The pipe joint design for manual welding is usually a V-bevel with a nil root face and root opening. Please read AddThis Privacy for more information. With a gap up to the sheet thickness between the sheet and the backing, there is some "flash" of weld metal into the gap, but full strength welds are still realized. Stringer beads and thin layers to minimize heat input are usually beneficial. Short circuit (GMAW-S) is a relatively low heat input process using 0.035- or 0.045-in. Common sources of the contaminating elements sulfur and phosphorus are marking crayons, paints, temperature indication markers, cutting fluids, oil and grease. It is a relatively low strength steel, but it may be quenched and tempered for increased strength. It has a nominal carbon content of 0.20% with approximately 0.50% manganese. In many applications it is also necessary to fillet weld the edges of the sheet to the steel backing. 98% of products ordered ship from stock and deliver same or next day. It has a good combination of strength and ductility and may be hardened and carburized. Commercial Quality. On a large firewater system for an offshore platform, orbital welding was able to reduce welding time to one half that of manual welding and cut reject rate from 15% to 5% (7) The joint design tolerances must be tightly controlled and are crucial for successful orbital welding. The liner was first fabricated by GTAW to close tolerances to fit into the carbon steel shell. The filler metal is ERCuNi, and the torch shielding gas is argon. Despite its unimpressive mechanical properties, the alloy is easily formed, machined, welded, and fabricated.
