Less silicates make less post weld cleaning
All-positional seamless metal-cored wire designed for the welding of multi-pass welds without the need of interrun cleaning.
For manual and mechanized welding of unalloyed and fine-grain constructional steels with service temperatures from -30 °C
to +450 °C. Very suited for flat and horizontal fillet welds.
BÖHLER HL 46 T-MC features a stable, spray arc droplet transfer over a wide parameter box and shows very low spatter losses
and an excellent bead appearance.
The seamless, copper-coated wire design adds sufficient stiffness and glide to overcome friction in liners, welding
guns and contact tips. The copper-coating enhances current transfer between contact tip and wire resulting in a stable arc.
Controlled wire cast and helix largely avoids “dog tailing”, promoting straight, well positioned welds. The seamless design offers
the best possible protection against moisture reabsorption during storage and use of the wires and thereby against hydrogen
induced cracking. Diffusible hydrogen level is typically 1 - 3 ml / 100 g weld metal.
Typical applications:
n
General construction such as bridges and stadiums
n
Earth moving and road construction machinery (yellow goods)
n
Medium and thin-plate welding e.g. in shipbuilding
