A
seam weld was made on two sheets of galvanized
steel in 100% argon atmosphere. The two sheets
varied in thickness, one having a thickness
of 0.7 mm, the other 1.4 mm. There was a pre-set
500 m m gap between the two sheets being welded.
The welds were exceptionally smooth and exhibited
low distortion and were not embrittled due to
good gas coverage. For a lap joint the long
weld pool allows the zinc to escape before the
pool solidifies, thus yielding a full penetration
steel weld. |
