interactions of dissimilar metals by a controlled detonation. By doing this the resultant composite system is joined with a durable‚ metallurgical bond. This explosive process is commonly utilized to clad carbon steel plate with a thinner layer of corrosion resistant materials such as stainless steel‚ nickel‚ alloy‚ titanium‚ and zirconium. Geometries that are usually produced are plates‚ tubing‚ and tube sheets‚ these are simple geometries because they are very limited during this process. During this

Define and explain the meaning of a predetermined manufacturing overhead rate that is applied in a job-order costing system? A predetermined overhead rate is the rate used to apply manufacturing overhead to work-in-process inventory. The predetermined overhead rate is calculated before the period begins. The first step is to estimate the amount of the activity base that will be required to support operations

Continuous improvement is a process of the seeking of small improvements in processes and products‚ with the objective of increasing quality and reducing waste. Continuous improvement is one of the tools that underpin the philosophies of total quality management and lean production. Through constant study and revision of processes‚ a better product can result at reduced cost. Kaizen (the translation of kai (“change”) zen (“good”) is “improvement” or “change for the better”) has become a foundation
