Abstract

The fatigue properties and S-N curves of the 3mm thickness SUS301L-MT and 5mm thickness SUS304 stainless steel sheet lap fillet welded joints made by plasma arc welding, plasma-MIG hybrid welding as well as resistance spot welding are investigated respectively based on the results of fatigue tests. The parameters of curves and the fatigue strength of the lap fillet welded joints are calculated. The influence of the 3 kinds of welding processes on fatigue resistance is discussed. Results show that compared with the fatigue tested results of resistance spot welded joint, the fatigue strength increases by about 73.7% and 39.5%, under the condition of 2ž106 cycle life, for plasma arc welding and plasma-MIG hybrid welding process respectively.
