Arc brazing
Arc brazing is the name given to brazing methods based on arc welding methods. The
most interesting field of applications here seems to be automotive body components
manufactured of zinc coated steel sheet. The reason for this is that conventional fusion
welding often is subjected to different problems due to the burn-off of the zinc coating
and process instabilities such as pores and spatter. Brazing speed can often reach the
double value compared to welding.
In arc brazing heat input is reduced and there is less vaporisation of zinc. The advan-
tages of changing brazing filler metal with the low melting temperature is:
1.Minimal amount of spatter
2.Less post-treatment of the brazed seam
3,Low heat input
4. Low burn-off of the zinc coating
