No. Welding involves the melting of the base metal and may take place with or without a filler metal. Brazing involves the melting and re-solidification of a filler metal to form a joint between two base metal components. There is some diffusion of the filler metal into the base metal during brazing but no melting […]
Can a vacuum furnace be used for both hardening and tempering?
Yes, it can, but there are some issues to consider. A standard vacuum furnace heats its load most effectively at temperatures above 1200°F (650°C), the start of the “red heat” range when radiant heating becomes most efficient. Below 1200°F (650°C), temperature uniformity within the furnace becomes a concern. Tempering operations for many alloys take place […]
