Submerged Arc Welding SAW

Self-contained, mainly automated a.c. or d.c. systems with up to three welding heads. [Pg.199]

Copper-coated electrode wire can be solid or tubular. Tubular is used to supply the weld with additional alloying elements. Wire sizes range from 00.8 to 09.5 mm. [Pg.199]

Can use a strip electrode for surfacing to improve corrosion resistance (pressure vessels) or for hardfacing parts subject to wear (bulk materials handling chute). [Pg.199]

Large weld beads can cause cracking. Weld penetration can be controlled by using a backing strip when using high currents. [Pg.201]

Joint edge and surface preparation important. Contaminates must be removed from the weld area to avoid porosity and inclusions on each pass. [Pg.201]

Most nickel alloys can be fusion welded using gas-shielded processes such as TIG or MIG. Of the flux processes, MMA is frequently used, but the submerged arc welding (SAW) process is restricted to solid solution alloys (Nickel 200, Inconel alloy 600 series, and Monel alloy 400 series) and is less widely used. Solid solution alloys are normally welded in the annealed condition, and precipitation hardened alloys, in the solution treated condition. Preheating is not necessary imless there is a risk of porosity from moisture condensation. It is recommended that material containing residual stresses be solution treated before welding to relieve the stresses. ... [Pg.672]

The results of FeClj tests on submerged arc welds (SAW) showed that all top weld surfaces passed the test at 30°C (85 °F) without pitting attack, irrespective of arc energy in the range of 2 to 6kJ/mm (51 to 152kJ/inch). Surprisingly, the weld metal on the root side, which was the first to be deposited, did not pass the same test temperature. [Pg.453]
