Laser Brazing Aluminum To Steel

It has advantages in welding dissimilar metals that have great differences in melting point li and wu 2010.

Laser brazing aluminum to steel.

You can also braze the steel with aluminum. Different filler wires have been employed in fusion brazing of aluminum to steel in order to enhance the tensile strength. Welding brazing is considered to be an effective method to solve the problems existing in steel aluminum dissimilar metals welding such as large differences in physical properties and brittle intermetallic compounds. Second weld the aluminum to the dipped steel.

The authors concluded that the geometry of the weld concavity and wetting. Once the metals are cooled the materials will have been successfully bonded to one another. Using laser beam as main heat source and trailing arc as an assisted role aluminum alloy was joined to galvanized steel in a butt configuration. Under suitable welding parameters a sound welding.

Laser powers of tandem beam and offset distance of preheating beam from the root to the steel base metal were varied. 12 a which contained three aspects. The primary joining mechanism of large spot laser assisted gma brazing fusion welding of al to galvanized steel was identified which could be summarized into two factors. Our results our results revealed that relatively sound brazing beads with without a few defects were obtained at high brazing speeds of up to 4 0 m min.

In this work we present the technology of a laser welding brazing lwb process to join zinc coated steel and aluminium sheets in an overlap geometry. Laser fusion brazing process combining the advantages of fusion welding and brazing is an effective approach to weld aluminum to steel. The process is divided into welding of the. Have discussed the importance of global geometry of fillet welds in laser brazing applied to steel to aluminium joints mathieu et al 2007.

The first factor was the effective function of laser beam fig. First dip the steel into melted aluminum to coat it. Laser brazing lb provides a promising way to join the galvanized steel in automotive industry for its significant advantages including high speed small heat affected zone and high welding seam quality.
