It is found that there is a structure at the same Fusion zone is ground into Austenite structure also has a δ-ferrite and skeletal Lathy δ-ferrite with another identical but with different grain size is found in each sample welding processes are different. By stainless steel AISI grades 304L through a connection with the GTAW process, found that large and coarse grain in as possible to be grades stainless steel AISI 304L that GMAW process through which the grain is smaller and less rough workpiece connected by the last GTAW stainless steel grade AISI 304L the EBW process through a small grain, and has the most detail.
