(Summary description)Selection method of welding materials:
1. Equal strength, the tensile strength of the deposited metal of the welding material is equal or similar to the tensile strength of the base material to be welded. This is the most commonly used principle for welding structural steel.
2. Equal toughness, the toughness of the deposited metal of the selected welding material is equal or similar to the toughness of the base metal to be welded. When high-strength steel is welded, the welding material with the strength grade rate lower than the base metal but equal toughness is often selected, that is, low combination, etc. toughness.
3. Equal composition. The chemical composition of the deposited metal is in line with or close to the base metal. This is the most important principle for material selection when welding stainless steel and heat-resistant steel.
