As an additional offering for our customers, we can also perform rebuilds using Submerged Arc Welding or SAW for all types of parts. Submerged arc welding is a type of weld that allows the molten weld to be submerged under a type of material that is granular compound called flux. The flux becomes conducive and is the current path between the electrode and the part being worked on. This is a very safe way for parts to be welded as the flux covers the sparks and ultraviolet radiation and fumes that would normally be present without flux.
We have submerged arc welding capacities for parts up to 60” in width by 40’ in length and weighing up to 54,000 lbs. Materials typically used for submerged arc welding are Carbon steels, Low alloy steels, stainless, nickel-based alloys, copper, aluminum and even bronze.
Atlas' Certified welders use the submerged arc welding process to build up a hard stainless overlay on large rolls used in plastic manufacturing and paper industries. Parts can be rebuilt using this process by connecting two parts together with the weld and then our full service grind shop can grind the welded new part back to the customers' specifications.
There are several advantages using this process other than it is safer, such as it provides a very deep weld penetration, no edge preparation is necessary, distortion is much less and welds produced are sound, uniform, ductile, corrosion resistant.
