What's the difference between braze and weld?

Braze


Definition:

  • (v. i.) To solder with hard solder, esp. with an alloy of copper and zinc; as, to braze the seams of a copper pipe.
  • (v. i.) To harden.
  • (v. t.) To cover or ornament with brass.

Weld


Definition:

  • (v. t.) To wield.
  • (n.) An herb (Reseda luteola) related to mignonette, growing in Europe, and to some extent in America; dyer's broom; dyer's rocket; dyer's weed; wild woad. It is used by dyers to give a yellow color.
  • (n.) Coloring matter or dye extracted from this plant.
  • (v. t.) To press or beat into intimate and permanent union, as two pieces of iron when heated almost to fusion.
  • (v. t.) Fig.: To unite closely or intimately.
  • (n.) The state of being welded; the joint made by welding.

Example Sentences:

  • (1) Tests were undertaken to study resistance to tears in laser welded dental metal alloys.
  • (2) The possibility of contaminating the breathing air zone with hazardous substances in manual and semi-automated welding increases with the intensity of their formation in the arc zone.
  • (3) Laser repair has not been widely accepted both because the effect of laser irradiation on intact nerves is not well documented, and the anastomotic strength of the weld has been inferior to suture repair.
