Do your welds pass muster?

November 25, 2008

By:

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 approvals

May 13, 2008

By:

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.

Helium: In short supply

March 11, 2008

By:

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.

Keeping consumables from consuming welding profits

January 15, 2008

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.

Programmable lubricant application accelerates stamper's die changes

October 9, 2007

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.

New lube gives the slip to stamper's slips, trips, and falls

October 9, 2007

By:

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.

The tipping point

September 11, 2007

By:

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.

Choosing shielding gases for arc welding

September 11, 2007

By:

Proper selection of the shielding gas for gas metal arc welding (GMAW), flux-cored arc welding (FCAW), and gas tungsten arc welding (GTAW) processes can dramatically improve speed, quality, and deposition rate of a given weldment.

Dam the purge gas and full speed ahead

July 11, 2006

By:

Shielding gas is an often overlooked area of savings in tube and pipe welding. Creating a purge dam in one of several different ways can help you isolate the weld area and minimize the amount of gas and time needed to purge the weld zone properly.
