What is a welding defect?
Welding defect is any type of defect in the welding task that threatens the use and function of the object that received welding. Defects of this type may occur for several reasons, including the use of incorrect materials during the process, or welders failure to fulfill the necessary tasks completely and efficiently. The welding defect can also be done due to the selection of incorrect welding techniques for a given role or for external conditions that prevent correct melting and curing of the weld.
cracks are one of the more common manifestations of welding defects. The nature of cracking can be caused by several different circumstances. For example, cracking of the arc stroke occurs when the location of the weld is affected by the welding rod, but the contact is not enough to create a sold weld. When the basic metal that receives weld, cold steel can be cracked and the amount of thermal input during process welding is not maintained to an acceptable extent. There may also be a wide range of other types of cracks, including the re -OhřeVU, subordinate and crater cracking. Each of these problems can be successfully solved in most situations, resulting in a strong weld that will have great stress.
Sometimes the welding defects will origin, with the welder to select the right technique or tools to perform the task. Different types of welding techniques are designed for use with different metals that call for certain welding rods and correct techniques to achieve ideal weld. When the welder cannot decide correctly in terms of the type of weld, rods and other equipment, the chances of defect of the welding will increase significantly.
The welding defect may also occur due to the failure of Perf.orm selected technique correctly. For example, persistent too long along the weld bead or too quickly moves along the line of beads, which could create an effect that weakens the result rather than to create a permanent seal between Weldishby anise sections. For this reason, the skill together with the choice of the right equipment and the best technique for specific work is important to avoid defects in the potential and require the work to be done for the second time.
