The welding process optimal welding technology of high strength Hole drillingFriction Bit Joining of Similar Alloy Sheets of High optimal welding technology of high strength Hole drillingDrilling was found to be an important factor in peak weld strength. Number of flutes on the consumable steel bit was varied to see the impact of better and worse chip clearance ability. Increasing number of flutes was found to positively impact peak weld strength to a point. Optimal number of flutes was found to be different for each type of testing.Author: Matthew R OkazakiPublish Year: 2018
Hole Drilling - an overview | ScienceDirect Topics
Hole drilling is effective for through-thickness cracks in plates, or plate components of structural members. 5.8.2 Weld toe grinding. Weld-toe grinding reduces the geometrical stress concentration and extends the fatigue life of undamaged details. Grinding can be used to remove shallow fatigue cracks that may exist in the weld toe.Hole-Drilling Strain-Gauge Method: Residual Stress optimal welding technology of high strength Hole drillingNov 02, 2009 · Nov 02, 2009 · When measuring residual stresses using the hole-drilling strain-gauge method, plasticity effects arise if the residual stress level exceeds about 60% of the material yield strength. In this case the classical methods, which are based on the linear elastic material behavior, do not work properly and residual stresses are overestimated.Horrendous Holes | Cutting Tools | Machining TechnologyMay 29, 2014 · May 29, 2014 · Cutting Tools Click image to enlarge by Kip Hanson. Cutting super alloys can be a formidable machining challenge. Nickel and cobalt-based superalloys may not be Kryptonite, but drilling holes in Hastelloy X, Inconel 625, Waspaloy and Haynes 25 is about as tough as it gets in the world of metal removal.
