304 stainless steel laser welding

(PDF) Chemical and Mechanical Characterisation of AISI 304

Our previous work [15] concerning the AISI 304 laser welding allowed us to choose the range of parameters for the dissimilar welding tests.Taguchi method for design of experiments was used to determine which of the parameters have the most significant influence on Dissimilar GTAW between AISI 304 and AISI 4340 steel The joint of dissimilar metals between ferritic stainless steel (FSS) and low carbon steel (CS) are welded by laser beam with two different welding speeds:12. mm/s and 24. mm/s.

Weld solidification cracking in 304 to 304L stainless steel

Jan 01, 2010 · The Non-Destructive Laser Gas Sampling (NDLGS) process essentially involves three steps:(1) laser drilling through the top of a crimped tube made of 304L stainles steel (Hammar and Svennson Cr {sub eq}/Ni {sub eq} = 1.55, produced in 1985); (2) Laser Welding of Nickel ium and 304 Stainless Steel join NiTi and 304 stainless steel tubes 9.52 mm (0.375 in) in di-ameter through laser welding to create joints with weld depths up to 1650 µm (0.065 in). By joining NiTi to a common struc-tural material that is easily machined and readily welded to other materials,
