Titanium need not be all that hard to weld! In industrial sectors the common opinion is that titanium alloys are difficult to weld. While it is true that titanium alloys can be embrittled by carless welding techniques, it is equally true that these materials are much more weldable than their reputation suggests. This reference guide discusses the difficulties that originate from several basic sources when welding titanium and titanium alloys. The high reactivity of titanium with other materials, poor cleaning of parts before joining, and inadequate protection during welding can lead to contamination, porosity and embrittlement of the completed joints. Topics Covered: • Weld Cleaning • Gas Shield Arc Welding Processes • Gas Tungsten Arc Welding • Gas Metal Arc Welding • Plasma Arc Welding • Other Welding Processes
If you’re not ready for the depth of George Linnert’s "Welding Metallurgy", then this guide is for you. An intelligent introduction for the engineer new to welding, and the up-and-coming senior technician, this guide offers some basics that will aid the non-metallurgist in understanding why problems occur, and how to avoid them. Tables and figures support these topics: • Metal Structures • Metal Forms • Diffusion • Solid Solubility • Residual Stress • Shielding and Purging • Phase Transformation • Hardness and Hardenability • Grain Size • Stainless Steels • Aluminum and its Alloys • Copper and its Alloys • Refractory Alloys • Repair Welding
This hands-on manual provides a systematic method for identifying standard drills, standard taps, and various types of hand, machine and shell reamers used in industrial applications. Complete contents include: J2122 - Numbering System for Standard Drills; J2123 - Numbering System for Standard Taps; and J2124 - Numbering System for Reamers. A complete appendix section listing numerous examples of standard tool designations using the numbering scheme is also included. A valuable reference that will help OEMs and suppliers effectively communicate tool descriptions, as well as more efficiently catalog and supply tools!
It's no secret that lost races and crashes are caused by what is usually referred to as mechanical failure. But author Carroll Smith rightly contends that all failures are human in origin. Poor designs, incorrect manufacture and assembly, unreasonable demands, and negligent maintenance all lead to the dreaded "mechanical failure."
