Otherwise, the weld could be prone to cracking as shown in Figure 11b. Backing has a recommended minimum thickness to prevent melt-through. For example, for SMAW it is 3/16 inches.See all results for this question

Production range of longitudinal welded pipe
Unlike double-sided submerged arc welding, the size, diameter and thickness of the steel pipe to be processed are much larger than those of high frequency welding. Therefore, double-sided submerged arc welded pipe (dsaw pipe) can be divided into butt welded pipe (also known as annular pipe) and straight welded pipe, and invisible welded pipe.Product-SIGNI WELDINGHenan signi Welding technology co., LTD was founded in 2000, is a domestic leading and wellknown enterprise in the welding and brazing market in China, who is engaged in the manufacture and distribution of welding consumables, located in Zhengzhou high & new technology industries development zone.Parametric Optimisation by Using Response Surface u shaped profile steel Submerged arc weldingParametric Optimisation by Using Response Surface Methodology (Rsm) of Submerged Arc Welding Process for Sa-516 Gr-70 Steel International Journal of Mechanical Engineering Research and Development (IJMERD) , Volume 3, Number 2 April - May (2013)

Longitudinal Submerged Arc Welding (LSAW) ~
Nov 20, 2020 · Longitudinal Submerged Arc Welding (LSAW) Longitudinal Submerged Arc Welding is the type of welding basically used for pipe which manufactured with weld. This is a specific welding technique used in pipe production. Production from longitudinal submerged arc welding is required high high wall thickness due to high internal and external pressure.Joint Efficiency Factors for A.O. Smith Line PipeThe weld metal was deposited in a wide U-shaped groove. Prior to welding, the pipe edges at the groove were pressed together so as to cause the lower part of the groove to deform toward the pipe interior into a recess in a backing bar to contain the weld root. The configuration of the welding arrangement is shown in Figure 1.Images of U Shaped Profile Steel Submerged Arc Welding See allSee all images
How big of a plate do I need to weld an arc filler?
It should note that the workpiece needs to be flipped on a large thick plate and welded on both sides of the weld concave rib plate, to prevent lifting when the weld cracking. The width of the control submerged arc filler weld should be <18mm to reduce defects. The weld width is the same.See all results for this questionHow To Weld Extra Thick Plates? | MachineMfgConsidering the existing conditions of the enterprise as well as the efficiency of various welding methods, it uses CO 2 gas to protect backing welding with submerged arc welding and cover surface.
