Abstract: The new welding process avoids cracking in welding, in repair welding or in cladding of parts of metallic alloys which are sensitive to hot cracking. The process is using a first heat source (15), directed to the parts (11, 12) of the metallic alloy forming a melt pool (14) on the parts (11, 12) of metal or metallic alloy. The heat source (15) and the parts (11, 12) are moved relative to each other. The process is characterized in that there is one (13) or more additional heat sources directed to the parts (11, 12) of metal or metallic alloy and following the first heat source (15) in a distance and with substantially the same speed and in the same direction as the first heat source (15). The additional heat source (13) or heat sources are directed to the solidification region (mushy zone) (144) of the melt pool (14) generated by the first heat source (15).

Abstract: A process for selecting for analysis data units from multiple threads of traffic through a single data switch is provided. The process includes capturing all data units of one thread of traffic when said thread is selected by a system administrator, encapsulating data units matching first criteria with identification and forwarding information, and triggering on said captured data units according to second criteria selectable during said process. The process further includes filtering said captured data units according to third criteria selectable during said process and forwarding said filtered data units to a data unit analyzer.
