ASTM A240 904L steel plate /sheet is a single phase austenitic structure, high Ni low C stainless steel, prone to hot cracking during welding, especially craters.
1. control of base metal and welding consumables in the S P and other harmful elements.
2. a large groove, small fusion than.
3. small heat input, not allowed to swing; 4, between the layers temperature ≤ 60 ℃.
5. a reasonable order of welding to reduce welding stress.
6. use low hydrogen welding consumables.
7. welding arc welding place after welding, to avoid crater cracks.
8. the back of the root cleaning, carbon arc gouging is not allowed to prevent carburizing.
