Autotherme-307 is a solid wire for GMAW process, available in bright finish, gives
smooth flow, stable arc and spatter free under optimum welding conditions. It gives
radiographic quality weld deposit. The weld metals highly crack resistant and its
unique mechanical properties are maintained even when welding steels of different
compositions. It is ideally suited for welding HSLA steels like armour steels etc. in cast
or rolled forms. It is also useful for fabrication of hull & turret of T-90 tank, austenitic
manganese steel and for producing stainless steel overlay for corrosion resistance,
buffer layers for hardfacing and work hardenable deposits. These spools are best
suitable for automation through robotic welding system.
