Metal Fabrication Videos I Made At Work


USING A SET OF HEM ROLLS: This video gives instruction on the proper use of the Mittler Bros. Hem Step Roll Set. This easy, three-step process creates hem rolls approximately 1/4″ deep on steel or aluminum up to .040″ thick without marring pre-painted aluminum. Rolls are available in HEAT-TREATED STEEL or COMBO STEEL & NYLATRON. PUNCHING JUST A HOLE WITH A SET OF PUNCH AND FLARES:   In this video you just drill a pilot hole for the draw bolt, then apply the tool and tighten the bolt for a smooth, flared or beaded hole in one easy step. Punch hole only … Continue reading Metal Fabrication Videos I Made At Work

Steel & Aluminum Characteristics


Aluminum  characteristics: The 3003-H14 has superior strength characteristics over pure aluminum and is easily welded with either TIG (tungsten-inert-gas) or oxygen-acetylene gas welders, yet remains malleable for shaping and bending. By comparison, a 6061-T6 aluminum alloy would yield even more strength than the 3003-H14, but the 6061-T6 is also more brittle and if welded, may develop stress cracks at the weld. Following is a list of aluminum alloys defined by a four-digit numeric code to identify the alloy content. The first digit represents the main element of the alloy. The alphanumeric code that follows the four digits (i.e “H14” or “T6”) is the … Continue reading Steel & Aluminum Characteristics
