After this heat-treatment process, the resulting hardness measured in the weld zone is very encouraging; the values comparable to the parent metal can be easily obtained.
Depending on the composition of the parent metal and the filler material used in the weld, the metal in the HAZ may be stronger or weaker than the parent metal.
However, due to extremely different properties, mainly the thermal expansion, a significant damage of brazing alloy and parent metal occurred--Fig.
Two grams of the air-dried sample was added to each test tube along with 10 mL of parent metal solution in 0.
The burr so produced on the edge is now harder than the parent metal, and will stand up to some cutting before it needs to be "steeled" again.
In one case, a raised or rough edge may be judged part of the parent metal and of no concern, and in another, it's an imperfection that must be removed.
Many welding procedures have been developed to address this disconnection in weld metal and parent metal composition and its effect on the end result.
In this case, hardening (increase of hardness) of the parent metal in the cross-section at a depth of 200 [micro]m from the surface along the circumference of the tooth, the walls and the depression was approximately the same.
So, at low spot power parent metal consists in solid solution with dendrite segregation, but the join is not possible to be made as is shown in figure 4a.
The first process is planishing the weld joint so the weld buildup is reduced to less than 10% of the parent metal thickness.
Applying the abrasive jet too close removed parent metal.
