Matters needing attention in selecting welding weathering steel plate

Posted:2020-02-01 15:10:29

The welding weathering steel plate has a good corrosion resistance effect, which has a good protective effect just now. When selecting the welding weathering steel plate, it is necessary to ensure its welding performance. Next, BBN will talk about what matters need attention when choosing welding weathering steel plate.

In addition to meeting the strength requirements, the welding weathering steel plate should match with the base metal in terms of corrosion resistance, because the total content of alloy elements in the welding weathering steel plate is less, its structure is a small amount of pearlite ferrite, with good plasticity and toughness, and the welding hardening tendency is small. The welding of weath ering steel plate generally adopts manual arc welding process. The deposited metal of the electrode should have corrosion resistance and comprehensive mechanical properties matching with the ba se metal, and the welding weathering steel plate should also have good process performance.

Carbon dioxide gas shielded welding: the welding process of welding weathering steel plate is similar to that of low carbon steel. First, clean up all kinds of dirt and rust on the surface of weldment and welding joint groove. For the structure with large plate thickness and restraint, preheating is required before welding, and for the steel with higher strength level, preheating is more necessary.
