Design & Applications of Consumables for Welding without Hydrogen Cracking

Abstract

Electric arc welding has been with us for a very long time Because of its verstality, its appears that this process will dominate the field of joining metals and alloys for many more years

The first steps in electric arc welding were taken by Bernados and Olszewaki in 1885 when they patented a method of welding using an arc struck between a carbon electrode and the workpiece. The direct use of a metal-arc electrode was patented in the U.K. by N. Salvianoff in 1890.
