Welding Construction Term

A short stick of welding filler metal consisting of a core of bare electrode covered by chemical or metallic materials that provide shielding of the welding arc against the surrounding air. Welding may be accomplished by arc resistance friction or other suitable process with or without external gas shielding.

The molten weld pool is shielded by this slag which moves along the full cross-section of the joint as welding progresses.

Welding construction term. Year-2007 Egypt Welding Terminology Definitions What is a Weld. A localised coalescence of metals or non-metals produced either by heating the materials to the welding temperature with or without the application of pressure or by the application of pressure alone AWS A permanent union between materials caused by heat and or. Bond the joining of welding metal and base metal.

Weld Pass - Made when you deposit the filler metal on the plate or joint while traveling the length of the PARENT METAL. With a 6 mm leg length toes to be blended smoothly. Backup Strip is a strip or section of steel butted up to an open gap between two pieces of steel.

In the construction industry though workers predominantly use steel and MIG welding is also widely employed for steel work. Abrasion Resistant Overlay tough outer layer that is resistant to impact gouge abrasion and penetration commonly used for bores Back End Crews behind welding crew comprised of pipe gang and firing line Bead 1st. All three of these processes use the same method of forming an electric arc between an electrode and the metal.

Arc Voltage the voltage that runs along the welding arc. Three intermittent fillet welds with 6 mm leg lengths the length of each weld 25 mm and the distance between each weld 40 mm. A groove-weld symbol may be added to a welding symbol below the reference line to specify a weld only on the arrow side of the joint single weld.

Also known as SMAW or Stick Metal Arc Welding. It is used to prepare joints for connection in the shop and on site and for the attachment of other fixtures. With over 50 of the steel produced globally used in construction of commercial and residential buildings theres an enormous demand for welding on site.

37 Submerged-arc welding SAW - an arc welding process which produces. - A welding process producing coalescence of metals with molten slag which melts the filler metal and the surfaces of the work to be welded. 6010 welding rods can be used for open butt welding but 7018 cannot and requires a backing strip to provide a surface for the electrode to weld.

1- Most welding operations are performed manually and are expensive in terms of labor cost. It also completes the electrical circuit thereby creating the arc. A continuous fillet weld.

Or weld symbols may be added both below and above the reference line to specify a double. 2- Most welding processes are inherently dangerous because they involve the. Welding Inspector Terms Definitions Section 2.
