Welding properties of steel refers - under given conditions of welding, steel construction, good performance of welded joints. Welding performance can be divided into two welding performance welding process welding properties and performance. Welding process welding performance refers to the welding process welds and weld metal is not close to thermal cracking or cooling does not produce cooling shrinkage cracking sensitivity. Since the steel at high temperatures and long loads, steel, and its breaking strength than the short-term strength decreases more, so long steel under high temperature, long term strength to be determined. Steel will automatically harden over time, become brittle, or "aging" phenomenon. Steel under low temperature loads to test its toughness.
