The weldability, repair quality and reliability of a furnace tube bear closed relation to the accumulated damage at microscale. Certain correlation between the hardness and damage could also be found.
With the rapid development of steel framed buildings, the steel plates for buildings must possess higher performances of strength, toughness, yield ratio and weldability, etc.
Aluminum-magnesium alloy has a poor weldability and often appears various defects, especially porosity, non-melting root zone, and so on.
Good impact and abrasion resistance. Excellent gas cutting property and weldability.
Especially attention shall be taken that the National Standards of Fasteners can not be used for high temperature operation, weldability and corrosion res...
「It is applied to product requiring high corrosion resistance, good weldability and medium strength, such as naval vessel, automobile,airplane,low-temperature equipment, television tower, drilling equipment, transportation equipment, missile component and armor.
Material for rail of crane is of strong strength because of high carbon content, but of poor weldability, which makes more cracks. Strict technique is required in such welding.
