OpERATION ARC MASTER 175 SE 4.12 Joint Preparations In many cases, it will be possible to weld steel sections without any special preparation. For heavier sections and for repair work on castings, etc., it will be necessary to cut or grind an angle between the pieces being joined to ensure proper penetration of the weld metal and to produce sound joints. -

Page 35: The Cause Of Distortion
OpERATION ARC MASTER 175 SE 4.20 The Cause of Distortion Art # A-07706 Distortion is cause by: A. Contraction of Weld Metal: Molten steel shrinks approximately 11% in volume on Figure 4-21: Parent metal contraction cooling to room temperature. This means that a cube of molten metal would contract approximately 2.2% 4.21 Overcoming Distortion Effects in each of its three dimensions. - Page 36 ARC MASTER 175 SE OpERATION E. Preheating Suitable preheating of parts of the structure other than the area to be welded can be sometimes used to reduce distortion. Figure 4-23 shows a simple application. By removing the heating source from b and c as soon as welding is completed, the sections b and c will contract at a similar rate, thus reducing distortion.
