With its higher tensile and yield strengths, HSS is stronger at any given gauge than conventional "mild" steels. Initially, lighter-gauge HSS was used to replace heavier-gauge mild steel to reduce weight in many automotive parts, and this continues to be the most widely used application for HSS. However, as a new trend to run thicker and thicker gauges of HSS continues, stamping fabricators are evaluating their press feeding and coil handling equipment, as well as press tonnage capacities and die designs to ensure that these harder parts can be formed effectively. The dynamics of HSS have a bearing on feeding, straightening, and coil handling equipment.
Electron beam welding is useful for many applications -- steel, aluminum, and exotic metals; thick, structural sections or thin, delicate components; and harsh conditions such as alternating loads and low temperatures. A programmable controller allows engineers to tailor the electron beam's power distribution, thereby creating a unique weld for each application. EBW often is used in applications that have stringent joint tightness and strength requirements and, in some cases, it is used for welds that cannot be done with any other joining method.

In roll forming, non-stop punching and shear systems have traditionally employed simple open-loop control methods. Closed-loop (also called servo-based) systems can overcome many limitations of the open-loop design and yield higher line speeds, reduce downtime, and reduce scrap.

Laser beam sources with higher output powers and improved beam qualities have expanded the range of laser applications. Most system's lasers have power higher than 2 kW. Higher power does not always increase the speed, however. Increasing the power during thermal cutting value may cause increased heat-affected zones on the material and place higher demands on the motion system, thus limiting the cutting speed. A new patented cutting machine, the diffusion-cooled CO2 slab laser, may offer improved beam quality and smaller focus diameters under conditions comparable to conventional fast-axial-flow CO2 laser with 4-kW output power.

Planning an offline band sawing system can be complicated because it can affect, and is affected by, many interrelated factors. Breaking it down to infeed, sawing, and outfeed helps to frame the planning by breaking it down to three subprocesses. Furthermore, answering 15 pertinent questions can help you tailor an efficient sawing operation to your specific facility and sawing applications.

In recent studies, dry-film lubricants have been shown to give better lubrication conditions when compared to oil-based liquid lubricants. This factor, as well as savings in the amount of lubricant used, has helped increase the use of dry-film lubricants in the automotive industry for forming of aluminum and high-strength steel stamped parts
Given the range of advanced high-strength steels to be introduced into automotive bodies over the next decade, automakers must recognize the implication of non-traditional resistance spot weld failure modes.

Automotive parts manufacturer Pridgeon & Clay was looking for a way to manage the growth it was forecasting. The company decided to buy several robotic welding workcells and modular air filtration systems so it could rearrange the facility's layout and give the company the opportunity to buy one piece of equipment at a time.

Wiper dies are a fundamental requirement in modern tube bending applications in which tubes are bent at increasingly tight bend radii with increasingly thinner wall thicknesses. The design of the wiper die plays a key role in its performance and durability, as does its manufacturing method and the material from which it has been constructed.
