hot-cracking susceptibility increases rap­ idly for sulfur content above 0.010%. Therefore, even fully austenitic weld metals such as 25% Cr-20% Ni (Type 310S), can be improved substantially in hot-cracking resistance by lowering both phosphorus and sulfur contents to approximately 0.002%. It should be noted that both affect the hot-cracking

3C] during welding and wide the solidification temperature range. Three types of typical hot cracking (solidificati and on cracking, liquation cracking ductility dip cracking) occurred extensively in HMnS welds. The present studyprovides overall understanding of the hot cracking behavior in HMnS and discusses on its phenomena in

Hot cracking occurs due to the embrittlement of the weld metal or the partially melted zone (PMZ) during cooling between the liquidus and solidus temperatures or just below the solidus (Fig. 26).Hot cracks are characterized by their intergranular or interdendritic nature. Hot cracking is greatly influenced by the solute redistribution that takes place during solidification.

tribute to weld hot cracking in alloy 800. 2. To devise a model which explains the role of these elements in the crack formation process. Experimental Procedure Material The hot cracking susceptibility of four commercial heats of alloy 800 was evalu­ ated in this investigation. The composi­ tion of the four heats is listed in Ta­ ble 1.

Additionally, different welding velocities lead to changed solidification conditions with certain influence on hot cracking. This paper discusses the influence of energy per unit length during laser beam welding of AA 7075 on the change of element concentration in the weld seam and the resulting influence on hot cracking susceptibility.

In welding, the types of hot cracking that have been studied are weld solidification cracking, and weld heat affected zone liquation cracking [11]. Weld solidification cracking is analogous to hot tearing in castings, and refers to cracks associated with the presence of liquid films at solidification

Hot cracking is most often associated with liquid films that are present along grain boundaries in the fusion zone and the partially melted zone (PMZ) region of the heat‐affected zone (HAZ). Although widely used in the literature to describe a number of elevated temperature cracking phenomena, the use of the term "hot cracking" in this ...

Welds may fail due to over-load, under design, or fatigue. The cracking discussed here is the result of solidification, cooling, and the stresses that develop due to weld shrinkage. Weld cracking occurs close to the time of fabrication. Hot cracks are those that occur at elevated temperatures and are usually solidification related. Cold cracks ...
