Sooner or later,your operation will have to be free of volatile organic compounds emissions. Using the latest lubricants can help. Lubricant suppliers have developed VOC-free lubricants that combine the best qualities of vanishing oils and water-extendible synthetic fluids, minus the mixing hassle associated with the latter.

With so many blends of shielding gas available, it can be a difficult task to determine which gas or gas blend best suits a particular GTAW application. To simplify that task, you must first understand the distinct properties that each gas or gas mixture brings to the table and how best to optimize the mixture once it's been determined.

For a job shop or manufacturer, maintaining weld quality begins with consistent shielding gas in the gas metal arc welding (GMAW) process. Consistently delivering the correct blend ensures proper arc characteristics and weld quality. Mixing technology, supply gas density, and gas usage patterns can affect the on-site gas blending system's ability to deliver a consistent blend.

Filler metal product approval codes can seem like a foreign language. One thing is certain, and that is each agency that establishes product approvals, such as AWS or ASME, does so to ensure filler metals meet the requirements for which they are intended. Understanding the meaning behind each set of filler metal product approvals will help you to better understand your filler metal's capabilities.

Shops that perform stainless steel, aluminum, or laser welding are feeling effects of the current helium shortage. Looking into gas blends with lower percentages of helium or alternative gases, and ensuring that day-to-day welding practices are not resulting in helium waste, will help these shops save money and helium supply.

Like every manufacturer these days, truck and trailer manufacturer Tico Manufacturing Inc. can't afford to waste any time on non-value-added activities. It recently switched its welders to Centerfire™ nonthreaded contact tips manufactured by Bernard®. These tips require replacement about once every two weeks; the previous tips were replaced three times a day. And because they are unthreaded, the tips take much less time to replace.

Red Rock Stamping, Chandler, AZ, airbag and seatbelt components manufacturer, looked for ways to improve its die change processes to handle the anticipated business volume increases. A lot of cleanup had been required around the machines as a result of the lubrication system. By installing a new fluid application system by UNIST, the stamper gained more control over the spray volumes and locations and reduced die change times. Fluid disposal was eliminated as well.

KI USA, a division of KI Japan, stamps and produces sub-assembly parts for Toyota, Honda, Nissan, and other "transplant" automotive OEMs. The stamper wanted to improve plant safety by reducing incidents of slips and falls. Petroleum-based stamping lubricants that had been used created a slippery environment at the press and other sites. Changing the stamping lubricant system to a synthetic lubricant from MS Fluid Technologies not only improved plant safety and appearance, it produced cost savings and reduced the plant's impact upon the environment.

Incorrect contact tip recess can cause excessive spatter, burn-through and warping, insufficient penetration, and porosity. Welders who become familiar with correct tip recess can avoid these problems as well as unnecessary equipment upgrades yet still improve GMAW quality.
