Quality as Part of the Contract

October 24, 2002

By:

Leaders who oversee weld designs, materials, methods, personnel training, and manufacturing teams should promote welding performance by addressing quality and testing issues in contracts for any work. Total quality systems and weld acceptance criteria must be specific--specified for each contract--and adherence must be enforced without wavering. Acceptance criteria for welding should be agreed to in a face-to-face meeting before fabrication begins. Before a project begins, all parties should agree on the retention time for inspection and test records—including X-rays, personnel qualifications and other project data--and the contract should state the location and description of the records storage facility.

One step forming simulation

Taking advantage of simulation technology

October 24, 2002

By:

One of the most valuable high-tech tools introduced in the last decade has been finite element analysis (FEA) simulation software that stamping tool makers can use to test forming conditions and design dies in the virtual world. This reduces tooling and product design time and saves costs of prototyping and experimentation to find the right design. Training the tool designer or process engineer how to use simulation software can provide a quick ROI and improve the bottom line.
