Detailed Product Description

Material: Low-carbon steelSubmerged arc welding wire is used with corresponding flux and gotten excellent mechanicalseam,and has a series of advantages,such as high efficiency,stable welding quality,highdepositing efficiency,etc.This product is normally operated in the automatic or mechanized mode,however,semi-automatic (hand-held) submerged arc welding wire guns with pressurized or gravityflux feed delivery are available.The process is normally limited to the 1F,1G,or the 2F positions(although 2G position welds have been done with a special arrangement to support the flux).Deposition rates approaching 100 lb/h (45 kg/h) have been reported-this compares to~10 lb/h (5 kg/h) (max) for shielded metal arc welding.Currents ranging from 200 to 1500 A are commonly used;currents of up to 5000 Ahave been used (multiple arcs).Single or multiple (2 to 5) electrode wire variations of the processexist. SAW strip-cladding utilizes a flat strip electrode (e.g. 60 mm wide x 0.5 mm thick).DC or AC power can be utilized, and combinations of DC and AC are common on multipleelectrode systems. Constant Voltage welding power supplies are most commonly used,however Constant Current systems in combination with a voltage sensing wire-feeder are available.The series of welding wires are used to welding important low carbon steel and low alloy steelstructre, such as boilers, nuclear stations, chemical containers, bridge, ships, pressurecontainers etc.
