CONTENTS INTRODUCTION SECTION ONE WELDING
Underbead Cracking: The tendency for underbead cracking to occur is due largely to the presence of hydrogen in the weld metal. When steel is heated to approximately 720oC, the crystal structure changes to a form known as austenite, and in this state it is able to absorb appreciable quantities of hydrogen, such as may be introduced from the arc atmosphere.

Branch Connection Fittings (MSS SP
Branch Connection Fittings general Branch Connection fittings (also known as O'lets) are fittings which provide an outlet from a larger pipe to a smaller one (or one of the same size). The main pipe onto which the branch connection is welded is usually called the Run Get price

Defects Welding
Underbead Cracks, Toe Cracks: are a variation of cold cracks, which occur in the HAZ due to the presence of hydrogen and excessive hardness from rapid cooling of higher carbon and alloy steels. Hot Cracks: occur as the metal cools from liquid to solid and cannot withstand the solidification stresses. Get price

Visual Inspection of Welds
Visual examination is a method for identifying surface flaws and imperfections. Consequently, any conscientious quality control programme consisting essentially of visual inspection should include a continual sequence of examinations performed during all phases of fabrication. Get price

To prevent underbead cracking, only low hydrogen electrodes should be used when welding high yield strength, low alloy structural steels. (1) Correct electrodes. Hydrogen is the number one enemy of sound welds in alloy steels; therefore, use only low hydrogen ( MIL-E-18038 or MIL-E-22200/1 ) electrodes to prevent underbead cracking. Get price
