An arrangement for measuring the sufficiency of flux present in an electroslag welding process. In electroslag welding a space is formed between parts to be welded and a wire electrode is fed into said space through a tubular flux coated guide, both wire and guide including the flux thereon being melted to form the weld between parts when heat produced by resistance to electricity flowing therethrough is sufficient. The quality of the weld produced, is to a large extent, dependent upon the adequacy of the flux present at the site of the molten metal forming the weld. Frequently however, the weld is obscured from direct observation and only by indirect sensing as permitted by an arrangement such as provided by this invention is it possible to determine the quality of the weld being made.
