The Factors to be considered in Welding Repair - 0 views
-
Before a welding repair is carried out the need for repair must be carefully considered. If a component or structure contains defects of a known size, whether these are fabrication or service defects,
DYE PENETRANT INSPECTION - 0 views
-
A special dye is applied to the surface of the article to be tested. A suitable time interval allows it to soak into any surface defects. The surface is then freed from surplus dye and the dye in the crack revealed by either
GENERAL TECHNIQUES FOR TYPICAL REPAIRS - 0 views
-
The defect may be in a single run fillet weld requiring only a small amount of metal to be removed or it may be a large crack extending deep into parent metal.
Type of Defects which need to repair ! - 0 views
-
The repair of defects that occur during welding ranges from simple welding operations to improve weld profile to extensive metal removal and subsequent welding to rectify extensive cracking.
RADIOGRAPHY in Welding Inspection - 0 views
-
Gamma rays, similar to X-rays but of shorter wavelength, are emitted continuously from the isotope. It cannot be 'switched off' so when not in use, it is kept in a heavy storage container that absorbs radiation. They pass through the work to be inspected.
MAGNETIC PARTICLE INSPECTION - 0 views
-
The work is magnetized either by passing a current through it, or through a coil surrounding it. Defects on or near the surface disrupt the magnetic field (unless they are parallel to it)

TIG Welding Variables - 0 views
-
Welding Variables: Amperage : controls fusion and penetration. Voltage : controls arc length. Travel speed :controls depth of penetration. Gas flow rate :protects weld from atmosphere. Electrode extension :affects penetration.
TIG Weld Defects and Causes. - 0 views
-
Porosity cause by : Gas flow too low or too high. Leaking gas lines. Draughty conditions. Electrode stick out from nozzle too long. Contaminated/dirty weld prep. Contaminated/dirty wire. Incorrect gas shield. Arc length too long
General Cause Porosity, Overlap and Tungsten Inclusion - 0 views
-
Porosity. Is the result of gas being entrapped within the solidifying weld metal. Porosity will be present in a weld if the welding technique, materials used or condition of the weld joint promotes gas formation.
Surface Cracks in welding - 0 views
-
A crack is a linear discontinuity produced by fracture. Cracks may be longitudinal, transverse, edge, crater, centreline, fusion zone, underbead, weld metal or parent metal.
WELD DECAY IN AUSTENITIC STAINLESS STEELS - 0 views
-
Occurs in the HAZ due to the precipitation of chromium carbides. In the 5500C - 8500C range, the chromium leaches out of the grain and reacts with the carbon to form chromium carbides, due to the chromium having a greater affinity for carbon.
