This method requires good preparation stages of weld
groove and pipe alignment.
Using GMAW also enables users to add filler metal to adjust the weld
's metallurgical properties and create beads and fillets, while the lower cooling rate reduces weld
While each technology has its benefits, in practical terms, many component designs incorporate both EB and laser welds
. In these cases, performing both types of welding at the same facility definitely streamlines the manufacturing process.
Microstructure of laser-TIG hybrid welds
of dissimilar Mg alloy and Al alloy with Ce as interlayer, Scripta Materialia, Vol.55 (April 2006), pp.383-386, ISSN 1359-6462
IPG has developed a new inline weld
monitoring system, based on technology originally developed by Laser Depth Dynamics--a Canadian start-up launched in 2012, acquired by IPG in late 2017--that takes full advantage of these recent advances.
Correlation of microstructure and hardness of two-pass submerged arc welds
of line pipe steel X65, International Journal of Microstructure and Materials Properties 4: 347-355.
There is a misconception that in-process weld
rework is generally harmful to the structural integrity of a cast part.
This step is required to ensure that all welds
have comparable quality level in accordance with ISO 10042 (Welding --Arc-welded joints in aluminium and its alloys--Quality levels for imperfections).
For sheet metal, use brief tack welds
. If you try to run a weld
bead on sheet metal it will warp or burn right through.

," Journal of Strain Analysis for Engineering Design, vol.
The strain at break of various welds
is summarized in Table 1, the strain at break of non-welded POM is also introduced as reference value.
