Certain defects such as cracks are never tolerated but other defects may be acceptable within permissible limits. Overlap (Roll Over/Cold Roll) The protrusion of weld metal beyond the weld toe or weld root Travel speed too slow. Welding electrodes too large for the parameters or position Slag Inclusion A discontinuity consisting of slag entrapped in weld metal or at the weld interface Welds in joint too narrow a joint angle or initial joint gap. In 2015-03-04 2021-03-30 7.11.2 Weld repairs of wheel skids • Freight vehicles over 25 tonne axleload 22 mm • Passenger vehicles 25 mm • Locomotives 22 mm (See below) (For example, if the defect description falls between a class 2 and 3 thermal crack, then a class 3 thermal crack would be reported). A weld defect is defined as an imperfection or group of imperfections which is outside the limits stated in the appropriate application standard whereas weld imperfections are flaws present in the weld metal or in the adjacent parent metal. They may or may not cause rejection of the weldment. A weld discontinuity is an imperfection detected This type of weld defect occurs when there is an insufficient fusion between the base metal and the weld metal.

2020-05-31 · This type of defect occurs only on welding GTAW. Defects occur due to the melting of tungsten into the weld metal.

The poor overlap does not allow the slag from the previous weld to melt out and rise to the top of the new weld bead. It can also occur if the previous weld left an undercut or an uneven surface profile. 2019-02-12 · Such overkill is known as excessive weld penetration.

They may or may not cause rejection of the weldment. A weld discontinuity is an imperfection detected This type of welding defect occurs when there’s a lack of proper fusion between the base metal and the weld metal. It can also appear between adjoining weld beads. This creates a gap in the joint that is not filled with molten metal. Causes: Se hela listan på twi-global.com 1.

We can break down weld defects into the following main categories; Inclusions; Lack of fusion; Porosity; Undercut; Under-fill; Cracks; Excess reinforcement and excess penetration; Over-roll/Overlap When the weld face extends beyond the weld toe, then this defect occurs. In this condition the weld metal rolls and forms an angle less than 90 degrees. Causes of Overlap: 1. Improper welding technique.
