Part I The arc strike is similar to a very small weld, one made without preheat and certainly smaller than the minimum weld size required to reduce the risk of cracking. The arc strike cools very rapidly, leaving a very small but very hard surface and heat-affected zone (HAZ). A high-hardness HAZ increases the risk of brittle fracture, hence an arc strike may serve as a crack initiator.
