RE: [MW:11239] RE: 11149] Re: Reduction temperature for LTCS

When a proper and approved procedure is available for this kind of material
and there is nothing wrong with the base material I would say dismiss the
welder and find a better one.
In such case you need to cut out the weld and remove a part of base material
influenced by the welding heat and create new bevel. After that try again
with a suitable welder to weld without failures.
