Another main focus of sheet metal fabrication is welding. After the sheet metal parts are formed, they are assembled and tack welded into place. Various welding techniques can be used in sheet metal fabrication to avoid warping or other visual defects. These include using a stout fixture, welding in a staggered manner, covering the metal with sand during the cooling process, and special

The raw material for sheet metal manufacturing processes is the output of the rolling process. Typically, sheets of metal are sold as flat, rectangular sheets of standard size. Therefore the first step in any sheet metal process is to cut the correct shape and sized ‘blank’from larger sheet. 2 3 Sheet Metal Cutting & Forming Processes
the case ofmetal pipe a sheet metal blank is shaped by drawing through a forming die and the edges lapped or made to abut while the whole pipe is at a welding heat when the edges are welded together by pressure. Pipes are sometimes made seamless by drawing a thick tube through an annular die, but although the product by the latter process is a fine one, the cost of manufacture is great. T e
the formation of new oxide during the weld process. It is essential that proper preparations and precautions always be taken before welding commences. The surfaces to be joined and the area around the weld zone [~50 mm] must be degreased using a solvent [acetone or toluene] and a clean cloth. The area must be clean and completely dry as grease and moisture can form gases and cause pores in …

Because welding is a metal forming technique, it goes hand-in-hand with sheet metal fabrication, and each trade uses similar processes, like assembling and bending, to get the final product. To clarify, there are different ways to weld, including oxy acetylene, TIG (the most common form in fab shops), and gas metal arc (GMAW) welding.

inferior to base metal. These may be the failures caused as a result of welding but it is very important to analyze the failure modes, and effects of welding processes. Prior notification of these failures can prevent them by following control measures. This paper addresses the defect reduction in gas tungsten arc welding process using RCA and FMEA. Here, the prime objective is to evolve and
Keyhole welding of thin sheet metal is a very difficult process, but not having to move the keyhole is an advantage of conductive welding. Also because the conductive weld process tends to spread heat across the joint in a slightly wider pattern it also enables the development of a smooth weld bead.

In 20 to 22-gage sheet metal, your fit-up gap for MIG butt welding should be no less than the thickness of an unworn dime, but it doesn’t hurt to be stingy with your money and generous with your fit-up gap. I tend to use the thickness of an unworn nickel, or even a few thousandths more than that. – structural steel fabrication process pdf Sheet Metal • 10.1. Introduction current, and as a result, are most often used for automated welding processes such as gas metal arc welding, flux cored arc welding, and submerged arc welding. In these processes, arc length is kept constant, since any fluctuation in the distance between the wire and the base material is quickly rectified by a large change in current. For example, if the

Good sheet metal design should reduce, simplify, and mistakeproof shop floor processes to ensure greater efficiency and, ultimately, dramatic cost reductions. In other words, manufacturing should be as easy as possible. If, say, a new design eliminates welding but makes the bending process incredibly complex, the process is moving backward.
