Again, weld strength is not determined by the level of penetration into the base plates. That is because a problem can arise if you have a lack of fusion in any part of the joint. See Figure 8 for an example of a centerline crack in a fillet weld. If penetration is too deep, centerline cracking a form of hot cracking may become an issue. Will using wet abrasive blasting instead of dry eliminate dust?
In other words, the purpose of arc welding is to achieve fusion between the initially separate pieces of metal.
