A Brief Introduction To Laser Welding


Features and Applications
Austenitic stainless steel wire that has a low carbon content, which reduces the possibilities of intergranular carbide precipitation.
ER 308LSi is used to weld base metals of a similar chemical composition such as 304, 305 and 347 etc.
Increased silicon content promotes weld pool fluidity to give a smooth deposit appearance.
Ideal for applications requiring atmospheric corrosion resistance typically in urban and rural media’s.
Good mechanical strength at sub-zero temperatures down to -196°C.
Precision layer wound for superior wire feeding characteristics.
Typically used on a wide range of applications including pipe work, plate fabrication and vessel production etc.
