODE DIAMETER WELDING CURRENT mm Minimum Maximum 1,6 25 A 50 A 2 40 A 70 A 2,5 60 A 110 A 3, A 140 A A 180 A A 200 A WELDING SCHEME WITH COATED ELECTRODE(Fig 2) 1 - Connect the earth cable to the negative terminal on the welding machine (-) 2 - Connect the electrode-carrier cable to the positive terminal (+) 3 - Insert the electrode into the electrode-carrier clamp 4 - Connect the machine to the electrical supply 5 - Place potentiometer n 2 in a suitable position in order to begin welding TIG WELDING PROCEDURE Gas Tungsten Arc Welding (GTAW) is the name of the welding procedure in which the arc is maintained during work through an infusible metallic electrode (usually tungsten)) The area of the arc (electrode and molten pool) is protected against atmospheric contamination through the use of an inert gas such as argon or helium which flows continually through the appropriate conducts in connection with the torch For purposes of simplification and uniformity all references to this procedure in this manual use the term TIG (Tungsten Inert Gas) SOLTER SOLDADURA SL INVERTER 5

16 This procedure may be used in clean and precise welds on all types of metal, respecting their physical-chemical composition Due to this characteristic, TIG welding is the only apt method for joining certain metals Due to these inherent characteristics in the TIG welding process the welding process to be carried out must satisfy certain exact specifications TIG welders are designed and constructed in accordance with these specifications Correct installation, use and maintenance will result in a long, satisfactory service, providing clean and proper welding The TIG torch is connected directly to the outlet of the welding machine and the manual gas control is induced in the torch Starting is facilitated by the characteristics of the generator The starting of the arc is often obtained through the use of a high frequency (HF) device which generates high voltage impulses (kv), however high frequency is not anticipated in scratch ignition but a momentary short-circuit situation; at the moment that the electrode is raised, the arc is produced and the current is transferred to the previously established value TIG WELDING SCHEME (Fig3) 1 - Respect the previously detailed indications on preparation and installation 2 - Connect the earth cable to the positive terminal + of the welding machine 3 - Connect the torch to the negative terminal of the welding machine 4 - Connect the argon gas cylinder to the device on the TIG torch 5 - Carry out welding, regulating the intensity using the potentiometer PROTECTION GAS FOR TIG WELDING The protection gas normally used is pure argon of variable quantity in accordance with the current used (4-8 l/min) The TIG welding procedure is suitable for welding steel (both carbon and alloys), and allows a welding with a top quality appearance, it is often used for a primary weld on tubes You must carry out detailed preparation and clean all edges before each weld CHOICE OF ELECTRODES FOR TIG WELDING The electrodes normally used are made of tungsten with Thorium (red colour) As a general guide we have provided a table with the diameters and the corresponding intensities Electrode (mm) Welding Current (A) 1, , PREPARATION OF ELECTRODES FOR TIG WELDING Special attention is needed in the preparation of the point of the electrode, as indicated in the following diagram The table below indicates recommended values for the angle of variation with the welding current Angle ( ) Welding Current (A) SOLTER SOLDADURA SL INVERTER 6
