    Traditionally, welding thin materials whilst avoiding “blow-through” can be tricky with the MMA process. This being said, however, welding thin materials with a Strata machine will be noticeably easier because the arc is so stable and the output can be very finely adjusted down to very low amps.
  • Page 10 EZIMIG185C 4.2.2 The MIG Process 4.2.2.1 Description The acronym MIG stands for Metal Inert Gas. Metal’ refers to the fact that the filler metal itself (the MIG wire) is used to conduct the welding current to the job and create the arc. Inert Gas refers to the fact that the process relies on an inert gas to prevent weld oxidisa on.

    EZIMIG185C 4.3 Joint Preparations In many cases, it will be possible to weld steel sec ons without any special prepara on. For heavier sec ons and for repair work on cas ngs, etc., it will be necessary to cut or grind an angle between the pieces being joined to ensure proper penetra on of the weld metal and to produce sound joints.

MIG BASIC WELDING GUIDE 5.1 MIG Basic Welding Techniques Two different welding processes are covered in this sec on (GMAW and FCAW), with the inten on of providing the very basic concepts in MIG welding, where a welding torch is hand held, and the electrode (welding wire) is fed into a weld pool, and the arc is shielded by a gas (GMAW) or flux cored wire (FCAW).

  • Page 14: Position Of Mig Torch

    EZIMIG185C 5.4 Position of MIG Torch The angle of MIG torch to the weld has an effect on the width of the weld. The welding torch should be held at an angle to the weld joint. (See Secondary Adjustable Variables below). Hold the torch so that the welding seam is viewed at all mes.

  • Page 15: Mig Welding (Gmaw) Variables

    EZIMIG185C 5.7 MIG Welding (GMAW) Variables Most of the welding done by all processes is on carbon steel. The items below describe the welding variables in short-arc welding of 0.6mm to 6mm mild sheet or plate. The applied techniques and end results in the MIG process are controlled by these variables.
  • Page 16 EZIMIG185C 3. Nozzle Angle: This refers to the posi on of the welding torch in rela on to the joint. The transverse angle is usually one half the included angle between plates forming the joint. The longitudinal angle is the angle between the centre line of the welding torch and a line perpendicular to the axis of the weld.

    EZIMIG185C 5.8 Establishing the Arc and Making Weld Beads Before a emp ng to weld on a finished piece of work, it is recommended that prac ce welds be made on a sample metal of the same material as that of the finished piece. The easiest welding procedure for the beginner to experiment with MIG welding is the flat posi on.

    EZIMIG185C 5.9.4 How to determine correct Wire Speed/Voltage Setting If the Current/Amperage (Wire Speed) is too high for the welding voltage, “stubbing” will occur as the wire dips into the molten pool and does not melt. Welding in these condi ons normally produces a poor weld due to lack of fusion.

    EZIMIG185C 5.13 MIG Welding Troubleshooting The general approach to fix MIG welding problems is to start at the wire spool then work through to the MIG torch. There are two main areas where problems occur with MIG: Porosity and Inconsistent wire feed.

STICK (MMA) BASIC WELDING GUIDE 6.1 Size of Electrodes The electrode size is determined by the thickness of metals being joined and can also be governed by the type of welding machine available. Small welding machines will only provide current (amperage) to run smaller sized electrodes.

  • Page 25: Types Of Electrodes

    EZIMIG185C 6.5 Types of Electrodes Arc Welding electrodes are classified into a number of groups depending on their applica ons. There are a great number of electrodes used for specialised industrial purposes which are not of par cular interest for everyday general work.

    EZIMIG185C 6.7 MMA Welding Techniques 6.7.1 A Word for Beginners For those who have not yet done any welding, the simplest way to commence is to run beads on a piece of scrap plate. Use mild steel plate about 6.0mm thick and a 3.2mm electrode.
  • Page 27 EZIMIG185C 6.7.4 Arc Length As soon as the arc is established, maintain a 1.6mm to 3.2mm gap between the burning electrode end and the parent metal. Draw the electrode slowly along as it melts down. The securing of an arc length necessary to produce a neat weld soon becomes almost automa c.

Refer Figure 56 and Figure 57. A piece of angle iron is a suitable specimen with which to begin, or two lengths of strip steel may be tacked together at right angles.

Use a 3.2mm of the job and strike the arc in the corner of the fillet. The electrode needs to be about 10º from the horizontal to enable a good bead to be deposited.
  • Page 31 EZIMIG185C 6.8.4 Overhead Welds Apart from the rather awkward posi on necessary, overhead welding is not much more difficult that down hand welding. Set up a specimen for overhead welding by first tacking a length of angle iron at right angles to another piece of waste pipe. Then tack this to the work bench or hold in a vice so that the specimen is posi oned in the overhead posi on as shown in the sketch.
