  • Page 57 TRANSMIG 350i, 450i, 550i Arc Welding Technique - A Word to 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. Clean any paint, loose scale or grease off the plate and set it firmly on the work bench so that welding can be carried out in the downhand position.
  • Page 58 TRANSMIG 350i, 450i, 550i If the travel is too fast, the bead will be narrow and strung out and may even be broken up into individual globules. If the travel is too slow, the weld metal piles up and the bead will be too large.
  • Page 59 TRANSMIG 350i, 450i, 550i B. Fillet Welds These are welds of approximately triangular cross-section made by depositing metal in the corner of two faces meeting at right angles. Refer to Figure 4-14. 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.
