Clearing the Springback Hurdle
Among the challenges that face today's stamping professionals — competitive environment, increasing cost of materials, complex product designs, new materials, shorter project deadlines — springback is consistently listed among the hurdles or barriers to success. Springback, a longtime challenge to stampers, complicates nearly all of the challenges that face the business today and appears to be the "holy grail" of stamping technology. Addressing springback is a multifaceted and complex challenge. The use of computer-aided engineering has made achieving safe panels a seemingly elementary exercise, however, dimensional accuracy is still somewhat elusive. Springback is not a new phenomena introduced only by the use of high-strength and exotic materials, but instead is a certainty for all stamped metals — a certainty that once properly understood can be addressed with great success.
The Study of Effect for Bending Operation Having Working Hardening on Hydroforming Parts
This study is concerned with working hardening of bending operation on hydroforming parts. Generally, hydroforming parts having the complicated shape of the automobile require a three-dimensional bending operation. This operation involves several variations in the tube, which are the thickness, the mechanical characteristics, the hardness, the circumference and so on, on original tube. The variations and the affect on the hydroforming operation and hydroforming parts are studied. The authors used two methods, one of which was computer simulation and the other the actual test in the plant. The results of two experiments with several tables and graphs were analyzed.
Phased Array Ultrasonic Inspection of Pipe Welds
Welds have been inspected by radiography for years, but this technology has major drawbacks: low detection rates for critical planar defects (i.e., cracks and lack of fusion), subjective interpretation, no vertical sizing capability, significant safety hazards, licensing issues, chemical wastes, plant closures and is generally slow. For decades, the main alternative was manual ultrasonics, which is also slow, subjective and normally has little hard-copy record.

New Classes of AHS and UHS Steels
New grades of steel, dual phase and TRIP were developed offering superior combinations of strength and ductility, when compared to traditional higher-strength grades. These steels, available up to 980 MPa minimum tensile strength, typically exhibit high ductility, excellent work and bake hardening characteristics, and high n-value. Dual-phase and TRIP steels can be considered to replace, at lighter gauge, all HSLA grades for a lower-mass, high-performance application. These grades can be considered for energy absorption, intrusion minimization and all parts requiring a good combination of high strength and ductility.
Aqueous Cleaning of Tubes Basic Technique and Applications
In most industrial manufacturing, metal cleaning is an operation that can contribute to improvements in quality and thereby lead to competitive advantages. Some market segments specify cleanliness standards. The tube manufacturing and tube fabricating industry is no exception; tube washing has become an important part of the production process. In the past few years, demands for change in production processes have taken place. Regulations are specifying more environmentally friendly products.

Application of Dual-Phase and Other High-Strength Steels for Hydroform Applications
Dual-phase and other advanced high-strength steels can be used to develop cost-effective lightweight hydroforming components. Knowledge of the full process chain from slab to the performance of the actual hydroforming product is vital to the successful use of advanced high-strength steels in hydroforming components. The material choice significantly influences the component and production process design, while the process control throughout the supply chain from slab to tube making strongly influences the success of the hydroforming process.
Improving Roll Forming Operations Through Effective Shop Floor Control
Metal fabrication manufacturers need to consider the latest computer technology as a means of improving both the quality of products and efficiency of operations. An easy way to improve the quality of goods produced is to minimize the number of data entry points. This use of computer technology will reduce human errors, and can verify the material used against the material specified as well as provide a link between the production line and an ERP system.
