How to avoid surface concavity in autogeneous welding?
Do you mean your beads are concave and you would like them convex in appearance while autogenous welding is being done? Without knowing what metal you are welding or seeing the technique used I can only offer generalizations. It could be a lack of sufficient sulfur or improper travel speed. Without more info I'm only guessing.Which isn't good when it comes to welding.
What is Lack of fusion of weld fault?
It's when the different metals parts haven't melted together properly
Is welding a permanent bond?
used in aerospace and other high tech welds with lack of oxidation
What does the term lack of penetration mean in welding?
Incomplete penetration (IP) or lack of penetration (LOP)occurs when the weld metal fails to penetrate the joint. It is one of the most objectionable weld discontinuities. Lack of penetration allows a natural stress riser from which a crack may propagate. The appearance on a radiograph is a dark area with well-defined, straight edges that follows the land or root face down the center of the weldment.Mechanical Design EngineerMoustafa I.

Is there porosity on stainless welding?
Porosity is caused by molten puddle problems: oil, dirt, etc near weld, lack of shielding gas (tank is empty, or wind is blowing away gas. local vaccums for ventilation also can cause gas problems.) If mig welding, if you don't balance wire speed to amps, you may see porosity. Lastly, long arc'ing (too much distance from end of mig wire, to material) can cause bubbling.

How does behavior theory explain depression?
In the mid 1970s, Peter Lewinsohn argued that depression is caused by a combination of stressors in a person's environment and a lack of personal skills. More specifically, the environmental stressors cause a person to receive a low rate of positive reinforcement. Positive reinforcement occurs when people do something they find pleasurable and rewarding. According to learning theory, receiving positive reinforcement increases the chances that people will repeat the sorts of actions they have taken that led them to receive that reinforcement. In other words, people will tend to repeat those behaviors that get reinforced
