Abstract:

On the basis of static shear and flexure fatigue tests, it is recommended that 97Ag-3Li braze all foil be used when repair TIG spot welding of 17-7PH stainless steel. This alloy can produce a spot welded-brazed joint which has 11 more static lap shear strength and 114 more flexure fatigue strength. TIG braze joints should not be used as they have less strength than normal TIG spot welded 17-7PH. The filler wire added to the weld nugget should be 17-7PH in preference to Type 308.
