- Page 14 Arc Welding Techniques Corner Weld - A Word for Beginners (Fig 1-19g) 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 Tee Joints be carried out in the down hand position. Make sure (Fig 1-19h)
- Page 15 If the travel is too fast, the bead will be narrow and strung out and may even be broken up into individ- ual globules. If the travel is too slow, the weld metal piles up and the bead will be too large. www.weldtech.net.nz...

It is important to do this to prevent slag being trapped by the sec- ond run. Subsequent runs are then deposited using either a weave technique or single beads laid down in the sequence shown in Figure 1-22. The width of...
