The welding process and ambient temperature affect the structure and mechanical properties of welded joints in large-diameter (1,420 mm) pipes of manganese low-alloy steels, which are used commonly in oil and gas pipelines. Pulsed welding can improve the homogeneity of the structure and reduce the grain size of metal of the weld and HAZ zones. The ambient temperature causes structural changes, which affect the ductility and impact toughness in the welded joint zones. Temperature plays a role. Research shows that welding at 20 degrees C leads to an increase in ductility and impact toughness of 8 percent to 27 percent, and welding at -60 degrees C leads to an increase of 15 percent to 24 percent.

Owners of mid-sized businesses (those that sell for $2 million to $250 million) should know that the environment for selling such a business has grown increasingly harsh over the past 25 years or so. Many of the competitive forces at work in the global arena that have made manufacturing overseas attractive have made overseas manufacturing companies attractive investments, to the detriment of U.S. business owners. However, knowledge and planning can help an owner of a mid-sized manufacturing firm get a premium price for his business.

Choosing the right hydraulic press for your application is crucial. Identifying the right press capability up front can eliminate additional costs and startup delays. Four primary hydraulic press return capabilities are return on position, return on pressure, return on pressure with dwell capability, or combinations of the three. Shown is a press with return on pressure capabilities.
