METHOD FOR PRODUCING A STARTING BLOCK FOR FURTHER PROCESSING TO FORM A MATERIAL COMPOSITE, METHOD FOR PRODUCING A MATERIAL COMPOSITE, AND STARTING BLOCK

摘要

The present invention relates to a method for producing a starting block for further processing to form a material composite, wherein, in a first step, at least one first and second preliminary component are provided, wherein, in a second step, a weld is formed between the preliminary components, characterized in that the weld is formed in a first region using a first group of welding parameters, wherein the weld is formed in a second region using a second group of welding parameters, wherein the first group of welding parameters and the second group of welding parameters differ in at least one of the following welding parameters: -- filler metal used, -- heat application used, in particular in terms of current, voltage, welding rate and/or relative thermal efficiency of the welding method, -- preheating temperature used, -- available diffusible hydrogen.
