Hardness distribution on weld pass start and stop of propane/butane houshold pressure vessel

The problem of weakening due to non-stationarity on the beginning and the end of the weld is especially dangerous on pressure vessels. At materials with lower weldability like the fine grained high strength steel type it is possible to point out to this problem by simple measurement and comparison of hardness on the weld pass start and stop and on the point that has an enough distance from both (weld pass start and stop). In this paper the presence of differences between hardness on the weld start and the point that has a enough distance from the circular weld pass start and stop wished to be researched.
