BelitcaReai Linde tells YOU how © HE oxy-acetylene process of welding and cutting is a growing art. Methods are con- stantly ‘being improved. New applications are being devel- oped. Through a large field organ- ization of welders and en- gineers, Linde has hundreds of contacts and keeps in intimate touch with these new develop- ments. _And for the benefit of Linde customers, procedure controls have been prepared. Each procedure control contains detailed instructions on some welding or cutting operation. One tells about welding tanks, another about pipe lines, a third about repairing castings. Still others deal with newer developments such as monel, aluminum and copper welding. Expert welders and pro- gressive production men use these Linde procedure con- trols and have found by experi- ence that they are invaluable.
