J.F. Lancaster, in Metallurgy of Welding (Sixth Edition), 19994.3.5 Braze welding Braze welding or bronze welding is a fusion-welding process that utilizes 60/40 brass as a filler metal with brazing-type fluxes to aid wetting. It was originally developed for the repair of cast iron parts and is still useful for this purpose because the thermal cycle is less severe than in normal fusion welding

Welding | Industrial Services

Welding Welding is a metal joining process in which two pieces of metal, touching each other, are melted at the edges by a welding gun to fuse them together. When the metals cool down, a strong bond is created. Welding can be done by using either pressure or

Welding and soldering: A simple introduction

2/6/2020· I f you''re building almost anything that uses metal, from a nuclear submarine to a laptop computer, one thing you''ll need to be able to do is join metals together. Welding is a way of tightly bonding two metals by melting them where they meet, while soldering involves making a joint between components in an electric or electronic circuit.
