Sheet Metal Fabricators - Sizzling Techniques For Welding Flat Rolled Metal

As fabricators acquire expertise welding SCS strip metal we discover wonderful information with reference to far better weld high quality, expense price savings on filler wire and, needless to say, decreases in harmful welding fumes as opposed to welding P&O steel. Still, we sometimes learn of a new user having problems with too much weld spatter while welding the SCS steel. Research show that modest alterations in shielding gas and filler wire feed eradicate excessive spatter and produce larger expense cost savings on consumables. This write-up offers the foundation of theSCS sheet steel strengths and describes welding practices that permit sheet metallic fabricators to enjoy those rewards while steering clear of the excessive spatter.

Consistently Stronger Welds. Six years ago comparable samples of welded SCS treated steel and Sizzling rolled pickled and oiled sheets were tested metals testing laboratory. It required an average 580 pounds greater shear load to induce failure in welded SCS treated steel samples than the P&O samples.

SCS treated metal benefit comes from greater weld integrity. A certain amount of weld arc's energy would go to burning up the oil on Warm band oiled sheets. This brings out even even more contaminants to a Pickled and oiled surface that is already fairly dirty when compared to SCS sheet steel. The net outcome is to lower the integrity of HRPO welds compared to SCS treated metal welds.

That Issue of Excess Spatter. Most sheet steel fabricators who switched to SCS treated metal reported cleaner, stronger welds with really no spatter. However, a handful noted unacceptable amounts of spatter.

To find out the underlying cause, The Material Works, Ltd. recruited the support of the Illinois Manufacturing Extension Center (IMEC) which provides technical services to companies. IMEC's project manager partnered with Optimum Engineering Solutions, Inc. to perform controlled welding tests of SCS sheet metal. They duplicated the welding procedures of fabricators who reported excessive spatter and observed similarly undesirable results.
