Weld metal porosity is not a welcome sight in a weld bead, but it shows up all too often. Porosity is weld metal contamination in the form of a trapped gas. Shielding gases or gases released as a result of the torch being applied to treated metal are absorbed into the molten metal and released as in welds. 3.0 WELDABILITY OF STAINLESS STEELS Most stainless steels are considered to have good weldability and may be welded several welding processes including the arc welding processes, resistance welding, electron and laser beam welding, friction welding and brazing. For any of these processes, joint surfaces and any filler metal must be Accordingly, welding current can be as high as about 300A in horizontal fillet welding and 240A in vertical upward welding. Also, a wide range of arc voltage canbe used. Figure 3 shows bead appearances and cross-sectional macrostructures in horizontal fillet and vertical upward welding, respectively.

Developed the E O Paton Electric Welding Institute, Kiev, during the Second World War, SAW's most famous application was on the T34 tank. How to Weld - TIG Welding: TIG Welding is one type of welding amongst a few choices you have - MIG, Stick, Oxyacetylene, etc.TIG can be used to weld copper, titanium, even two dissimilar metals, and is handy for making tricky welds (e.g. S-curves, or welds on round things) Free to download book 29109-09 SMAW - Beads and Fillet Welds TG: 29109-09 PDF Nccer Download japanese ebook A Collection of Family Records, Chain intermittent fillet welds shall be opposite each other (fig. 3-30). D. Dimensions of staggered intermittent fillet welding must be shown on both sides of the reference line as shown in figure 3-31. Unless otherwise specified, staggered intermittent fillet welds on both sides shall be symmetrically spaced as in figure 3-32.

When it comes to welding, the process you choose is every bit as important as the tools themselves. Using the wrong welding process for a certain task can be like trying to saw a 2x4 with a screwdriver. Identifies and explains joint design and base metal preparation for all welding tasks. 29109-09 SMAW-Beads and Fillet Welds (1 class hours / 130 lab hours).

Shielded metal arc welding (SMAW) is the simplest, least expensive, and Metal arc welding is used widely in the fabrication of smaller fillet welds, because it is a although oxyacetylene welding is used on occasion. The slag created during this process must be chipped offthe weld bead after welding. The following table summarizes Please enroll in both A and B classes at the beginning of the semester. Topics will include: Welding Safety, Oxyfuel Cutting, Base Metal Preparation, Joint Fit-Up and Alignment, Welding Quality, SMAW Equipment and Set Up, SMAW-Electrodes, and SMAW-Beads and Fillet Welds Welding codes generally specify minimum values for the preheat temperature, The HAZ hardness control method, which is restricted to fillet welds, is based on the assumption that cracking will not occur if the hardness of the HAZ is kept below some critical value.
