303-SPL
Description
POSTALLOY® 303-SPL is a solid, gas-shielded wire designed for high strength welding of low carbon and low alloy steels. It utilizes a high degree of deoxidizers which purge the weld pool of impurities resulting in a weld deposit that is dense, porosity-free and "X-RAY" quality.

Recommended for single and multi-pass welding, and applications requiring deep penetration such as pipe or deep fillet welds. It is ideal for lightly rusted or thinly scaled surfaces and is especially good for applications that require machining after welding.
